Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of motor manufacturing, and specifically relates to an assembled precision motor end cover. Background Art
[0002] The end cover is a rear cover installed behind the motor housing, commonly known as the "end cover". Whether the end cover is good or bad will directly affect the quality of the motor;
[0003] In the prior art, during the manufacturing process of precision motors, it is necessary to assemble the precision motors through component parts, and the manufacture of the precision motors is completed through assembly. The assembly parts of the existing precision motors require the use of end covers, and the bearings are installed through the end covers to encapsulate the rear end of the motor housing. The installation of the bearings on the existing end covers is just to clamp the bearings on the inner side of the end covers. This can easily lead to the loosening of the bearings during the use of the precision motor after the precision motor is assembled, thereby causing the precision of the precision motor to decrease. Therefore, we propose an assembled precision motor end cover. Utility Model Content
[0004] The utility model aims to provide an assembled precision motor end cover to solve the technical problem that the bearing of the precision motor is easy to loosen with the end cover when the precision motor is running, so as to achieve the purpose of ensuring that the bearing can run stably.
[0005] In order to solve the above technical problems, the utility model provides an assembled precision motor end cover, including a circular motor end cover body with a concave front side, a connecting slot with the same circular shape extending from the center of the recess of the motor end cover body to the back side, and a circular fixing block with an outer diameter consistent with the inner diameter of the connecting slot is installed inside the connecting slot, and then a circular bearing body with an outer diameter consistent with the inner diameter of the fixing block is installed on the inner side of the fixing block, and then a circular limiting ring is installed on the front side of the bearing body and on the inner side of the fixing block, and a semicircular retaining ring with upper and lower symmetry and opposite openings is installed on the back side of the bearing body and on the back side of the motor end cover body.
[0006] Furthermore, four connecting protrusions are equidistantly installed in a ring shape on the periphery of the motor end cover body, and circular fixing holes are installed on the front and back sides of the connecting protrusions. The motor end cover body is fixedly connected to the motor housing through the connecting protrusions and the fixing holes.
[0007] Furthermore, a semicircular mounting ring which is symmetrical up and down and has opposite openings is installed on the back of the motor end cover body, and a semicircular mounting groove is opened on the opposite side of the mounting ring, and the clamping ring is slidably connected to the mounting groove.
[0008] Furthermore, a plurality of spring members are installed inside the installation groove and on the semicircular protruding surface of the snap ring, and one end of the spring member is fixedly connected to the installation groove, and the other end of the spring member is fixedly connected to the snap ring.
[0009] Furthermore, a square sliding groove is provided on the back of the mounting ring and extends through the mounting groove, and a rectangular sliding block is installed inside the sliding groove and extends to the back. The sliding block is fixed to the clamping ring and is slidably connected to the sliding groove.
[0010] Furthermore, anti-skid pads having a size consistent with that of the sliding block are bonded to opposite sides of the sliding block, and the anti-skid pads are made of silicone material.
[0011] Furthermore, the fixing block is fixedly connected to the connecting notch, and the limiting ring is integrally formed with the fixing block.
[0012] Through the above technical solution, the fixed connection between the fixing block and the connecting groove can effectively ensure the stability of the fixing block, and after the fixing block is stable, the stability of the bearing body can be effectively guaranteed. By integrally forming the limiting ring and the fixing block, the bearing body can be effectively limited, and the matching retaining ring can effectively ensure the stability of the bearing body.
[0013] The beneficial effects of the utility model are:
[0014] 1. In the utility model, by setting the mounting ring, the mounting ring can effectively limit the bearing body, thereby ensuring the stability of the bearing body, and by the limiting ring, the bearing body can be effectively limited, thereby effectively preventing the bearing body from shaking toward the front when the precision motor is running, and by the setting of the retaining ring, the back of the bearing body can be effectively limited, and in conjunction with the limiting ring, the bearing body is clamped inside the mounting ring and cannot be loosened, thereby ensuring the precision of the precision motor.
[0015] 2. In the utility model, through the setting of the mounting ring and the mounting groove, the mounting ring and the mounting groove can effectively install the retaining ring, and the spring member can effectively support the retaining ring, so that the retaining ring can effectively limit the bearing body, and through the setting of the sliding groove and the sliding block, the sliding block can move in the sliding groove in directions away from each other, so that the retaining ring can squeeze the spring member and return to the mounting groove, thereby facilitating the end of limiting the bearing body and facilitating the removal of the bearing body for replacement.
