Summary of the invention
The object of the invention is to propose a kind of Adjustment precision high and the friction type limit square clutch of on-line tuning can be realized.
For achieving the above object, the present invention takes following technological scheme:
This friction type limit square clutch comprises driven shaft interface, housing, driving shaft interface and the friction plate combination be made up of outside friction disc and inner attrition piece, driven shaft interface is connected to the front end of housing, driving shaft interface is in housing, outside friction disc is connected in inner walls by spline form, inner attrition piece is connected on the outer cylinder of driving shaft interface by spline form, the pressure ring be connected to by spline form in inner walls is provided with in housing and at the rear of friction plate combination, the rear end of housing is connected with the spring seat be enclosed within driving shaft interface, spring seat is circumferentially evenly distributed with spring eye, helical spring and cushion block is provided with in each spring eye, each helical spring one end is supported and cushion block, the extended spring eye of the other end supports and pressure ring, on the trailing flank of spring seat, corresponding each spring eye is provided with screw hole, adjusting screw is provided with in screw hole, adjusting screw is supported and cushion block, adjusting screw is provided with locking nut, the front end of driving shaft interface is connected with end axle, the front portion of end axle is inserted in the center hole of driven shaft interface, the center hole Spielpassung of end axle and driven shaft interface.
In described housing and the front being in friction plate combination is provided with adjustment ring, friction plate combination is clamped between described adjustment ring and described pressure ring.
The rear portion in the hole of described driven shaft interface has ring-shaped step, and the front end of end axle is connected with end cap, and end cap is in the front side of ring-shaped step.
Described housing some radiation holes have been evenly arranged.
The present invention has following good effect: 1, in the present invention, each helical spring is equipped with an adjusting screw, helical spring is respectively regulated by adjusting screw, so the screw-down torque of adjusting screw is little, only need to use general little torque wrench can regulate adjusting screw, conveniently carry out on-line tuning on a production line.2, the present invention adopts and puts helical spring structure week and provide impacting force, makes friction plate uniform force, not easily occurs friction plate eccentric wear phenomenon.When adjusting identical decrement, adopting and week putting helical spring structure, the change of its impacting force is less, and therefore its Adjustment precision is higher.3, helical spring of the present invention is arranged in the spring eye of spring seat, and helical spring is not easily deviate from, and Safety performance is good.4, the present invention is simple and compact for structure, and required space is little.5, driving shaft interface of the present invention and driven shaft interface have versatility.6, helical spring of the present invention is between pressure ring and cushion block, and without relative movement between pressure ring and cushion block, helical spring does not bear torsion, so helical spring is not fragile.
