2 Outline of gear head Features Various s of gear heads are available. The X is available in a metal bearing model and or a ball bearing. The P (9 mm only) is high torque : its maximum permissible shaft torque is N m ( reduction s from / to /8 are available for the X ; reduction s from / to / are available for the Y and Z s. When the decimal gear head (reduction : /) is used, a reduction of up to /8 (/ for the Y and Z s) can be attained. The X and Z of 9 mm are available in right-angle.

3 Outline of gear head Maximum permissible torque There is a limit to the strength of a gear due to its material and construction. The usable load torque determined based on this limit is called permissible torque. As can be seen from the above-mentioned formula, the load becomes larger when the reduction is increased. If the gear head is used with the load exceeding the permissible torque, its life expectancy will be shortened significantly. Refer to the following graph and the permissible torque for each model and use the gear head at an appropriate load. Nominal reduction and actual reduction e that there is a difference between the nominal reduction and actual reduction of each gear head. Refer to the table below. When using the gear head, calculate the speed based on the actual reduction. * Gear heads dedicated to C&B s have the same nominal reduction and actual reduction. Example: nominal reduction /; actual reduction / For practical use, calculate the speed based on the actual reduction.

Gear head efficiency and ambient temperature Calculate the actual gear head efficiency by multiplying the above-shown gear head efficiency at room temperature by the torque reduction shown below. Torque reduction [%] 8 8 % 8 % 7 % 4 [ C] Ambient temperature 7 % 7 % 7 % % 8 % 8 % 8 % 8 % 8 % Overhung load and thrust load The overhung load is defined as a load applied to the output shaft in the right-angle direction. This load is generated when the gear head is coupled to the machine using a chain, belt, etc., but not when the gear head is directly connected to the coupling. As shown in the figure below, the permissible value is determined based on the load applied to the L/ position of the output shaft. The thrust load is defined as a load applied to the output shaft in the axial direction. Because the overhung load and thrust load significantly affect the life of the bearing, take care not to allow the load during open to exceed the permissible overhung load and thrust load shown in the table below. Overhung load and thrust load Service factor Permissible load list Life expectancy of varies depending on load fluctuation. To determine the life expectancy, a factor called service factor, as shown in the table below is used.first choose the appropriate service factor according to the of load and multiply the result by the required power to determine the design power. Service factor Type of load Constant Light-impact Medium-impact Heavy-impact L W (Overhung load) L L d F (Thrust load) Typical load Belt conveyor, One-directional rotation Start/Stop, Cam-drive Instant FWD/REV, Instant stop Frequent medium-impact 4 mm (. inch ) mm (. inch ) 7 mm (.7 inch ) 8 mm (. inch ) 9 mm (.4 inch ) 9 mm (.4 inch ) High torque 9 mm (.4 inch ) Right-angle hours/day The required allowable shaft torque TA of the gear head can be determined based on the service factor and actual load torque T: TA = T x Sf TA : Allowable torque of gear head (N m) T : Actual load torque (N m) Sf : Service factor Use the so that the allowable torque TA calculated from the formula above falls within the allowable torque range. * Though it seems that the can be operated even in overload when the service factor is.8, note that the service factor is defined for the allowable torque of the gear head.

When the service factor is., for example, the life expectancy is calculated as follows: Life expectancy = (h) /. = (h) Prepan () Prepare a gear head that matches a described in this manual. Use of incompatible gear head will cause malfunction. () Check O-ring being correctly placed in a right place. If it is not, this may result in grease in the gear head coming out.

Do not damage the tooth of the pinion and gear head. Incorrect assembly results in abnormal noise genen or shortened unit life. Will cause malfunction. Screws You may experience a sliping gear contact due to broken pinion tooth, locked gear or leaked grease as the gear head life comes closer. Place a safety device to keep safe open at any time even if such problems take place. Assembling () Place the unit so that the shaft faces up. Direction of the lead and output shaft of gear head must match an application. () Do not contact a tooth tip of pinion shaft to a tooth tip of gear head. Set each toothes of and gear head correctly and gently press and turn the gear head in counter and counterclockwise. () To attach the gear head to an application, use the "attaching screws" supplied with the gear head and tighten the screws with appropriate torque and with care not to pinch the O ring, so that the there is no gap between flange and gear flange.

Place an oil pan to prevent oil from coming out in an application like food/textile etc. Do not place an encoder, sensor, contact, etc near a gear head where the grease may leaking out. If not, please have a protection from grease. Have a routain check of the gear head to avoid unexpected accident. <Precautions> Keep the gear head to the. Otherwise, the O ring may become distorted or damaged, causing grease leakage. When reassembling, first replace the O ring with a new one. When installing a associated with the gear head to the application device, temporarily secure the and gear head with a tape until assembly completes. Considens for storage of gear head When storing the gear head as a single unit, place it with the output shaft facing down. (To prevent grease leakage) Gear head Tape Motor B-48 B-49

11 Outline of Gear head -inch (U.S.A.) Features These gear heads are designed according to inch system. All bearings are ball bearing. reduction s from / to /8 are available for the X ; reduction s from / to / are available for the Z s. When the decimal gear head (reduction : /) is used, a reduction of up to /8 (/ for the Y and Z s) can be attained.
