FAQ
Q1: Is the L-shaped synchronous pulley compatible with other gear types (such as T5, HTD)?
A: The L-type is an independent toothed standard and needs to be used with a corresponding L-type synchronous belt. If compatibility with other tooth types is required, please contact customer service to customize special specifications.
Q2: How to choose the appropriate number and material of belt teeth?
A: The number of teeth depends on the transmission ratio and motor speed. It is recommended to refer to the formula: number of teeth=motor speed x number of driving teeth ÷ driven wheel speed.
The material should be selected according to the load: aluminum alloy is suitable for light load and high-speed scenarios, while quenched steel is suitable for heavy load and impact conditions.
Q3: How to ensure the concentricity between the pulley and the shaft during installation?
A: It is recommended to use the expansion sleeve fixation method or calibrate the radial runout of the keyway after installation with a dial gauge (≤ 0.05mm).
Q4: Will the pulley fail in high temperature environments?
A: Standard materials (aluminum alloy/quenched steel) can work stably below 150 ° C; If a higher temperature environment (such as 200 ° C) is required, special stainless steel material can be selected (customized).
Q5: What could be the possible cause of abnormal noise during the use of the pulley?
A: Common reasons include:
Insufficient tension or excessive wear of synchronous belt
Loose fit between pulley and shaft
Axis parallelism deviation>0.1mm
Suggest checking and adjusting the tension, or replacing damaged components.
Q6: Does the product have rust prevention treatment?
A: Aluminum alloy pulleys come standard with a hard oxide coating, and quenched steel can be treated with nickel plating or blackening. No additional rust prevention maintenance is required in regular environments.
