TANHON · Zhejiang Tianhong Transmission MachineryTANHON
Specify the industrial drive from its shaft connection outward.
TANHON's MTH heavy-duty helical range spans several stages, mounting forms and output connections. For a conveyor, mixer or other sustained-duty machine, begin with how torque and external loads enter the driven shaft. Then select the frame, lubrication, cooling and foundation as a complete installation.
Heavy-duty parallel-shaft family
MTH is a configuration range.
The official H (MTH) page lists one- through four-stage builds, with frame availability depending on stage count. It gives an output-speed envelope of 1.7–1,200 rpm, input-power range of 1.5–4,946 kW and output torque up to 900,000 Nm.
These are portfolio endpoints across configurations. They are not the simultaneous rating of the pictured MTH2HH6 or a selected ratio. Obtain the exact frame's mechanical and thermal rating at the supplied motor speed, actual duty and mounting position.
Named applications include iron/steel, chemicals, conveying, cement, mining and lifting. Specify the machine and load cycle so the supplier can choose service factors, bearing loads and auxiliaries for that installation.
Existing MTH product information →Define the output connection before asking for a replacement.
The official model list distinguishes horizontal foot mounting, horizontal designs without feet and vertical mounting. Within them, shaft-connection options require different mating parts and assembly access.
Coupling and bearing loads
Send the shaft diameter, key, fit, coupling and centre-line drawing. Identify radial/axial loads and the coupling's permitted misalignment. Agree base alignment and access to remove the coupling without dismantling adjacent machinery.
Driven-shaft fit and removal
Provide the driven shaft's diameter, keyway, tolerances and engagement length. Define torque reaction and axial retention. Include space and method for fitting, inspection and later extraction from the driven shaft.
Clamping assembly as a supplied scope
Confirm the shrink disc, shaft fit, clean/lubricated surfaces according to the manufacturer's assembly instructions, tightening procedure and torque-reaction arrangement. Specify the exact clamping kit and removal provisions.
A mating spline drawing
The official list references DIN 5480 splined hollow shafts. Request the complete spline designation, fit and engagement drawing; “splined output” alone is insufficient to manufacture the mating shaft.
Pilot, bolts and supported load
Show the mating flange pilot, bolt circle, fastening and driven assembly. Give bending moment and axial/radial force at the real load positions. Confirm which bearings support the load and how the flange is inspected.
An industrial gearbox quote should include its auxiliaries.
Use the following scope discussion for the selected MTH installation. These are procurement questions, not assertions that every option is standard equipment.
Mechanical duty
Define the load spectrum.
Provide continuous torque, startup/repeated peaks, jams, reverse running and stops with duration and frequency. Include operating hours, input/output speeds and external shaft forces. For lifting-related machinery, specify brake/backstop/control requirements with the machine designer rather than relying on gearbox reduction alone.
Thermal and lubrication
State the installation conditions.
Provide ambient temperature, ventilation, mounting position, oil-system access and duty. Request lubricant grade/quantity, oil levels and lubrication points. Agree whether a fan, forced oil circulation, cooler, heater or monitoring is needed, with power and interlock responsibilities.
Foundation and maintenance
Plan installation and removal.
Send foundation, base plate, motor/coupling layout and service envelope. Agree alignment procedure, fastening, guarding, lifting points, oil-change access and spare-parts identification. For a retrofit, compare the current measured drawing and nameplate before accepting a nominally similar frame.
Official facility photographs
Connect the production process to the delivery records.
The company describes gear grinding, CNC machining and gear-analysis equipment. For the ordered gearbox, agree gear and housing materials, heat-treatment requirements, dimensional inspection, assembly traceability and the actual no-load/load test scope. A facility photograph does not replace a serial-specific report.
A documented historical engineering project
Ruian's Science and Technology Bureau published a December 2022 acceptance notice for project GY2022069, undertaken by Zhejiang Tianhong: a reducer for a high-temperature galvanising manipulator. The notice describes combined motion control, sealing and lubrication work and records project acceptance. This is useful engineering-history context; it does not certify the MTH family's current ratings or make every model suitable for that temperature.
The official footer also names Hangzhou Honix Import & Export alongside the manufacturing company. Confirm the contracting/exporting entity, manufacturing site, inspection responsibility and warranty contact for an overseas order. Use current company and certificate documents where the contract requires them.
Request a complete industrial-drive selection.
Include the connection and auxiliary scope so competing proposals cover the same installation.
- Machine, quantity and new drive or retrofit requirement.
- Motor, input/output speeds, ratio and complete torque cycle.
- Output-shaft type, mating drawing and external forces.
- Mounting orientation, foundation and torque reaction.
- Ambient conditions, running hours and thermal capacity.
- Lubrication/cooling, monitoring and interlock responsibilities.
- Material, drawing revision and agreed acceptance tests.
- Manufacturing/exporting entity, spares and warranty route.
