It should be noted that in the present embodiment, can use and a positioning is set between two adjacent grooves 212
The design of pin-and-hole 211 or second keyway 213, passes through above-mentioned interval setting, it is ensured that one-way clutch body 21 is being rotated
When uniform force, and then slow down the serious situation of the concentrated wear because of caused by the unbalance stress of one-way clutch body 21, increase is super
The more service life of clutch.
Below in conjunction with the accompanying drawings, briefly explain the assembling process of the freewheel clutch and used cooperatively with hydraulic motor
The course of work.
1, the assembling process of freewheel clutch.
First, Qie Jin mechanisms 22 are arranged on one-way clutch body 21, specifically, in the present embodiment, member will be compressed
Part 222 is (for example：Compression spring) be arranged on groove 212 deep trouth position and with the roller installed in the shallow slot position of groove 212
221 contacts, wherein, when installing roller 221, the axis direction of roller 221 is parallel with the axis direction of one-way clutch body 21.
Then, the multiple one-way clutch 2 for installing Qie Jin mechanisms 22 are passed through into the cooperation of alignment pin and dowel hole 211
It is fixed together, and is sleeved on axle sleeve 1.Wherein, the quantity of one-way clutch 2 can according to the actual requirements (for example：Carrying is needed
Ask) adjust.
Finally, position-limit mechanism 3 is arranged on axle sleeve 1, completes the assembling of freewheel clutch.Wherein, in the present embodiment,
First positioning sleeve 31 can be sleeved on axle sleeve 1, then by the way that the cooperation of shaft end ring 32 and jump-ring slot 12 is installed, to prevent
Axial movement of the one-way clutch 2 along positioning sleeve 31.
2, the course of work that freewheel clutch is used cooperatively with hydraulic motor.
Hydraulic motor starts to rotate in the presence of hydraulic oil, and the output shaft of hydraulic motor drives the axle sleeve 1 being secured to
Rotate, when axle sleeve 1 is rotated, the shallow slot position for driving the roller 221 of Qie Jin mechanisms 22 to be moved in groove 212, and will it is unidirectional from
Clutch body 21 and the wedging clamping of axle sleeve 1 so that one-way clutch body 21 is rotated with axle sleeve 1, meanwhile, also drive and multiple unidirectional
The pinion rotation that clutch body 21 is fixed, finally, the bull gear drive that little gear driving is engaged.
The gear of same gear wheel is driven to pass in the multiple little gears of multiple fluid motor-drivens, and by multiple little gears
In dynamic system, when in multiple little gears, there is the rotating speed of a little gear very fast, the rotating speed of its drive gear wheel also accelerates, together
When, other little gears that canine tooth wheel drive is engaged make their rotating speed also accelerate, now, are fixed with these little gears
The rotating speed of one-way clutch body 21 exceedes the rotating speed of its supporting axle sleeve 1, and the roller 221 of Qie Jin mechanisms 22 is in one-way clutch body
Deep trouth position in groove 212 is moved under 21 drive so that one-way clutch body 21 and the de-chucking state of axle sleeve 1, unidirectionally
Clutch body 21 will not propeller shaft sleeve 1 rotate with it, and then the rotating speed of output shaft of hydraulic motor is slower than and is arranged on
The rotating speed of little gear on output shaft.
In addition, when one of hydraulic motor rotary speed is very fast, it may appear that the output of the slower hydraulic motor of other rotating speeds
Bearing carries reduction (because now not needing driving pinion to rotate), while the output shaft of the faster hydraulic motor of this rotating speed
Carrying can increase (because total bearing capacity of these hydraulic motors is constant).When the output shaft of the faster hydraulic motor of rotating speed
Carrying increase after, driving the pressure of the hydraulic oil needed for the hydraulic motor can increase so that enter the hydraulic pressure of the hydraulic motor
Oily flow is reduced, and then the hydraulic motor rotary speed is declined；Meanwhile, the slower hydraulic motor of rotating speed holding due to its output shaft
Reduction is carried, driving the pressure of the hydraulic oil needed for these hydraulic motors can reduce so that enter the hydraulic oil of these hydraulic motors
Flow increase, and then the rotating speed increase of these hydraulic motors, the output rotating speed of these last hydraulic motors reach identical, reality again
A kind of existing dynamic equilibrium, and then the high pulling torque transmission of gear train assembly is realized, at the same time it can also drive this without extra
The hydraulic oil of a little hydraulic motors increases the flow servo control device of hydraulic oil.
The embodiment of the present invention by constituted by axle sleeve, alignment pin, multiple one-way clutch and position-limit mechanism surmount from
Clutch, wherein, one-way clutch includes the Qie Jin mechanisms for being used to realize single-direction transmission between one-way clutch and axle sleeve, at this
Freewheel clutch is applied to gear train assembly (system that employs the multiple little gears of multiple fluid motor-drivens, then by these
The synchronous same gear wheel of driving of little gear) in when, the output shaft for the hydraulic motor fixed with axle sleeve can be made and be sleeved on many
Realize that single-direction transmission (exports rotating speed when being faster than little gear rotating speed, output shaft at once between little gear on individual one-way clutch
Driving pinion is rotated；When output rotating speed is slower than little gear rotating speed, output shaft is with little gear with respective rotational speed), enter
And make it that the gear wheel in the gear train assembly will not be influenceed by the asynchronous rotation of little gear, and then cause in the gear
In transmission system, increase the flow servo control device of hydraulic oil without the extra hydraulic oil to drive these hydraulic motors, both
The manufacturing cost of the gear train assembly can be saved, the structure of the gear train assembly can be simplified again, increases gear drive
The stability of system work.Wherein, the one-way clutch number in the freewheel clutch can be adjusted according to actual needs, can be with
Different carrying demands are met, these one-way clutch are fitted together by the cooperation of dowel hole and alignment pin, assembling side
Formula is easy, it is easy to dismounting assembling.In addition, the overrun clutch structure is simple, with low cost, easy to loading and unloading, dependable performance, have
Stronger practicality.
