Please select the most suitable products by carefully considering the characteristics of items and contents of the product tables. It is also important to read all applicable “CAUTION” notes shown below before the final selection.

Basically, KHK stock bevel gears should be selected as shown in the catalog in pairs (Ex: MBSG2-4020R should mate with MBSG2-2040L). But, for straight tooth bevel gears, there is some interchangeability with different series. For plastic bevel gears, we recommend metal mating gears for good heat conductivity.

The gear strength values shown in the product pages were computed by assuming a certain application environment. Therefore, they should be used as reference only. We recommend that each user computes their own values by applying the actual usage conditions. The table below contains the assumptions established for these products in order to compute gear strengths.

NOTE 1: The gear strength formula is based on JGMA (Japanese Gear Manufacturers Association) specifications. “MC Nylon Technical Data” by Nippon Polypenco Limited and “Duracon Gear Data” by Polyplastic Co. Also, the units (min-1) of number of rotations and unit (kgf/mm2) of stress are adjusted to the units needed in the formula.

NOTE 2: Since the load is bidirectional, the allowable bending stress at root σFlim, used in JGMA 403-01 formula is set to 2/3 of the value.NOTE 3: The value for DB m0.5 was assumed by KHK.

CAUTION: The allowable torque of MHP High Ratio Hypoid Gears is the actual measured value when the pinion is rotating at 600 min-1.

① MBSA(B) finished bore spiral bevel gears are carburized throughout so that they do not permit any secondary operations. However, the back surface of B7 style gears (ring type) is masked during the process so that it is possible to drill and pin on this surface.

②The keyway sizes of MBSA(B) finished bore spiral bevel gears are made according to JIS B 1301, medium quality (Js9), but the final heat treating may cause some deformation.

③ The bore of SBS spiral bevel gears may somewhat be deformed due to heat treatment and do not reach H7 tolerance.

④ Due to the characteristics of the material, PB plastic bevel gears’ product quality may be affected by heat or moisture absorption.

See the similarly titled section for miter gears.

⑤MBSA(B) finished bore spiral bevel gears are carburized throughout, so that no secondary operations can be performed (except B7 style items). For items with induction hardened teeth, such as SBSG and SBS series, the hardness is high near the tooth root. When machining the front end, the machined area should be 4 to 6mm smaller than the dimension, J.

⑥ For tapping and keyway operations, see the examples given in “1. Caution on Performing Secondary Operations” in KHK Stock Spur Gear section. When cutting keyways, to avoid stress concentration, always leave radii on corners.

⑦ PB plastic bevel gears are susceptible to changes due to temperature and humidity. Dimensions may change between during and after remachining operations.

⑧ When heat treating S45C products, it is possible to get thermal stress cracks. It is best to subject them to penetrant inspection afterwards. While the teeth strength may increase four fold, the precision of the gear will drop approximately one grade.

⑨ For the handling conveniences, SB and SBY series listed below has the tapped holes (180° apart, 2 places) on the holding surface.

In order to use KHK stock gears safely, carefully read the Application Hints before proceeding. For “Notes on Starting Operations” and “Other Points to Consider in Applications”, please see the Application Hints of Miter Gear Selection.

① If you are reboring, it is important to pay special attention to locating the center in order to avoid runout.

② The reference datum for gear cutting is the bore. Therefore, it is best to use the bore for locating the center. If it is too difficult to do for small bores, the alternative is to use one spot on the bore and the runout of the side surface.

③If reworking using scroll chucks, we recommend the use of new or rebored jaws for improved precision. Please exercise caution not to crush the teeth by applying too much pressure. Any scarring will cause noise during operation.

Lathe Operations

④The production of bevel gears module 2.5 and over with a pinning hole on the back of the hub in non-ground teeth has been phased out as of August 2003. However, we may have some stock of this configuration.

