Description
Technical Field
The utility model relates to a power takeoff technical field specifically is an input shaft location structure.
Background
With the increasing market of power takeoff devices, customers not only have higher requirements on the service performance of the power takeoff device, but also put forward higher requirements on reducing the cost of the power takeoff device.
The structure between current power takeoff input shaft and the power takeoff casing is stable inadequately, can not guarantee under the prerequisite of power takeoff service function, improves dismouting efficiency and improves product quality simultaneously.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an input shaft location structure to overcome and under the prerequisite that can not guarantee power takeoff service function among the prior art, improve dismouting efficiency and improve product quality's problem simultaneously.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an input shaft location structure, is provided with the locking plate in the draw-in groove including setting up the draw-in groove in the input shaft one end outside, the input shaft interlude sets up in the power takeoff casing, be connected with the bolt on the power takeoff casing, locking plate free end and bolted connection.
Preferably, a rubber ring is provided between the input shaft and the power take-off housing.
Preferably, the locking plate comprises a rectangular area and a semicircular area, the rectangular area and the semicircular area are integrally formed, a circular hole is formed in the locking plate, and the circle center of the circular hole is the same as that of the semicircular area.
Preferably, the circular hole is sized to match the outer diameter of the bolt.
Preferably, two corners of one side of the rectangular area far away from the circular area are provided with chamfers.
Preferably, the rectangular area is sized to fit into a slot in the input shaft.
Preferably, the locking tab is sleeved on the bolt.
Preferably, the power take-off housing on the side where the lock plate is provided with a mounting hole for a bolt.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides an input shaft location structure, locking plate one end are inlayed in the draw-in groove of input shaft, and the other end passes through the bolt and installs on the power takeoff casing, and location structure between power takeoff input shaft and the power takeoff casing passes through the locking plate to be connected like this, and the locking plate has injectd radial rotation and axial displacement between power takeoff input shaft and the power takeoff casing, under the prerequisite of guaranteeing power takeoff service function, improves dismouting efficiency and improves product quality simultaneously.

Detailed Description
The present invention will now be described in further detail with reference to specific examples, which are intended to be illustrative, but not limiting, of the invention.
As shown in fig. 1, the utility model provides an input shaft location structure, including setting up the draw-in groove in the 3 one end outsides of input shaft, be provided with locking plate 4 in the draw-in groove, input shaft 3 alternates to set up in power takeoff casing 1, be connected with bolt 5 on the power takeoff casing 1, 4 free ends of locking plate are connected with bolt 5, are provided with rubber circle 2 between input shaft 3 and the power takeoff casing 1, and locking plate 4 includes that rectangle is regional and semicircle region, and rectangle region and semicircle region integrated into one piece, it has circular hole to open on the locking plate 4, the circular hole centre of a circle is the same with the regional centre of a circle of semicircle, and circular hole size and bolt 5 external diameter phase-match, and the regional one side both corners of keeping away from circular region of rectangle are provided with the chamfer, and the regional size of rectangle is provided with the draw-in groove looks adaptation of input shaft 3, and locking plate 4 cup joints on bolt 5, and power takeoff casing 1 of locking plate 4 one side is provided with bolt 5's mounting hole.
The working principle is as follows:
the draw-in groove of input shaft 3 is inlayed to 4 one end of locking plate, and the other end passes through bolt 5 to be installed on power takeoff casing 1, and the location structure between power takeoff input shaft 3 and the power takeoff casing 1 passes through locking plate 4 to be connected like this, and radial rotation and axial displacement between power takeoff input shaft 3 and the power takeoff casing 1 have been injectd to locking plate 4.
The present power take-off has a positioning arrangement between the input shaft 3 and the power take-off housing 1 as shown in fig. 2. The positioning structure between the input shaft 3 of the power take-off and the power take-off housing 1 is connected by a screw 6, and the screw 6 is simultaneously threaded in the input shaft 3 of the power take-off and the power take-off housing 1, and limits radial rotation and axial movement between the two.
The design structure of the utility model ensures that the positioning function between the input shaft 3 of the power takeoff and the power takeoff shell 1 is not changed, the strength locking plate 4 of the part is far higher than the screw 6, thus improving the safety; meanwhile, the dismounting convenience of the locking plate 4 is higher than that of the screw 6. Under the prerequisite of guaranteeing power takeoff service function promptly, improve dismouting efficiency and improve product quality simultaneously.
Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments and application fields, and the above-described embodiments are illustrative, instructive, and not restrictive. Those skilled in the art, having the benefit of this disclosure, may effect numerous modifications to the disclosed embodiments without departing from the scope of the invention as defined by the appended claims.
