A base for a commutator

Abstract

This application provides a commutator base, belonging to the field of commutator technology. The commutator base includes a base body, with several positioning grooves formed on one side wall of the base body. Commutator segments are inserted into each of these positioning grooves. By forming these positioning grooves on one side wall of the base body, and installing T-shaped inserts on each of the commutator segments, the T-shaped inserts are evenly distributed onto the outer wall of the base body. A positioning ring is screwed to one side wall of the base body, allowing the positioning ring to press against the side walls of the T-shaped inserts, thus fixing the T-shaped inserts and ultimately securing the commutator segments to the outer wall of the base body for easy installation and removal. Furthermore, by forming several annular heat dissipation grooves on the outer wall of the base body, and connecting the positioning grooves to these grooves, the heat dissipation effect on the commutator segments is improved during the rotation of the base body.

Description

Technical Field

[0001] This application relates to the field of commutators, and more specifically, to a commutator base. Background Technology

[0002] The commutator is the core component of a DC motor, and its performance directly affects the motor's efficiency, lifespan, and operational stability. The commutator base is used to support the commutator segments, and the rotation of the commutator base drives the commutator segments to rotate. The existing commutator segment mounting structure involves bonding the commutator segments to the outer wall of the base. However, if one of the commutator segments is damaged, the entire base needs to be replaced, which is inconvenient for replacing the commutator segments and results in high material consumption for the base. To address these issues, we propose a new commutator base. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a commutator base, which aims to improve the problem of inconvenient replacement of existing individual commutator segments.

[0004] This application provides a commutator base, including a base body. A plurality of positioning grooves are formed on one side wall of the base body, and commutator segments are inserted into each of the positioning grooves. A positioning ring is detachably connected to one side wall of the base body, and the positioning ring presses against one side wall of the plurality of commutator segments.

[0005] In one specific implementation, a plurality of the commutator segments are arranged at equal intervals, and all of the plurality of the commutator segments are attached to the outer wall of the base body.

[0006] In one specific implementation, the plurality of positioning slots are T-shaped, and a T-shaped plug is fixedly installed on each of the plurality of commutator segments. The plurality of T-shaped plugs are respectively inserted into the plurality of positioning slots, and the positioning ring presses against one end sidewall of the plurality of T-shaped plugs.

[0007] In one specific implementation, an annular assembly groove is provided on one side wall of the base body, and a plurality of positioning grooves are provided on the annular assembly groove, and the positioning ring is sleeved on the annular assembly groove.

[0008] In one specific implementation, a mounting ring is fixedly connected to one end sidewall of the positioning ring, the mounting ring is fitted against one end sidewall of the base body, and a plurality of mounting blocks are fixedly installed on the inner wall of the mounting ring, and the plurality of mounting blocks are screwed to one end sidewall of the base body.

[0009] In one specific implementation, a screw passes through each of the mounting blocks, and the screw is threaded to one end sidewall of the base body.

[0010] In one specific implementation, the mounting block has a mounting hole, and one end of the base body has a threaded hole. The screw passes through the mounting hole and is connected to the threaded hole.

[0011] In one specific implementation, a plurality of annular heat dissipation grooves are formed on the outer wall of the base body, and the positioning groove is connected to the plurality of annular heat dissipation grooves.

[0012] The beneficial effects of this application are as follows: By opening several positioning grooves on one side wall of the base body, and installing T-shaped blocks on several commutator segments, the T-shaped blocks are inserted into the positioning grooves, so that several commutator segments are evenly distributed on the outer wall of the base body. The positioning ring is screwed to one side wall of the base body, so that the positioning ring can press on the side wall of several T-shaped blocks to fix the T-shaped blocks, thereby fixing the commutator segments to the outer wall of the base body, so as to facilitate the installation and removal of the commutator segments. By opening several annular heat dissipation grooves on the outer wall of the base body, and the positioning grooves are connected to the annular heat dissipation grooves, the heat dissipation effect of the commutator segments is improved during the rotation of the base body.

