PC Series Front Helical Gearbox

PC Series Front Helical Gearbox

PC series front helical gearbox is a product with a modular structure. It can be combined with any reducer with a PAM input flange hole. The front helical gear reducer and motor are output in B14 mode. This device cannot be used alone but can only be used together with the reducer.PC series front helical gearbox is a group of independent gearboxes, but it is not used as a separate reducer, only used as a bridge between the motor and the worm gear reducer. It is used to improve the use efficiency of the reducer so that the reducer with the same model and speed ratio can be flexibly applied to different working occasions.

PC Series Front Helical Gearbox Connecting to Electric Motor

When the PC series front helical gearbox is installed on the motor shaft, the following points should be noted.

1. Clean the motor drive shaft thoroughly;
2. Remove the flat key on the motor drive shaft
3. As shown in the figure below, put the shaft sleeve ① on the drive shaft. For easier installation, heat the shaft sleeve to about 70-80 ℃ c
4. Install the new flat key ③ onto the drive shaft keyway
5. With reference to the method of c, put the pinion ④ on the drive shaft
6. Put on the gasket ⑤ and tighten the bolt ⑥
7. Remove the rubber cap from the oil seal. Be careful in this step because the PC has been filled with lubricating oil.
8. Mount the oil seal ② and other motor components, and be careful not to damage the oil seal

FAQ

Q: How to maintain the gearbox?A: After a new gearbox has been used for about 400 hours or 3 months, the lubrication needs to be changed. After that, the oil changing cycle is about every 4000 hours; please do not mix-use different brands of lubrication. It should keep enough amount of lubrication in the gearbox housing and check it regularly. When it is found that the lubrication has deteriorated or the amount is decreased, the lubrication should be changed or filled up in time.Q: What should we do when the gearbox is the breakdown?A: When the gearbox is a breakdown, do not disassemble the parts first. Please contact the relative sales representative at our Foreign Trade Department and provide the information shown on the nameplate, like gearbox specification and serial number, time used, fault type, as well as the qualtity of problemed ones. Finally, take the appropriate action.Q: How to store the gearbox?A: a) Protected against rain, snow, humidity, dust, and impact.b) Place wood blocks or other material between the gearbox and the ground.c) The opened but not used gear units should be added with the anti-rust oil on their surface and then returned back to the container in time.d) If the gearbox has been stored for 2 years or an even longer time, please check the cleanliness and mechanical damage and whether the anti-rust layer is still there during the regular check-up.Q: What should we do when unusual and even noise occurs during the gearbox running?A: It is properly caused by the uneven mesh between gears, or the bearing is damaged. The possible solution is to check the lubrication and change the bearings. Moreover, you can also ask our sales representative for further advice.Q: What shall we do about the gearbox oil leakage?A: Tighten the bolts on the surface of the gearbox and observe the unit. If the oil is still leaking, please contact our sales representative at Foreign Trade Department.Q: Do you sell motors?A: We have stable motor suppliers who have been operating with us for a long-time. They can provide motors of high quality.
