Description
Technical field
The utility model is related to axis pin field, specifically a kind of special axis pin of tractor.
Background technology
The load that axis pin transmits is very big, and the extrusion stress and bending stress born during the work time are also very big, in machinery
Larger extruding force can drive axis pin to be rotated relative to axle sleeve in rotation process, this will aggravate the abrasion of axis pin；Additionally, due to dragging
Machine drawing is used for field work, bears the influence of wind and weather and external dust for a long time, working environment is severe, can also aggravate axis pin
Abrasion corrosion, make axis pin rapid failure, the failure of axis pin will directly influence the realization of vehicle functions, generate working bucket compared with
It significantly swings, resistance increase, the problems such as critical altitude determined when design be not achieved, therefore, essence is carried out to axis pin
The design of the heart selects suitable structure to carry out axial and circumferential positioning to axis pin, determines suitable surface roughness, hardness and pin
Cooperation between axis and axle sleeve is after reasonably necessary, traditional axis pin is packed into, and there are gaps between plate and rod piece, it is difficult to ensure
The requirement on machining accuracy of the verticality of plate and rod piece, outer surface is all very high, nor being easy will be in rod piece load plate.
A kind of appearance of the special axis pin of tractor does not generate axial movement and rotation, to reach the mesh of axially position and anti-rotation
's.But in place of the axis pin Shortcomings in traditional stage, such as there are gaps between plate and rod piece, it is difficult to ensure plate and bar
The verticality of part, nor being easy will be in rod piece load plate.
Utility model content
The purpose of this utility model is to provide a kind of special axis pins of tractor, to solve plate and rod piece in traditional technology
Between there are gaps, it is difficult to ensure the verticality of plate and rod piece, nor be easy the problems in rod piece load plate.
To achieve the above object, the utility model provides the following technical solutions：A kind of special axis pin of tractor, including first
Axis pin thick stick part, closing panel, bearing axle sleeve, collateral support, cranked slab and oscillating bearing, the top setting of the first axis pin thick stick part
There are the second axis pin thick stick part, the top of the second axis pin thick stick part to be provided with third axis pin thick stick part, the first axis pin thick stick part, second
The outside of axis pin thick stick part and third axis pin thick stick part is provided with collateral support, and the top of the collateral support is provided with closing panel, described
Bearing axle sleeve is provided in the middle part of collateral support, the lower part of the bearing axle sleeve is provided with oscillating bearing, the third axis pin thick stick part
Top be provided with cranked slab.
Preferably, the first axis pin thick stick part and collateral support interference fit connection.
Preferably, threaded hole and through-hole are provided at the top of the first axis pin thick stick part.
Preferably, it is provided with lubricating grease between the collateral support and cranked slab.
Compared with prior art, the utility model has the beneficial effects that：The utility model can use clearance fit, convenient
Anti-rotation and axially position can be achieved at the same time in assembly or disassembly, and does not influence the intensity of axis pin and bearing, can bear prodigious circle
All tangential forces meet the requirement of tractor work, realize reliable anti-rotation and positioning, since mating surface is small, are generated to axis pin attached
Part stress is also very small, and oscillating bearing can ensure the verticality of plate and axis pin thick stick part, the essence of the flatness of end face than hole
Degree is more prone to realize, reduces difficulty of processing, and multidiameter structure directly comes to plate just solderable on the shaft shoulder, greatly carries
High welding efficiency, can reduce the cooperation precision of plate and axis pin thick stick part, again reduce difficulty of processing, when being also beneficial to welding
The assembly of plate and rod piece, axis pin thick stick part need not streak from other surfaces, protect the surface of axis pin and axle sleeve well, match
Precision is closed also to be easy to reach.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model the first axis pin thick stick part structural schematic diagram.
Fig. 3 is the overlooking structure diagram of the utility model.
In figure：The collateral support of 1- the first axis pin thick sticks part, 2- bearings axle sleeve, 3-, 4- cranked slabs, 5- third axis pin thick sticks part, 6- are closed

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1~3, in the utility model embodiment, a kind of special axis pin of tractor, including the first axis pin thick stick part 1,
Closing panel 8, bearing axle sleeve 2, collateral support 3, cranked slab 4 and oscillating bearing 6, the top of the first axis pin thick stick part 1 are provided with
