Description

Technical Field

[0001] The utility model relates to the technical field of half-axle sleeves, in particular to a half-axle sleeve for a tractor. Background Art

[0002] The half-axle sleeve is an important part of the automobile drive axle assembly. It is integrated with the drive axle housing to fix the axial relative position of the left and right drive wheels, and together support the frame and the mass of the assemblies thereon. At the same time, it withstands the road reaction force and torque transmitted from the wheels when the car is running, and transmits them to the frame through the suspension. Therefore, the half-axle sleeve bears huge loads both in the axial and radial directions, and the half-axle sleeve is very prone to bending during use.

[0003] However, the existing half-axle sleeve body and flange are integrally formed, so they are generally replaced as a whole during maintenance. The undamaged flange cannot be used any more, resulting in a waste of resources and increasing the cost of use. Therefore, a half-axle sleeve for a tractor is proposed. Utility Model Content

[0017] 1. Compared with the prior art, the half-axle sleeve for the tractor is provided with an installation groove, a clamping groove, a clamping strip, an installation hole, a positioning hole and a locking bolt. When the sleeve is damaged and needs to be replaced, the two locking bolts are rotated counterclockwise. When one end of the locking bolt is separated from the positioning hole on one side of the sleeve body, the sleeve body is pulled outward to remove the sleeve body for replacement. When installing a new sleeve, one end of the sleeve body is inserted into the installation groove, and the two clamping strips are inserted into the clamping groove. Then, the two locking bolts are installed in the installation hole, and the locking bolts are rotated clockwise to insert one end thereof into the positioning hole to realize the positioning of the sleeve body, that is, the installation of the sleeve body is completed. When the detachable sleeve is damaged, the damaged part can be replaced separately without replacing the flange as a whole, which can effectively reduce the use cost.

[0018] 2. Compared with the prior art, the half-axle sleeve for the tractor is provided with a plurality of reinforcing strips, which are fitted with the inner wall of the sleeve body, thereby improving the overall strength of the sleeve and increasing the load weight of the sleeve body.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 4 The utility model provides a half-axle sleeve for a tractor: it comprises a flange 1, a mounting seat 2 is fixedly provided on one side of the flange 1, a mounting groove 3 is provided on one side of the mounting seat 2, mounting holes 5 are provided on both sides of the mounting seat 2, a locking bolt 6 is provided in the mounting hole 5, the mounting hole 5 is stepped, the stepped mounting hole 5 can accommodate the head of the locking bolt 6 to prevent the head of the locking bolt 6 from protruding and affecting the normal use of the equipment, the inner wall of the mounting hole 5 is provided with a thread, the thread of the inner wall of the mounting hole 5 of the locking bolt 6 is adapted, a sleeve body 8 is provided in the mounting groove 3, two positioning holes 10 are provided on the outside of the sleeve body 8, the positioning holes 10 are adapted to the locking bolt 6, the positioning holes 10 and the locking bolt 6 are used in combination, the sleeve body 8 can be locked and fixed, and the sleeve body 8 is provided with a texture 11 on the outside;

[0027] Reference Figure 2 In order to achieve the purpose of reinforcement, two clamping grooves 4 are provided on the inner wall of the installation groove 3, and two clamping strips 9 are fixedly provided on the outside of the sleeve body 8. The clamping strips 9 and the clamping grooves 4 are adapted to each other. The combination of the clamping strips 9 and the clamping grooves 4 can achieve the limitation of the sleeve body 8, and prevent the sleeve body 8 from slipping or rotating when one end of the locking bolt 6 is separated from the positioning hole 10, so as to achieve the purpose of reinforcement;

[0028] Reference Figure 2 In order to improve the overall strength of the casing, a plurality of reinforcing strips 7 are fixedly provided on one side of the mounting seat 2. The number of the reinforcing strips 7 is eighteen, and the eighteen reinforcing strips 7 are arranged in a circular equidistant array. The length of the reinforcing strips 7 is fifteen centimeters. The reinforcing strips 7 are made of stainless steel, and the reinforcing strips 7 are in contact with the inner wall of the casing body 8. The reinforcing strips 7 are in contact with the inner wall of the casing body 8, thereby improving the overall strength of the casing and increasing the load weight of the casing body.

[0029] Working principle: When the sleeve body 8 is deformed and damaged and the flange 1 is not damaged and the sleeve needs to be replaced, first rotate the two locking bolts 6 counterclockwise, and the two ends of the locking bolts 6 move away from each other. When one end of the locking bolt 6 is out of the positioning hole 10 on one side of the sleeve body 8, pull the sleeve body 8 outward, and the sleeve body 8 drives the clamping strip 9. When the clamping strip 9 is completely out of the card slot 4, the sleeve body 8 can be removed and replaced. When installing the sleeve body 8, insert one end of the sleeve body 8 into the installation slot 3, and insert the two clamping strips 9 into the card slot 4, and then install the two locking bolts 6. It is installed in the installation hole 5, and the locking bolt 6 is rotated clockwise to insert one end of it into the positioning hole 10 to realize the positioning of the sleeve body 8. The matching use of the clamping strip 9 and the clamping groove 4 can realize the limitation of the sleeve body 8 to prevent the sleeve body 8 from slipping or rotating when one end of the locking bolt 6 is separated from the positioning hole 10, which plays a reinforcement role. The reinforcing strip 7 fits with the inner wall of the sleeve body 8, which can improve the load strength of the sleeve body 8. The detachable sleeve body 8 can replace the damaged part separately when it is damaged, without the need to replace the flange 1 as a whole, which can effectively reduce the cost of use.
