Helical Gearboxes manufacturers

Guangdong Xingguang Transmission in Foshan supplies R coaxial helical, K bevel-helical, RV worm and other standard geared drives, with motor and inverter options. Compare shaft arrangement, legacy frame torque references and a matched operating point before specifying the complete drive package.

Pingyao XINKAI in Shanxi supplies QJ/QY crane reducers, YN permanent-magnet semi-direct drives, modular replacement units and other heavy-duty industrial transmissions. Match the machine load cycle, shaft interfaces, housing construction and agreed acceptance testing before selecting a frame.

Zhejiang Xinghai Reducer publishes gearmotor and reducer ranges spanning parallel-shaft helical, helical-bevel, worm-helical, industrial gearboxes and cycloidal pinwheel units. The official FF series page provides motor-power, output-speed and torque envelopes together with a frame table; the BW/XW cycloidal page explains continuous service, recommended input speed and mounting inclination. These represent separate drive principles and should be compared by output speed, load and mounting arrangement, not by a common headline ratio. The company site also lists materials and usage conditions for the cycloidal range. Request a frame-specific catalogue and dimensional drawing before placing an order.

Tunsing Transmission, the brand shown by Zhejiang Gear Reducer Motor, publishes reducer families with official illustrated selection tables. Its R series is an inline helical drive, while the K series changes direction through helical-bevel gearing. Both pages show installation arrangements, frame sizes, ratio ranges, motor power and permissible torque by model. The examples below use the R37 and K37 columns so that a buyer sees a coherent frame-level selection rather than disconnected series maxima. The company also lists motors and other reducer architectures. The official tables are source material for preliminary screening; final shaft, mounting and duty selection requires a current drawing and quotation.

Anhui Feluoka Heavy Industry Transmission publishes modular geared-motor families for industrial drive installations. Its K series combines helical and bevel gearing to turn the output axis, while its R series is an inline helical arrangement. Separate official pages state each family’s ratio, rated-output-torque and motor-power envelopes, and enumerate available output and motor interfaces. Buyers can compare the arrangements as a starting point but should request a model-level selection sheet at the intended input speed, duty cycle and mounting orientation. The site also shows frame-by-frame torque charts rather than a single universal rating.

Hangzhou Jiacheng Machinery manufactures worm and gear reducers and publishes products under the Chen Chao name. Its official range includes JCR, JCF, JCK and JCS geared drives, WP and NMRV worm units, and SWL screw jacks. The company website identifies operations dating to 1992 and a Hangzhou Dajiangdong location. The JCR and NMRV pages offer numerical family envelopes for ratios, power and output torque, with separate single- and double-stage limits for NMRV. These are catalog boundaries rather than interchangeable operating points. Buyers should obtain the full type code, installation drawing and duty calculation for the intended application.

Zhejiang Tongli Transmission Technology supplies industrial reduction gear units and geared drives. Its TR hardened-tooth helical family and TK spiral-bevel family provide two distinct drive layouts: inline transmission and right-angle transmission. Official product pages publish frame envelopes, reduction ratios, output-speed ranges and input-power ranges. These values cover multiple sizes and motor combinations, so their endpoints must not be combined into an assumed configuration. The catalog identifies metallurgy, mining, conveying, chemicals and mixing as application areas. Buyers can use the documented series to shortlist a drive architecture, then obtain a frame-specific drawing, mechanical rating and thermal check from TONGLI.

WUMA supplies worm reducers, helical geared drives, hypoid units and planetary reducers. Its official catalog includes the WMRV right-angle worm family and WR inline helical family, with different housing materials and installation arrangements. The website identifies gearbox manufacturing activity dating to 1995 and lists applications including packaging, ceramics, environmental equipment and conveying. This profile links the CRM company Zhejiang Wuma Reducer to its WUMA brand website; the current website footer also names Zhejiang Wuma Transmission. Confirm the contracting legal entity and selected production location with the supplier. Product descriptions below retain the official family specifications without implying that every size shares the same load capacity.
