PC Series Helical Gear Reducers with Front Mounting
The PC series is a front-mounted helical gear reduction unit designed to be used in conjunction with RV reducers. Featuring a modular design, it can be combined with RV-series reducers to achieve two-stage reduction, delivering higher transmission ratios and greater output torque. With smooth operation and easy installation, it represents a classic solution for achieving high‑ratio drive in small and medium‑sized industrial equipment.
- Product Description
-
I. Product Overview
The PC-series helical‑gearbox is a modular front‑mounted reduction unit, specifically designed to be paired with RV‑series worm‑gear reducers. It allows the motor’s output shaft to be connected via a B14 flange, enabling two‑stage speed reduction and amplification to achieve a higher overall gear ratio and greater output torque. This assembly cannot be used independently; it must be installed only in conjunction with the corresponding RV reducer model, making it a classic solution for high‑ratio drive applications in small and medium‑sized industrial equipment.
II. Model Designation and Specifications
- Model designation ：
PC 071
PC: Designation of the front-mounted helical gear reducer071: Frame size (corresponding to dimensions and gear ratio)
- Main Specifications : PC063, PC071, PC080, and PC090 correspond to different mounting dimensions and gear ratios (commonly i = 2.76 / 2.8 / 4.5).
III. Core Structure and Characteristics
- Modular Combined Design
- It can be directly coupled with any RV-series gearbox equipped with a PAM‑standard input flange. The combination of a front-mounted reduction unit and an RV gearbox provides two-stage speed reduction, delivering a higher overall gear ratio and greater torque multiplication while maintaining a compact installation footprint.
- Advantages of Helical Gear Drives
- It employs helical gear transmission, which offers smoother operation, lower noise levels, and higher transmission efficiency compared to spur gears, making it well-suited for continuous, long‑duration operating conditions.
- Standard installation interface
- The output end features a B14 flange, while the input end is compatible with standard motor mounting flanges, ensuring convenient installation without the need for custom modifications. It can be directly paired with conventional motors and RV gear reducers.
- Compatible with multiple RV models
- It is compatible with mainstream RV reducer models such as the RV040, RV050, RV063, RV075, RV090, RV110, and RV130, meeting diverse load and reduction‑ratio requirements.
