Product Presentation

This micro timing belt pulley adopts integrated precision tooth profile machining, with a concentricity error of ≤0.01mm. It has good wear resistance and high transmission efficiency, which can effectively reduce belt slip and wear, and extend the service life of the transmission system.

Traditional micro pulleys have insufficient tooth profile accuracy, which are prone to belt detachment and transmission deviation, with high noise and short service life during long-term operation.

Recommendation: When placing an order, please provide parameters such as belt model, tooth pitch and mounting shaft diameter to ensure precise adaptation to the belt and transmission shaft, and guarantee transmission stability.

Advantages

Ultra-small size, suitable for harsh space

The minimum outer diameter is 4mm, and the thickness is only 1.5mm, which reduces the volume of traditional pulley installation by 70%. It is specially designed for space-constrained equipment, and can be installed compactly in precision equipment such as semiconductor lithography machine and minimally invasive surgical instruments, without occupying too much space.

Multiple material options to handle complex working conditions

We offer aluminum alloy, stainless steel, and PEEK plastic. Aluminum alloy weighs less than 5g; stainless steel is resistant to acid and alkali corrosion, making it ideal for medical equipment disinfectant environments; PEEK plastic provides non-magnetic insulation, suitable for special scenarios like MRI machines, meeting the performance requirements of various usage environments.

High-precision machining ensures precise transmission

Utilizing the slow wire EDM process, the gear accuracy meets ISO 5 standards. When paired with a polyurethane synchronous belt, the transmission positioning error is less than 0.01mm, meeting the stringent transmission accuracy requirements of high-end manufacturing equipment such as wafer handling robots, ensuring stable and accurate operation.

Optimize gear design to reduce operating noise

Adopt arc gear, effectively control the transmission noise below 45dB, compared with the traditional trapezoidal gear belt noise reduced by 30%. In the laboratory and precision testing equipment operation, can reduce noise interference, create a quiet working environment.

Frequently Asked Questions

Q: How to install miniature timing belts and pulleys to avoid deformation?

A: Special miniature fixture should be used, and the torque should be controlled at 0.5-1N・m. It is recommended to use the thermal expansion and cold contraction method to install (the aluminum alloy wheel should be heated to 80℃ and then fitted with the shaft) to avoid damage from knocking.

Q: What is the maximum speed that miniature timing belts and pulleys can withstand?

A: Aluminum alloy material can reach 12000rpm (dynamic balance correction is required), plastic material is recommended to be less than 5000rpm, beyond this range may cause tooth deformation due to centrifugal force.

Q: What is the minimum order quantity for miniature timing belts and pulleys?

A: Jiesheng Transmission provides flexible customization services. The order quantity for small batch sample is 10 pieces, which makes it convenient for customers to quickly verify product performance in the R&D stage. When the batch production (more than 1000 pieces) is produced, the unit price can be reduced by 40%, effectively helping customers control costs.
