Background technique
At present, a lot of clutches all are clutch or the wheeled clutches of belt that adopts friction type, and the structure of these two kinds of clutches is more complicated all; Structural member is also many; If use on the miniature Motor Vehicle or during agricultural cultivated machine, the clutch of friction type is easy to generate and skids, scaling loss, the wheeled clutch reliable transmission property of belt is not fine; Thereby influenced on the miniature Motor Vehicle or the normal use of agricultural cultivated machine; Influence people's work, and these two kinds of clutches cost higher relatively, also be that people do not afford to do.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, reliable transmission is steady, cost is low ball positive clutch.
The utility model is achieved in that
A kind of ball positive clutch; Rotary bearing, return spring, ball-head cover, output sprocket, input gear, rotary bearing from left to right are installed on the transmission shaft in proper order; Cooperate on the external cylindrical surface in described ball-head cover left side thrust ball bearing is installed; The right-hand member inner surface radial direction of ball-head cover is to being outside equipped with the stop bit annular groove that prevents the steel ball play; The right side inner cylindrical surface of ball-head cover matches with the external cylindrical surface of output sprocket left end, circumferentially is evenly equipped with several through holes on the sidewall of the output sprocket of cooperation place, is equipped with the clutch steel ball in each through hole; The corresponding groove that is provided with described through hole on the transmission shaft of through hole inboard is provided with the holddown spring that holds out against the clutch steel ball in the groove.
The right-hand member outside of above-mentioned thrust ball bearing with flat seat is provided with stirs the shift fork that thrust ball bearing with flat seat moves.
The stop bit annular groove of above-mentioned ball-head cover is with after described through hole aligns, and described steel ball can contact with stop bit annular groove madial wall after breaking away from groove under the effect of holddown spring, and the realization output sprocket separates with transmission shaft.
Be provided with wearing bush between above-mentioned output sprocket and the transmission shaft.
Be connected through spline between above-mentioned input gear and the transmission shaft.
The internal gear of above-mentioned input gear for being meshed with power gear.
The rotary bearing of above-mentioned transmission shaft right-hand member is provided with bearing cap.
The utility model is compared the outstanding advantage of existing technology:
1, the power of the utility model is imported from power gear, drives the input gear, and the input gear drives transmission shaft under the effect of spline; The clutch steel ball is pressed in the groove on transmission shaft surface; Combine with the through hole on the output sprocket, drive output sprocket and rotate, steadily reliable in the rotation process; Can not occur skidding, this moment, output sprocket and transmission shaft were in bonding state.Under the fork effect that utilizes external force, make ball-head cover to left movement through thrust ball bearing with flat seat, the steel ball that is pressed in the transmission shaft groove is upspring under the effect of pressure spring, breaks away from groove, reaches separating of output sprocket and transmission shaft this moment.
2, the utility model is simple in structure, and cost is low, is useful on miniature Motor Vehicle or the agricultural cultivated machine.
Description of drawings
