Technical Field

[0001] The utility model relates to the technical field of gear sleeves, in particular to a high-strength gear sleeve with high wear resistance. Background Art

[0002] The most common mining machinery is the excavator.

[0003] Excavator bucket teeth are important consumable parts on excavators. Bucket teeth fail after only 3 days (about 36 hours) of use under normal working conditions. This does not meet the requirements from both economic and usage perspectives. Such bucket teeth are generally integrally formed, made of a single material, and applicable to a single environment. Therefore, they are very limited. When changing to different sites for operation, bucket teeth that match the work area need to be replaced, which will reduce work efficiency, and the service life of a single bucket tooth is also short. Therefore, a high-strength tooth sleeve with high wear resistance is needed to protect the bucket teeth. Utility Model Content

[0034] Among them, four semicircular blocks 5 are fixedly connected to the upper surface of the gear sleeve 4. The materials of the four semicircular blocks 5 and the reinforcement block 6 are all high manganese steel. Four buffer springs 13 are fixedly connected to the inner wall of the gear sleeve 4. Dampers are arranged inside the four buffer springs 13.

[0035] Furthermore, a buffer plate 14 is fixedly connected to the rear surface of the four buffer springs 13 and the damper, the rear surface of the buffer plate 14 contacts the front end of the bucket tooth body 1, and the rear surface of the tooth sleeve 4 is fixedly connected to two fixing plates 3.

[0036] Furthermore, a first fixing slot 2 is provided on the left side of the two fixing plates 3, and the two first fixing slots 2 respectively penetrate the right side of the two fixing plates 3. The left and right sides of the bucket tooth body 1 are welded with connecting plates 9, and the opposite surfaces of the two connecting plates 9 are provided with T-shaped slide grooves 11.

[0037] Furthermore, the inner walls of the two T-shaped slide grooves 11 are slidably connected with T-shaped sliders 10 , and the opposite ends of the two T-shaped sliders 10 are fixedly connected to the inner wall of the gear sleeve 4 .

[0038] Furthermore, threaded holes 12 are provided on the rear surfaces of the two T-shaped sliders 10 and the two connecting plates 9 . The two front and rear corresponding threaded holes 12 are connected to each other, and fixing bolts 8 are threadedly connected to the threads on the inner walls of the two front and rear corresponding threaded holes 12 .

[0039] Furthermore, second fixing slots 7 are provided on both left and right sides of the bucket tooth body 1 , and the two second fixing slots 7 are arranged corresponding to the first fixing slots 2 on the left and right sides.

[0040] Furthermore, when installing the tooth sleeve 4, firstly, the tooth sleeve 4 is sleeved on the outer wall of the bucket tooth body 1, and at the same time, the two T-shaped sliders 10 are slidably connected inside the two T-shaped slide grooves 11. The two T-shaped sliders 10 and the two T-shaped slide grooves 11 play a positioning and auxiliary role in the installation of the tooth sleeve 4, thereby improving the installation accuracy and efficiency of the tooth sleeve 4. When the two T-shaped sliders 10 are pushed to the point where they cannot move, the two first fixing slots 2 correspond to the two second fixing slots 7. Then, the two fixing bolts 8 are inserted into the two threaded holes 12 through the gap between the bucket tooth body 1 and the tooth sleeve 4, and the two fixing bolts 8 are tightened by an external tool to fix the bucket tooth body 1 and the tooth sleeve 4 together. Then, the bucket tooth body 1 is fixedly installed on the excavator bucket through the two first fixing slots 2 and the two second fixing slots 7, so that the tooth sleeve 4 and the excavator are fixedly installed. The bucket is fixedly connected to the bucket, thereby improving the installation firmness of the tooth sleeve 4. When the grab bucket encounters a hard soil layer or a large number of hard stones, the tooth sleeve 4 is set to replace the bucket tooth body 1 to contact the hard stones, thereby reducing the wear of the body and increasing the service life of the bucket tooth body. By setting the reinforcement block 6, the reinforcement block 6 is made of high manganese steel and will first contact the hard soil layer or hard stone to crush the hard soil layer or hard stone to prevent the front end of the tooth sleeve 4 from encountering the hard stone and causing crushing. Through the wear resistance of the tooth sleeve 4, by setting four semicircular blocks 5, the four semicircular blocks 5 improve the compression resistance and wear resistance of the upper surface of the tooth sleeve 4. By setting four buffer springs 13 and buffer plates 14, it can be prevented from directly contacting the front inner wall of the tooth sleeve 4 during the use of the bucket tooth, causing damage to the front end of the bucket tooth and the front inner wall of the tooth sleeve 4.

[0041] Working principle: When installing the tooth sleeve 4, first sleeve the tooth sleeve 4 on the outer wall of the bucket tooth body 1, and at the same time make the two T-shaped sliders 10 slide and connect inside the two T-shaped slide grooves 11. The two T-shaped sliders 10 and the two T-shaped slide grooves 11 play a positioning and auxiliary role in the installation of the tooth sleeve 4, improving the installation accuracy and efficiency of the tooth sleeve 4. When the two T-shaped sliders 10 are pushed to the point where they cannot move, the two first fixed slots 2 correspond to the two second fixed slots 7. Then, insert the two fixing bolts 8 into the two threaded holes 12 through the gap between the bucket tooth body 1 and the tooth sleeve 4, and tighten the two fixing bolts 8 through an external tool to fix the bucket tooth body 1 and the tooth sleeve 4 together. Then, fix it to the excavator bucket through the two first fixed slots 2 and the two second fixed slots 7, so that the tooth sleeve 4 is fixed to the excavator. The bucket is fixedly connected to the bucket, thereby improving the installation firmness of the tooth sleeve 4. When the grab bucket encounters a hard soil layer or a large number of hard stones, the tooth sleeve 4 is set to replace the bucket tooth body 1 to contact the hard stones, thereby reducing the wear of the body and increasing the service life of the bucket tooth body. By setting the reinforcement block 6, the reinforcement block 6 is made of high manganese steel and will first contact the hard soil layer or hard stone to crush the hard soil layer or hard stone to prevent the front end of the tooth sleeve 4 from encountering the hard stone and causing crushing. Through the wear resistance of the tooth sleeve 4, four semicircular blocks 5 are set to improve the compression resistance and wear resistance of the upper surface of the tooth sleeve 4. By setting three buffer springs 13 and buffer plates 14, it can be prevented from directly contacting the front inner wall of the tooth sleeve 4 during the use of the bucket tooth, causing damage to the front end of the bucket tooth and the front inner wall of the tooth sleeve 4.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