① Since bevel gears are cone shaped, they produce axial thrust forces. Especially for spiral bevel gears, the directions of thrust change with the hand of spiral and the direction of rotation. This is illustrated below. The bearings must be selected properly to be able to handle these thrust forces.

② KHK stock bevel gears are designed such that, when assembled according to the specified mounting distance with a tolerance of H7~H8, the backlash shown in the table is obtained. Mounting distance error, offset error and shaft angle error must be minimized to avoid excessive noise and wear. For various conditions of teeth contact, please see page 198 "Correct Tooth Contact" and "Incorrect Tooth Contact".

③ If a bevel gear is mounted on a shaft far from the bearings, the shaft may bend. We recommend mounting bevel gears as close to the bearings as possible. This is especially important since most bevel gears are supported on one end. The bending of shafts will cause abnormal noise and wear, and may even cause fatigue failure of the shafts. Both shafts and bearings must be designed with sufficient strength.

④ Due to the thrust load of bevel gears, the gears, shafts and bearings have the tendency to loosen up during operation. Bevel gears should be fastened to the shaft with keys and set screws, taper pins, step shafts, etc.

⑤ When installing MBSA(B) spiral bevel gears in B7 style (ring type), always secure the gears onto the mounting base with taper pins to absorb the rotational loads. It is dangerous to secure with bolts only.

■ Features of MHP High Ratio Hypoid Gears

■ How to determine the radial and thrust loads

1. Total-cost reductionThe MHP provides a compact gearing body replac ing severa l s tages of reduction gears. This reduces the cost sharply.

2. High efficiencyCompared to worm gear drives, the MHP has less sliding contact. The resulting higher efficiency allows the use of smaller motors (See the graph on the right).

3. High rigidityThe carburized hypoid gears lead to smaller size than comparable worms gears.

4. Compact gear assemblyThe size of the gear housing is nearly the same as outer diameter of the large gear. (See the diagrams below)

NOTE 1: Factors to be used for calculating radial and thrust loads, CW and CCW stand for clockwise and counterclockwise rotation, respectively. See B8 Shape above. A plus sign means that two gears in a set are apart from each other when load is applied. A minus sign means that they approach each other when load is applied. For the method of calculation, see “How to determine the radial and thrust loads” on page 232.

NOTE 2: The allowable torques are obtained from the results of experimentation with the pinion at 600 min-1 lubricated with Kingstar SG-O (NIHON GREASE).

CAUTION: With the exception of B7 type gears, dimensions of the outside diameter, the overall length and crown to back length are all theoretical values, and some differences will occur due to the corner chamfering of the gear tips.CAUTION: The products which are hardened by carburizing allow no secondary machining, however, the back surface of B7 type gears is masked during the process so

that it is possible to drill and pin on this surface.

CAUTION: Dimensions of the outside diameter, the overall length and crown to back length are all theoretical values, and some differences will occur due to the corner chamfering of the gear tips.NOTE1: Due to heat treating, some deformation of the bore may occur. It may be necessary to ream the bore to bring it to the stated dimensions.

■ Regarding the Transmission Capability Table1. The values given in the table are for a service factor of 1.Using the table on the right, please modify the value according to the actual conditions.2. For speed increaser applications (where the gear is the driver and the pinion is

driven), the torque on the pinion is the value in the table multiplied by the speed ratio.(Ex.) For speed ratio of 1/1.5, the torque on the pinion is 1/1.5 times the value given in the table.

■ Adjusting Tooth Contact

(1)When there is an angular error of the shafts＜ Centering tooth contact ＞

(1)When assembled correctly, the contact will occur in the middle of the tooth flank.

(2)The contact in the face width direction should be in the center of the face width, but somewhat closer to toe is ideal.

When the gears are assembled in to the gearbox and the backlash is adjusted, adjust the gearbox to obtain the tooth contact as shown below. Inaccurate assembly will lead to irregular noise and uneven wear,

(2)When the pinion shaft is offset (3) When the mounting distance of the pinion is incorrect
