Abstract
The invention provides a locking mechanism for transmission combination or transmission separation between two transmission shafts. The locking mechanism comprises a driving shaft (1), a driven shaft (2), a locking sliding block (3), a spring (6), a matrix (10) and a bolt (13), and is capable of effectively locking the driven shaft and preventing the driven shaft from rotating during the transmission separation between the two transmission shafts. The locking mechanism is simple and reliable in structure and can be used for the occasions that the driven shaft needs long-time locking during the work of transmission shafts or machines in low-speed of revolution.
Description
Technical field
The invention belongs to technical field of mechanical transmission, more particularly, to a kind of transmission combination for two transmission between centers or biography
Move detached lockable mechanism, effective locking another one power transmission shaft when separating for two transmission between centers transmissions, when transmission combines
Allow two power transmission shaft synchronous rotaries.
Background technology
Machine operation state has the different working modes such as continuous way or batch (-type).Some machines, in the work interval time
Even if seeking slave drive axle in the case of dead electricity, also want effective locking, and operationally, solve again and remove power transmission shaft locking, main
Motion between moving axis and driven shaft will effectively be connected with power.The clutch with normally opened or normally closed type combination function can be
In the case of dead electricity, realize the separation of principal and subordinate's power transmission shaft, but for small machines or require machine operation state to be in longer lock
Only the application of time needs, and this attachment structure is usually relatively complex, relatively costly, and maintenance requirement is high.
The present invention proposes one kind and is opened by power transmission shaft itself, combines or the detached lock of transmission for two transmission between centers transmissions
Locking mechanism.
Content of the invention
It is an object of the invention to provide a kind of transmission for two transmission between centers combines or is driven detached lockable mechanism.
Effective locking another one power transmission shaft when separating for two transmission between centers transmissions, allows two power transmission shafts synchronous when transmission combines
Rotation.
The present invention employs the following technical solutions:
Brief description
Fig. 1 is driving shaft.In figure, 1-- driving shaft, 4-- active axle head inclined-plane, 8-- driving shaft connecting-type face, 11-- is actively
Axle periphery.
Fig. 2 assembles for locking driven shaft.In figure, 2-- driven shaft, 3-- locking slide block, 5-- locking slide block inclined-plane, 6-- bullet
Spring, 7-- lock groove, 9-- driven shaft connecting-type face, 10-- matrix, 12-- matrix endoporus, 13-- screw.
Fig. 3 combines assembling for power transmission shaft unblock.
Specific embodiment
Power transmission shaft lockable mechanism is made up of driving shaft 1, driven shaft 2, locking slide block 3, spring 6, matrix 10, screw 13.
As depicted in figs. 1 and 2, the driven shaft connecting-type face 9 on the driving shaft connecting-type face 8 and driven shaft 2 on driving shaft 1
Separate, locking slide block 3 in the presence of spring 6, snaps in the lock groove 7 on driven shaft 2, so that driven shaft 2 can not be rotated, be in lock
Only state.
As shown in figure 3, matrix endoporus 12 is coaxial with driven shaft 2, when power transmission shaft needs to combine, driving shaft 1 is made to enter base
Matrix endoporus 12 in body 10, under external force, active axle head inclined-plane 4 is acted on locking slide block inclined-plane 5, makes locking slide block 3
Overcome the resistance of spring 6, move up, and intercepted by driving shaft periphery 11.Driving shaft 1 continues to move to matrix endoporus 12,
So that driving shaft connecting-type face 8 is combined with the driven shaft connecting-type face 9 on driven shaft 2, complete unblock and the driving shaft of driven shaft 2
1 combination, thus realize the transmission by driving shaft 1 to driven shaft 2 of motion and power.
Driving shaft connecting-type face 8 can adopt multiple connecting-type faces such as gear with driven shaft connecting-type face 9.
Invention beneficial effect
The transmission that the present invention is used for two transmission between centers combines or is driven detached lockable mechanism, simple and reliable for structure, can
With effective locking driven shaft when two transmission between centers transmissions separate, prevent driven shaft from rotating.The present invention can be used for the slow-speed of revolution
When power transmission shaft or machine operation, driven shaft needs the occasions such as long-time locking.
