Abstract
The utility model relates to a connection device, in particular to a hydraulic system coupler. The hydraulic system coupler comprises a convex wheel and a concave wheel which are nested mutually, and is characterized in that a flexible polyester spline is disposed at a connection portion of the convex wheel and a groove of the concave wheel. The hydraulic system coupler has the advantages that the flexible polyester spline is even in stress in working, vibration of the coupler is avoided, coaxiality of the coupler is guaranteed, working efficiency of a gear pump is improved, and the safety factor is largely enhanced.
Description
Technical field
The utility model relates to a kind of connection set, is specifically related to a kind of hydraulic system coupling.
Background technique
Adopt coupling to connect between the motor of hydraulic system and the gear pump, the still present common rigid coupling that adopts, promptly coupling becomes flexible but the bolt connection is easy through bolt, causes damage easily, is unfavorable for maintenance.Therefore, slowly bring into use protruding, recessed coupling of taking turns form, but also can often occur when moving shaking and the phenomenon of poor fit.
The model utility content
According to the deficiency of above existing technology, the utility model technical problem to be solved is: a kind of hydraulic system coupling is provided, can avoids coupling vibrations to occur in when operation, and the cam of coupling and recessed the wheel can no-floats.
The described hydraulic system coupling of the utility model comprises mutually nested cam and recessed the wheel, and the position of cam and recessed contact grooves of taking turns is provided with the flexible polyester spline.
Wherein, preferred big or small consistent with groove of flexible polyester spline.
The beneficial effect of the utility model is: the flexible polyester spline is stressed during work has evenly avoided the vibration of coupling, has guaranteed the coaxality of coupling, thereby improved the working efficiency of gear pump that safety coefficient improves greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, cam 2, recessedly take turns 3, groove 4, flexible polyester spline.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
As shown in Figure 1, the described hydraulic system coupling of the utility model comprises that mutually nested cam 1 takes turns 2 with recessed, and cam 1 is provided with flexible polyester spline 4 with recessed 2 the groove 3 contacted positions of taking turns.
Wherein, flexible polyester spline 4 and groove 3 is big or small consistent.
The utility model flexible polyester spline 4 when work is stressed even, has avoided the vibration of coupling, has guaranteed the coaxality of coupling, thereby improved the working efficiency of gear pump that safety coefficient improves greatly.
Claims (2)
1. a hydraulic system coupling comprises mutually nested cam and recessed the wheel, it is characterized in that the position of cam and recessed contact grooves of taking turns is provided with the flexible polyester spline.
2. hydraulic system coupling according to claim 1 is characterized in that the big or small consistent of flexible polyester spline and groove.
