Embodiment
The structural principle and operation principle of the present invention are described in detail below in conjunction with the accompanying drawings：
Refer to Fig. 1 and 2, the present invention be used for machinery handwheel clutch 10 include a handwheel fixed cell 20 and one from
Close unit 30.
Handwheel fixed cell 20 has an axle sleeve 21 and two nuts 25, and axle sleeve 21 therein is for being sheathed on a hand wheel shaft
12 (as shown in Figure 3).The two ends of axle sleeve 21 have an external thread part 22 respectively, moreover, the outer peripheral face of axle sleeve 21 has an outer shroud
Teeth portion 23, outer circular tooth part 23 is between two external thread part 22；Each spiral shell of nut 25 is located at the external thread part 22 of axle sleeve 21, borrows
This, when axle sleeve 21 be sheathed on hand wheel shaft 12 after nut 25 is locked again, you can allow axle sleeve 21 to be fixed together with hand wheel shaft 12.
In addition, the external thread part 22 of axle sleeve 21 also has four profile grooves 24 (as long as actually at least one), by profile groove 24
Set, the external thread part 22 of axle sleeve 21 can further produce radial deformation after the locking of nut 25, axle sleeve 21 is increased
With the fixed effect between hand wheel shaft 12.
Clutch unit 30 has a clutch part 31, and clutch part 31 is arranged (as shown in Figure 3) and by one with for taking turns 14 on the other hand
Flat key 32 is fixed together with handwheel 14, in addition, clutch part 31 has a set of hole 33, clutch part 31 is sheathed on axle by set hole 33
Set 21 so that clutch part 31 can be along the axially opposing axle sleeve 21 of axle sleeve 21 in a first position P1 (as shown in Figure 3) and one the
Displacement between two position P2 (as shown in Figure 4).Clutch part 31 has an inner ring teeth portion 34, hole of the inner ring teeth portion 34 located at set hole 33
Wall, when clutch part 31 is located at first position P1 as shown in Figure 3, the inner ring teeth portion 34 of clutch part 31 and the outer shroud tooth of axle sleeve 21
It is mutually disengaged between portion 23, when clutch part 31 is located at second place P2 as shown in Figure 4, the inner ring teeth portion 34 of clutch part 31 is nibbled
It is connected to the outer circular tooth part 23 of axle sleeve 21.Again as shown in figure 3, being provided with a bearing 35 between clutch part 31 and axle sleeve 21, work as clutch part
31 be located at first position P1 when, clutch part 31 can freely be rotated by bearing 35 relative to axle sleeve 21.In addition, clutch unit 30 also has
There are a return springs 36, a retainer ring 37, and a loose collar 38, return springs 36 are sheathed on axle sleeve 21 and positioned at clutch
In the set hole 33 of part 31, retainer ring 37 is sheathed on axle sleeve 21 and is connected to one end of return springs 36 so that the quilt of retainer ring 37
36 ejections of return springs and be close proximity to a C-shaped clasp 39 for being fixed on axle sleeve 21, loose collar 38 is sheathed on axle sleeve 21 and supported
It is connected to the other end of return springs 36 so that loose collar 38 is reset 36 ejections of elastic component and is close proximity to the interior of clutch part 31
Circular tooth part 34.
From said structure, when handwheel 14 to be allowed can drive hand wheel shaft 12 to rotate, first by clutch part 31 from such as
First position P1 shown in Fig. 3 is pulled to second place P2 as shown in Figure 4, when clutch part 31 is located at second place P2, from
The meeting bridle joint of inner ring teeth portion 34 of component 31 is in the outer circular tooth part 23 of axle sleeve 21, and handwheel 14 now can pass through clutch part 31 and axle
Cover the bridle joint relation between 21 and drive hand wheel shaft 12 to rotate together.In addition, the mistake moved in clutch part 31 towards second place P2
Cheng Zhong, the inner ring teeth portion 34 of clutch part 31 can promote loose collar 38 simultaneously, loose collar 38 is compressed return springs 36 and is accumulated
The elastic force of return springs 36.
If release the drive connection between handwheel 14 and hand wheel shaft 12, as long as release imposes the drawing of clutch part 31
Power, clutch part 31 can by return springs 36 elastic force act on and automatically return to first position P1 as shown in Figure 3, make from
The inner ring teeth portion 34 of component 31 departs from the outer circular tooth part 23 of axle sleeve 21, consequently, it is possible to by clutch part 31 relative to axle sleeve 21
Idle running so that handwheel 14 during being turned can not timing belt wheel shaft 12 of starting rotate.
To sum up institute is old, and handwheel clutch 10 of the invention utilizes the inner ring teeth portion 34 of clutch part 31 and the outer shroud tooth of axle sleeve 21
Bridle joint relation between portion 23 reaches the clutch effect between handwheel 14 and hand wheel shaft 12, so compared with prior art, this
On the one hand invention can effectively simplify in structure and reduce processing cost and facilitate follow-up assembling, on the other hand in operation
On sufficiently stable clutch effect can be provided, and then reach the purpose of the present invention.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Various corresponding changes and deformation, but these corresponding changes and change ought can be made according to the present invention by knowing those skilled in the art
Shape should all belong to the protection domain of appended claims of the invention.