Detailed Implementation

[0016] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0017] Please see Figure 1-7 This application provides a commutator base, including a base body 10. Specifically, a shaft hole is provided in the middle of the base body 10. The base body 10 is made of insulating material. A plurality of positioning grooves 20 are provided on one side wall of the base body 10. The positioning grooves 20 are open. Commutator segments 30 are inserted into each of the positioning grooves 20. The commutator segments 30 protrude outside the base body 10. A positioning ring 40 is detachably connected to one side wall of the base body 10. The positioning ring 40 presses against one side wall of the plurality of commutator segments 30. By setting the positioning ring 40, the positioning ring 40 is used to fix the plurality of commutator segments 30. The commutator segments 30 can be disassembled and installed by removing the positioning ring 40 from one side wall of the base body 10. Furthermore, the plurality of commutator segments 30 are arranged at equal intervals. The plurality of commutator segments 30 are all attached to the outer wall of the base body 10. The pins of connecting wires are fixedly installed on the outer wall of the commutator segments 30.

[0018] See Figure 5-7 Several positioning slots 20 are T-shaped, and several commutator segments 30 are fixedly installed with T-shaped plugs 310. Several T-shaped plugs 310 are inserted into several positioning slots 20 respectively. When set, the T-shaped connection structure can limit the T-shaped plugs 310, so that the T-shaped plugs 310 can only be pulled out from one end of the positioning slot 20. The positioning ring 40 presses on one end side wall of several T-shaped plugs 310. The shape of the T-shaped plugs 310 is adapted to the positioning slots 20. The positioning ring 40 is connected to the base body 10. The positioning ring 40 can fix the T-shaped plugs 310, thereby fixing the commutator segments 30.

[0019] See Figure 4 An annular assembly groove 110 is provided on one side wall of the base body 10. Several positioning grooves 20 are provided on the annular assembly groove 110. A positioning ring 40 is sleeved on the annular assembly groove 110. In specific settings, the shape of the positioning ring 40 is adapted to the annular assembly groove 110 so that the positioning ring 40 can be slidably sleeved on the annular assembly groove 110. The annular assembly groove 110 can limit the positioning ring 40.

[0020] See Figure 3 and 4A mounting ring 410 is fixedly connected to one side wall of the positioning ring 40. The mounting ring 410 is fitted against one side wall of the base body 10. Several mounting blocks 420 are fixedly installed on the inner wall of the mounting ring 410. Each mounting block 420 is screwed to one side wall of the base body 10. Each mounting block 420 has a threaded rod 430 passing through it. The threaded rod 430 is threaded to one side wall of the base body 10. The positioning ring 40 is inserted into the annular assembly groove 110 and pressed against the T-shaped insert 310. The mounting ring 410 is fitted against one end of the base body 10. On the side wall, the screw 430 is passed through the mounting block 420 and connected to the side wall of the base body 10 to fix the mounting ring 410, thereby fixing the positioning ring 40. Furthermore, the mounting block 420 is provided with a mounting hole 440, and a threaded hole 50 is provided on one end side wall of the base body 10. The screw 430 passes through the mounting hole 440 and is connected to the threaded hole 50. Specifically, the head of the screw 430 is pressed on the mounting block 420, and the mounting block 420 is attached to one end side wall of the base body 10.

[0021] See Figure 7 The outer wall of the base body 10 is provided with several annular heat dissipation grooves 60. The positioning groove 20 is connected to the several annular heat dissipation grooves 60. During the rotation of the base body 10, the air circulation inside the several annular heat dissipation grooves 60 can be ensured through the several annular heat dissipation grooves 60, thereby improving the heat dissipation of the commutator 30.

[0022] When using this commutator base: Align and insert the T-shaped plug 310 with the positioning groove 20, and install several commutator segments 30 in sequence. After the several commutator segments 30 are inserted into the outer wall of the base body 10, insert the positioning ring 40 into the annular assembly groove 110, and at the same time, make the mounting hole 440 on the mounting block 420 correspond to the threaded hole 50. Then, pass the screw 430 through the mounting hole 440 and connect it to the threaded hole 50 to complete the installation of the commutator segments 30. One end of the commutator segment 30 is used to connect wires for use in the commutator.

[0023] It should be noted that the specific model and specifications of the commutator segment 30 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.
