Product Describtion
Henan Dongtai Gear Co., Ltd is a famous and experienced manufacturer in China. Our business focus on the high precision gears, gearbox, gear reducer, gear motor, and other mechanical transmission spare parts. Our products have been exported to Europe, Southeast Asia, the Middle East, Africa, South America and many other countries and regions. They are widely used in crane hoist, paper-making, chemical industry, light industry, machine manufacturing, food line, architecture material, wiring, mines, etc. Our products have the excellent quality and high stability, the advanced performance and competitive prices.
Simply select the ideal gear unit for your requirements and benefit from the advantages offered to you by our standard range. The high quality, the fast availability worldwide, and the attractive price level are the main strengths of this range of gear units. Horizontal or vertical mounting positions, different versions of helical, bevel and bevel-helical gear units, and the compact design of our gear units give you maximum flexibility in the design of your plant.
The H series helical gear reducer has sound-absorbable structure, larger surface, big fan reduce temperature and noise, advanced grinding process of cylindrical gear and bevel gear improve stability and transmit power more efficiently.
1.H series gear units adopt currency layout and may transform into special reducer according to customer's requirement.
2. The housing of one size can realize parallel shaftmodes and horizontal mounting modes.Variety of components is reducible, the number of reducer's mode is augmentable.
3. Sound-absorbable structure, lager surface, big fan reduce temperature and noise, advanced grinding process of cylindrical gear and bevel gear improve stability and transmit power more efficeintly.
4.Input mode : motor connected flange ,shaft input.
5. Output mode: solid shaft with flat key, hollow shaft with flat key, hollow shaft with shrink disk, hollow or solid shaft with involute splines , solid shaft with flange.
6. Mounting mode: Foot-mounted, flange-mounted, swing base-mounted, torque-arm-mounted.
