Description
Technical field
Decelerator field is the utility model is related to, specially a kind of Gear Planet Transmission shifter.
Technical background
Gear Planet Transmission be widely used in engineering machinery, building machinery, ship machinery, petroleum machinery, chemical machinery with
Mining machinery etc..Existing hoisting mechanism, walking mechanism, power are first-class to be not implemented more speed shifts, have impact on work effect
Rate.
For example, the Gear Planet Transmission hoisting mechanism used in autocrane, does not have gear shift function, it is still a speed, because
This, below empty hook, below lifting or underloading, lifting when, speed can not change, and have impact on the operating efficiency of hoisting mechanism, if
Accelerate speed when suspension hook decentralization or lifting in controllable velocity interval, hoisting mechanism is when underload and empty hook work
Efficiency will greatly improve.At present, the method for the small object of autocrane solution lift up rapidly weight is：Increase a secondary volume
Mechanism is raised, i.e., the secondary hoisting mechanism of usually said crane, the steel wire rope multiplying power of secondary hoisting mechanism is a multiplying power, and purpose is exactly
When lifting by crane light weight, higher lifting speed is obtained.
For another example, when running into the probing layer of different geology, stake machine is moved with Gear Planet Transmission unit head, churning driven with Gear Planet Transmission
The Gear Planet Transmission drive mechanism of power head, no-dig directional driller, it is impossible to realize gear shift so as to change output speed, have impact on work
Make efficiency.
For another example, the driving force required for walking mechanism travels on different road surfaces differs, such as：In level road
Upper traveling is smaller than the resistance when being travelled on ramp, it should top gear operation is changed to, to improve the travel speed of vehicle.In addition,
Due to no clutch, so when vehicle needs to tow, high speed hauling can not be realized.
In hoisting machinery, because suspension hook has certain weight, so, either hoisting heavy is again without a lift heavy
Thing, the gear shift of hoisting mechanism is band load gear shift, and does not allow suspension hook to have roll-off in gearshift procedure, more not in
There is phenomenon out of supply in the course of work, this allows for realizing that the gear shift of the mechanism is more difficult.
