Abstract
The utility model discloses a get shaft coupling of using on tractor driver's arm, including a shaft body, the shaft hole has been seted up in the axis body, be provided with the keyway on the shaft hole, the locating hole has been seted up on the axis body, be provided with the cushion collar in the locating hole, the axis body terminal surface is provided with the oilhole, oilhole and shaft hole and locating hole intercommunication, the bloop has been seted up on the axis body, be provided with the fine cotton stick of glass in the bloop. The advantage is: the utility model has the advantages of simple structure, cushion collar in the locating hole can let it effectively slow down the impact force that the cylinder axle received when using with the cylinder shaft fit, lengthens its life, and the fine cotton stick of the glass on the axis body can absorb the produced noise of axis body during operation, effectively reduces noise pollution.
Description
Technical field
The utility model belongs to the component technology field on extractor, especially relates to the coupling on a kind of extractor arm.
Background technique
At present, the rotary cylinder on extractor arm is connected by coupling mostly with rotating shaft, allows transmission of power on rotary cylinder in rotating shaft by the effect of coupling.Cylinder axis on existing coupling and rotary cylinder with the use of time, because the impact force between it is comparatively large, often cause cylinder axis rupture, this causes larger impact to using; Be exactly that in use the produced noise of existing coupling is comparatively large in addition, easily cause noise pollution; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides the coupling on a kind of extractor arm, it have structure simple, effectively can slow down the impact force suffered by cylinder axis and effectively reduce the feature of noise.
To achieve these goals, the technological scheme that the utility model adopts is: the coupling on a kind of extractor arm, comprises axis body, offers axis hole in described axis body, and described axis hole is provided with keyway; Described axis body offers positioning hole; Be provided with cushion collar in described positioning hole, described axis body end face is provided with oilhole, and described oilhole is communicated with axis hole and positioning hole; Described axis body offers bloop, in described bloop, is provided with glass swab stick.
The surrounding of described positioning hole is distributed with two glass swab sticks.
Described cushion collar is polyurethane sleeve.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, cushion collar in positioning hole can be allowed to condition at cylinder axis with the use of time effectively slow down impact force suffered by cylinder axis, extend its working life; And glass swab stick on axis body can absorption axes body running time the noise that produces, effectively reduce noise pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, as shown in Figure 1: the coupling on a kind of extractor arm, comprises axis body 10, offers axis hole 11 in axis body 10, and axis hole 11 is provided with keyway 12, axis hole 10 and keyway 12 can with the cylinder axis collaborations on rotary cylinder.Also offer positioning hole 13 in the side of axis body 10, positioning hole 13 is six, convenient like this with cylinder axis with the use of; In positioning hole 13, be provided with cushion collar 20, cushion collar 20 is selected as polyurethane sleeve, and it effectively can slow down the impact force suffered by cylinder axis, prevents it from use rupturing.The arc surface of axis body 10 offers oilhole 14, and oilhole 14 is communicated with axis hole 11 and positioning hole 13, so conveniently adds oiling agent.Around each positioning hole 13, be distributed with two bloops, be provided with glass swab stick 30 in bloop, the noise produced when glass swab stick 30 can absorb axis body 10 operation, effectively reduces noise pollution.
