TECHMECH

TF Precision Planetary Gear Reducer

The TF series is a precision planetary reducer intended for smooth motion under demanding axial or radial loads. TECHMECH’s product page gives output sizes of 60 to 180 mm and lists single-stage ratios of 3, 4, 5, 6, 7, 8 and 10, with further ratios from 15 to 200 for multistage configurations. Its stated minimum one-stage backlash is at most one arcminute; no complete two-stage backlash number is printed in the source text, so that value needs a model drawing. The maker names AC servo, DC servo, stepper and hydraulic motors as possible drive partners. Verify the motor adapter, bearing load and frame rating for the actual duty point.

TECHMECH

TST Precision Planetary Gear Reducer

The TST is TECHMECH’s right-angle precision planetary series. The official product page identifies output sizes from 75 to 240 mm and lists direct ratios of 1, 2, 3, 4 and 5. A separate gear-reducer combination can extend the reduction to 500:1; that figure describes the combined arrangement, not every single TST unit. The maker describes precision-ground gearing, multiple machined mounting surfaces and installation in any orientation. Choose the output frame and combined or direct drive layout before checking backlash, service life and lubrication details in the current catalogue. A model drawing is needed for shaft and flange fit.

WEILI Transmission

Planetary Slewing Gear Reducers

Weili’s slewing reducer is intended for the rotary mechanism of construction machinery. The official product page documents a planetary reduction arrangement and lists the available ratio and maximum-output-torque envelopes. A slewing-drive quotation should include the driven ring gear, allowable pinion loads, required rotation speed and the full acceleration and stopping cycle. Maximum catalog torque is not a continuous-duty rating and does not independently establish the capacity of the whole slew bearing or machine. Match the selected hydraulic motor, brake and installation interface to the manufacturer’s drawing and request an application-specific mechanical calculation.

WEILI Transmission

Planetary Winch Gear Reducers

Weili’s winch reducer drives a cable drum through a multistage planetary gear train. The manufacturer describes a compact construction, an integrated parking brake and compatibility with several variable- and fixed-displacement hydraulic motor series. Its ratio envelope is 26–420 and the published maximum-output-torque envelope is 7.5–325 kNm. Those maximum values must not be presented as continuous rated torque. A winch selection also needs the drum diameter, line pull, reeving arrangement, speed cycle and braking duty. Confirm the complete motor/reducer/brake assembly and the manufacturer’s load calculation before using it in lifting equipment.

NUODUN

RV Worm Gear Reducers

Nuodun’s RV range uses a compact die-cast aluminum-alloy square housing with multiple motor and shaft interfaces. The official page gives ratios of 7.5–100, with combined two-stage selections reaching 10,000, and an output-torque envelope of 24.6–1,192 Nm. Input power is quoted at 1,400 rpm. IEC and NEMA motor interfaces, solid input shafts and several output formats are listed as options. The source mentions self-locking under certain conditions; this must not be treated as a safety brake or a universal characteristic. Ask for a model-specific selection covering efficiency, temperature rise, mounting position and back-driving behavior.

NUODUN

NDP001 Coaxial Planetary Reducer

The NDP001 rating sheet is published within Nuodun’s ND-LDB5-AM80B5 product documentation. This page extracts the one-stage NDP001L1 configurations at 1,400 rpm input. Actual ratios differ from the nominal selection labels: for example, the nominal 3.55 entry is listed as 3.577 actual ratio, with 125 Nm output torque and 391 rpm output speed. The sheet also gives a 3 kW thermal-power value for the one-stage group. Thermal capacity and mechanical torque are different checks. The configurations here retain the actual ratios; confirm the motor interface, bearing loads and thermal operating conditions with the manufacturer.

Jiacheng / Chen Chao

NMRV Worm Gear Reducers

Jiacheng’s NMRV family is offered as single-stage worm units and combined two-stage assemblies. The manufacturer separates a single-stage ratio range of 7.5–100 from a two-stage range of 100–5,000. Input power is specified as 0.06–15 kW for single-stage units; the two torque envelopes are listed separately below. The source describes an aluminum-alloy construction and multiple installation positions. Check the material and dimensions of the selected frame, as well as oil quantity and thermal duty for the actual orientation. A combined-stage reduction ratio must be evaluated with its own efficiency and permissible output load.

Jiacheng / Chen Chao

JCR Helical Geared Motors

JCR is Jiacheng’s modular helical geared-motor family. The source lists models 37–177, ratios from 3.77 to 267.77 and an input-power envelope from 0.12 to 250 kW. Its published output-torque range spans 3.5–56,845 Nm across the family. The manufacturer describes an integral cast housing and use in frequent starting or reversing duties; an application still needs a service-factor and thermal check. Provide the load cycle, motor requirements and mounting arrangement so the supplier can confirm a complete combination. Do not combine the largest torque and highest ratio into an assumed standard unit.

TIANYI

High-Precision Helical Planetary Gearboxes

Tianyi’s high-precision planetary page describes helical planet and sun gears, an integrated carrier/output shaft and a clamping input connection. The catalog identifies SCM415/420 alloy steel and DIN6 gear accuracy. Its stated efficiency exceeds 97% for one stage and 94% for two stages. The family introduction advertises standard and customized backlash levels, but individual selector entries vary; the ordered frame and precision grade must therefore be checked explicitly. Use the official motor interface and rating sheet to establish torque, input speed and allowable bearing loads rather than applying a headline precision value to every size. The manufacturer image illustrates the TB variant within this family.

TIANYI

TYK / TNK Standard Spur Planetary Gearboxes

The TYK page covers Tianyi’s standard spur planetary family, alongside TNK and TYKH designations. It describes a full-complement needle-bearing arrangement and an integrated planet carrier and output shaft. Published family efficiency exceeds 96% for one stage and 92% for two stages. The page’s introductory backlash claim differs from some selector options, so no single precision value is applied to every frame here. Confirm the exact code and grade before using backlash in a positioning calculation. The public page does not provide a complete rated torque matrix; request that table together with the motor-adapter and output-shaft drawing.

JIAOXING

JHG Helical-Hypoid Gear Reducer

JHG combines a hypoid first stage with additional gearing in a compact right-angle reducer. Jiaoxing lists sizes 50, 63 and 75. Two-stage units cover ratios 7.5–60, while three-stage units cover 80–300. The source identifies a hollow output and notes mounting compatibility with its JMRV range, which should be checked against the actual dimensional drawing before replacement. Ratio ranges describe available combinations, not a torque rating. Provide the motor speed, required output torque, duty cycle and mounting position so the supplier can confirm the correct stages, lubrication and thermal capacity.

JIAOXING

JDLB Precision Duplex Worm Reducer

JDLB uses a duplex worm arrangement that allows mesh clearance to be adjusted by moving the worm axially. Jiaoxing documents six sizes and distinguishes a super-precision option from the standard precision range. The source describes adjustment to below 1 arcmin and a 2–4 arcmin precision option; these are configuration-dependent statements, not an independent measurement of every gearbox. The right-angle layout can suit rotary positioning where the machine needs an adjustable mechanical backlash. Confirm the chosen precision grade, coupling, output bearing loads and continuous torque rating. Adjustment procedures and lubrication should follow the manufacturer’s current manual.
