Description
Technical field
The utility model relates to tension equipment technical fields, more particularly to a kind of belt stretcher.
Background technique
Transmission device is the intermediate equipment for the power of power device being passed to operating mechanism etc..The basic training of transmission system
With being the driving wheel that the power of engine sending is transmitted to automobile, driving force is generated, automobile is enable to travel on certain speed.
V belt translation is a kind of machine driving that movement or power transmitting are carried out using the flexible-belt being stretched on belt wheel.According to
The difference of transmission principle has the Friction Type Belt Drive of the frictional force transmission between band and belt wheel, also has by band and the tooth on belt wheel
It is intermeshed the toothed belt transmission of transmission.
V belt translation has simple structure, stable drive, can buffer absorbing, can transmit and move between big distance between axles and multiaxis
Power, and low cost, it is not required to lubrication, the features such as maintenance is easy, using very extensive in Modern Mechanical transmission.Friction Type Belt
It is low that transmission can overload skidding, running noise, but transmission ratio inaccuracy (sliding ratio is below 2%)；Toothed belt transmission can guarantee transmission
Synchronous but slightly worse to the absorbability of load variations, running at high speed has noise.V belt translation is in addition to transmit power, sometimes
For conveying material, the permutation for carrying out part etc..
V belt translation is usually made of driving wheel, driven wheel and the endless belt being stretched on two-wheeled, different depending on the application, and band passes
It is dynamic to be divided into general industry transmission belt, automobile transmission belt, agricultural machinery transmission belt and household electrical appliance transmission belt.Friction
Type transmission belt divides flat rubber belting, V band and particular band (V-ribbed belt, round belt) etc. according to the different of its cross sectional shape again.
Currently, the Chinese patent function of Publication No. CN2084130U discloses a kind of planet type gearing with belt, it
On the driven wheel of general belt driver, circumferentially increase several planetary gears, on the driven wheel of general belt driver, edge
Circumference is machined with positioning braking and incises, and the transposition and rotation of workpiece use primary transmission, and the power and energy of the device is only with control
" braking " or " release " of electromagnetic brake processed.
Although this planet type gearing with belt simply cleverly solve the workpiece rotation encountered in the Automation Design and
Transposition problem, but after belt pulley is long using the time, belt is easy relaxation, and transmission ratio precision further decreases at this time, holds
Easily skid in transmission process.
