Description
Technical Field
The utility model relates to a shaft sleeve positioning structure.
Background
The shaft sleeve positioning structure in the prior art is shown in figure 1: bearing 11, shaft sleeve 12, key 13, shaft 14, stop groove 15, round nut 16 and stop washer 17. The working principle is as follows: referring to fig. 1, a key 13 is attached to a shaft 14, a sleeve 12 is attached to the shaft 14 in cooperation with the key 13, and a bearing 11 is attached to the sleeve 12. A stop washer 17 and a round nut 16 are respectively installed at the left side of the shaft housing. The circumferential positioning of the shaft sleeve is completed through the working mechanism of the key, the stop sheet of the stop washer is clamped in the stop groove 15 on the shaft 14, and the axial positioning of the shaft sleeve and the looseness prevention of the round nut are realized by matching with the round nut. However, the prior structure has the following defects: the assembly parts are many: the key, the round nut, the stop washer and other parts are required to be assembled, the number of the parts is large, and the assembling and the disassembling are complicated. The cost is wasted: in order to install the round nut and the stop washer, the size of the shaft needs to be increased, and a key groove and a stop groove need to be machined on the shaft, so that the material is wasted, and the working procedure is increased. Therefore, improvement of the existing shaft sleeve positioning structure is needed.
Disclosure of Invention
The utility model aims at guaranteeing under the normal moving prerequisite, simplify axle sleeve installation procedure, reduce the assembly part, reduce the cost and the processing of axle, improve production efficiency. The utility model relates to a shaft sleeve location structure, including bearing, axle sleeve, axle, organism, its characterized in that: the periphery of the front end of the shaft is provided with a positioning hole, the periphery of the shaft sleeve is provided with a shaft sleeve hole, the shaft sleeve is sleeved at the front end of the shaft and is fixed on the shaft by a positioning pin in the positioning hole of the shaft, the top end of the positioning pin is inserted into the positioning hole, the outer side of the shaft sleeve is embedded with a bearing, the inner ring of the bearing is embedded with the shaft sleeve, and the outer ring of the bearing is embedded with the machine body. The utility model has the advantages that cancel key and round nut, lock washer structure, at epaxial and the axle sleeve preformed hole, utilize the locating pin to carry out the axle sleeve location, simple structure, simple to operate.

Detailed Description
A shaft sleeve location structure in the figure comprises a bearing 1, a shaft sleeve 2, a shaft 3 and a machine body 4, and is characterized in that: the periphery of the front end of the shaft is provided with a positioning hole 5, the periphery of the shaft sleeve is provided with a shaft sleeve hole 6, the shaft sleeve is sleeved at the front end of the shaft and is fixed on the shaft by a positioning pin 7 positioned in the positioning hole of the shaft, the top end of the positioning pin is inserted into the positioning hole, the outer side of the shaft sleeve is embedded with a bearing, the inner ring of the bearing is embedded with the shaft sleeve, and the outer ring of the bearing is embedded with the machine body.
The working principle is as follows: as shown in figure 2, the shaft sleeve is arranged on the shaft, a positioning hole is reserved on the shaft, a shaft sleeve hole is reserved on the shaft sleeve, and the positioning pin is inserted into the shaft sleeve hole and the positioning hole. The bearing is arranged on the shaft sleeve, and the bearing inner ring covers the shaft sleeve hole on the shaft sleeve. The positioning pin not only plays an axial positioning role, but also plays a circumferential positioning role, thereby achieving two purposes at one stroke. Meanwhile, the positioning pin is jointly positioned by the inner ring of the bearing, the shaft sleeve hole and the positioning hole, and cannot fall off.
The utility model discloses cancellation key and round nut, lock washer structure, at epaxial and the axle sleeve preformed hole, utilize the locating pin to carry out the axle sleeve location, simple structure, simple to operate. The parts are simplified after the improvement, the number of the parts is less than that before the improvement, the assembly steps are reduced, the assembly period of the parts is shortened, and the structure is simple. After the improvement, the length of the shaft is reduced, the machining amount of parts is small, and the material cost and the machining cost are saved.
