One-cycle Motor

One-cycle Motor

Gear motor with one-turn control clutch

A one cycle motor is a product developed mainly for rotational positioning of screws and screw caps in plastic molds that use screw cores.

This is a motor unit that can be positioned simply by supplying power from the molding machine to the motor's main power supply and solenoid (solenoid valve). By using a simple clutch without using a sensor, etc., there is no differential product error. It can be used as a substitute for servo motors for screw products that require positioning. Due to its simple structure, maintenance is easy. It is widely used in molds for medical, cosmetic, and beverage containers.

When the solenoid is energized while the motor is energized, the power of the motor is transmitted to the output shaft side by returning the clutch, and it stops accurately at the position of 360 degrees in one rotation. By adjusting the energization time to the solenoid, it is possible to stop at 2 rotations, 3 rotations, and integral rotations.

Inspection and replacement items	Approximate intervals	Criteria for parts replacement
gear motor parts grease change	4-5 years	Replace every 20,000 hours or every 5 years. When used for operation in a high temperature place or continuous operation, Replace after 15,000 hours as a guide.
clutch parts grease change	6 months	If there is any abnormality even before the interval, replace the grease. Apply a thin layer of grease to the outer circumference of the inner ring, the roller and the inner circumference of the outer ring. The decomposition method is as follows. 1. Remove the top cover and loosen the motor mounting bolts. 2. With the output shaft facing up, use your finger to remove the clutch lever from the clutch cam through the hole in the top cover. 3. If you lift it as it is, the motor part and the clutch parts will separate. 4. Apply a thin layer of the specified grease to the peripheral surface. 5. Assemble in the reverse order.
re-tensioning the chain	6 months	If the chain is loose, re-tension it.
Loosening of tightening bolts	6 months	Tighten the mounting bolts if they are loose.
oil seal replacement	5 years	If any abnormality is found, replace it.
O-ring	1-2 years	When disassembling, be sure to replace it with a new one.
