Abstract
The invention discloses a centrifugal friction coupler, comprising a casing, and a driven key shaft sleeve fixedly connected on a sidewall of the casing coaxially, which is characterized in that an axle shaft is sleeved in the clearance of the external peripheral surface of the driven key shaft sleeve in the casing; an axis end of the axle shaft extends out the other sidewall of the casing and is rolling fitted with the sidewall through a bearing; a disc body extending out in a radial direction is arranged at the central section of the external peripheral surface of the axle shaft in the casing; a plurality of arc through grooves are uniformly distributed on the surface of the disc body; a centrifugal block is movably inserted into each arc through groove on the disc body; the centrifugal block is movably connected with the disc body through a pin roll passing the arc through groove; two adjacent centrifugal blocks are connected with each other through a draught spring. The centrifugal friction coupler, has the advantage that the friction surface of the friction block absolutely escapes from the inner friction surface of the casing when the load torque passed by the driven shaft goes beyond the set value, thus avoiding the burnout of the coupler when the driven shaft is overloaded.
Description
Technical field
The present invention relates to the coupling in the machine driven system, especially relate to centrifugal type friction coupling device.
Background technique
Centrifugal type friction coupling device is usually used in connecting between original machine output shaft and the working shaft, and the moment of torsion of prime mover output is passed to working shaft.The existing deficiency of centrifugal type friction coupling device is mainly when working shaft (driven shaft) load surpasses setting value at present, centrifugal rubbing surface can not break away from the interior rubbing surface of housing fully, therefore causes sliding friction to take place between the rubbing surface in centrifugal rubbing surface and the housing and then produce high temperature to burn out coupler.
Summary of the invention
It is a kind of when the driven shaft load surpasses setting value that the object of the invention is to provide, and the rubbing surface of brake pad breaks away from the centrifugal type friction coupling device of rubbing surface in the housing automatically fully.
For achieving the above object, the present invention can take following technical proposals:
Centrifugal type friction coupling device of the present invention, it comprises housing, coaxial line is fixed in the driven key axle sleeve on described housing one sidewall; Be set with a semiaxis in the driven key axle sleeve outer circumferential face gap that is positioned at housing, the axle head of described semiaxis extends outside another sidewall of housing and rolls with this sidewall by bearing and cooperates; Be positioned at semiaxis outer circumferential face middle part the disk body structure of housing, uniformly on described disk body card offer a plurality of arc-shaped slots for extending radially outward; Activity is fitted with centrifugal respectively on the disk body that is positioned at each arc-shaped slot position, and described centrifugal bearing pin and disk body flexible connection by running through arc-shaped slot is connected by draught spring between adjacent two centrifugal.
In described housing, be positioned at described disk body both sides uniform be arranged at intervals with many to centrifugal guide plate, on every pair of centrifugal guide plate, be respectively arranged with a pair of spring top bead vertically, offer decorative pearl on top of an official cap recess respectively corresponding to described spring top bead position in the disk body bi-side.
Described each outer circumferential face of centrifugal all is compounded with the arc friction plate of being made by high-abrasive material.
When advantage of the present invention just was that the load torque that transmits when driven shaft (working shaft) surpasses setting value, the rubbing surface of brake pad can break away from the interior rubbing surface of housing fully.When driven shaft overload causes in centrifugal rubbing surface and the housing rubbing surface generation slide relative to rub or driven shaft when not changing a job condition, increase along with prime mover output power, force the spring top bead that is arranged on the described centrifugal guide plate to be separated from the decorative pearl on top of an official cap recess that is located on the described disk body bi-side, therefore, centrifugal guide plate and disk body generation angular displacement, impel the bearing pin that runs through in the disk body arc-shaped slot to move along curve bath, driving centrifugal inwardly shrinks and the interior rubbing surface of disengaging housing, thereby stopped to break away from fully because of centrifugal rubbing surface under the driven shaft overload situations the interior rubbing surface of housing, the generation that sliding friction burns out the coupler phenomenon has taken place in centrifugal rubbing surface and the housing between the rubbing surface and cause.
