company demonstrate:

Merchandise specification

      1.All the gearboxes are designed in accordance to JB/T9050.1-1999 of a variety of complex regular.
       2.The gears of substance are 20CrMnMo,following carbonize,quenching and equipment grinding,attain 6 precision,the hardness reaches HRC54-sixty two,and the minimal noise.
      3.Domestic leading-top quality ZHJ and DYZV bearings to be adopted,also we can adopt imported brand like SKF,,NSK,which depend on the client.
      4.The cast of gearbox adopt HT250 content exclusively and thick layout,which promise the situation stationarity.This design and style is good for minimizing the sound,warmth dissipation,lubrication of spare areas and an straightforward routine maintenance.
      5.The oil seal undertake the Twaiwan’s manufacturer TTO,the gearbox’s large pace and reduced velocity shafts are all use the double oil seals,which can stop the probability of oil leaking.
      6.The cnection of screw barrel:according the standard of GB/T 1095-1979 adopt the 180° double keyway.also can use the sq. spline GB/T 1144-1987.Any issue of screw barrel’s relationship can be custom-made.

Functioning Situations: 

1. Input shaft rotation pace is not a lot more than 1500r/min. 
2. Its ambient temperature selection is in 0 to 35 centigrade. If it is decrease than 0 centigrade, pre-heating of the CZPT will be essential before commence-up, while CZPT is recommended in circumstance of a temperature larger than 35 centigrade.



The expression “gearbox” is employed to refer to any system that connects a motor to a machine and is composed of a collection of gears, also identified as a gear established. It gets the principal input speed from the motor and changes it to a distinct output velocity using its gears. Various kinds and combinations of gears serve particular functions. The sorts of gears discovered in gearboxes consist of spur gears, bevel gears, helical gears, helical gears and worm gears. The efficiency effectiveness of a gearbox is represented by the gearbox ratio, which is the ratio of the velocity of the input supply to the velocity of the output resource
Gear reducers are also named reducers. Mechanical accessories, by possibly of these two names, are designed to reduce the power transferred between the motor and the device among the rotational speeds (revolutions for every minute). The reducer effectively minimizes the rotational speed created by the motor, thus controlling the velocity at which the equipment operates and rising the torque made by the motor. Multiplying the torque produced by the motor raises the machine’s offered electrical power – a procedure acknowledged as “mechanical dominance”. In a greater context, equipment reducers are fundamentally tools utilized to increase the performance of tools operation.
