Abstract
The utility model relates to a branch arm end structure of a swing transmission mechanism. The branch arm end structure comprises a swing branch arm, a branch arm end bushing, a ball joint bearing and a connecting base, wherein the branch arm end bushing is nested at the tail end of the swing branch arm; glue is arranged between the front end of the branch arm end bushing and the swing branch arm, the connecting base is nested outside the ball joint bearing, and the ball joint bearing is nested outside the branch arm end bushing; and the branch arm end bushing is fixed with the swing branch arm through a fastening piece. According to the branch arm end structure of the swing transmission mechanism, the branch arm end bushing is fixed by the fastening piece, and a wear-proof casing is omitted, so that the problem of loosening of the branch arm end bushing and the wear-proof casing is solved, the loosening of the ball joint bearing and the connecting base is prevented, and the conveying effect and the transmission stability are enhanced.

Background technique
In existing machinery, be typically provided with driving mechanism, the mode of the motion that driving mechanism can provide power, direction or speed change, be on purpose used by people.In driving mechanism, with swinging transmission mechanism, be most widely used, as agricultural cutter cutter device, textile manufacturing machine feed mechanism, the continuous mechanism of paper of printing machinery etc. are all applied swinging transmission mechanism.The branch arm end's structure of swinging transmission mechanism generally as shown in Figure 1, comprise and swing support arm 1, support arm end liner cover 2, wear-resistant sleeve 3, ball joint bearing 4 and connecting base 5, support arm end liner cover 2 is socketed in the end that swings support arm 1, the front end of support arm end liner cover 2 and 1 of support arm of swing are provided with glue 6, wear-resistant sleeve 3 is socketed in outside support arm end liner cover 2, ball joint bearing 4 is socketed in outside wear-resistant sleeve 3, and connecting base is socketed in outside ball joint bearing.In use, support arm end liner cover and wear-resistant sleeve easily occur loosening the branch arm end's structure of this swinging transmission mechanism, and then cause the loosening of ball joint bearing and connecting base, have affected transmission effect, transmit poor reliability.Support arm end liner cover occurs that loosening reason is: when 1. support arm end is worked, be subject to the effect of shimmy direction static load, carry out lagging motion, cause that support arm end liner cover is loosening; 2. swing support arm from support arm end liner cover because material is different, elastic modulus E is also different, swings support arm and will keep distortion consistent with support arm end liner cover, certainly leads to internal stress, initiation is become flexible.Wear-resistant sleeve occurs that loosening reason is: wear-resistant sleeve belongs to easily damaged parts, after long-time use, must become flexible.
Model utility content
The utility model object is the branch arm end's structure that the effective and swinging transmission mechanism that reliable transmission is high of a kind of transmission is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of branch arm end's structure of swinging transmission mechanism, comprise and swing support arm, support arm end liner cover, ball joint bearing and connecting base, described support arm end liner cover is socketed in the end that swings support arm, the front end of described support arm end liner cover is provided with glue with swing arm room, described connecting base is socketed in outside ball joint bearing, and described ball joint bearing is socketed in outside support arm end liner cover; Described support arm end liner cover fixes by fastening piece and swing support arm.
Preferably, described fastening piece is screw; Described screw is arranged on the end of support arm end liner cover; The axis of the axis of described screw and swing support arm in the same way.
Preferably, described fastening piece is screw and pin; Described screw and pin are arranged on the end of support arm end liner cover; The axis of the axis of described screw and pin and swing support arm in the same way.
Preferably, described screw and support arm end liner inner room are provided with pad.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The branch arm end's structure of swinging transmission mechanism of the present utility model, use fastening piece support arm end liner cover to be fixed and cancelled the setting of wear-resistant sleeve, both overcome support arm end liner and overlapped loosening problem, also solved the loosening problem of wear-resistant sleeve, prevented the loosening of ball joint bearing and connecting base, increase the effect transmitting, strengthened the stability of transmission.The branch arm end's structure of swinging transmission mechanism of the present utility model, simple in structure, reduced the number of part, when having reduced the workload of maintenance parts, reduced cost of production.
