Description

Technical Field

[0001] This utility model relates to the field of brushed motor technology, and in particular to a novel motor with convenient carbon brush sleeve installation. Background Technology

[0002] A brushed motor, as an electric drive device, mainly consists of a stator permanent magnet, rotor windings, and a commutator. When current flows through the carbon brushes and commutator into the rotor windings, the energized coils generate torque under the influence of the magnetic field. As the rotor rotates, the commutator automatically switches the current direction through mechanical contacts, thereby maintaining continuous power output. Carbon brushes are typically located on both sides of the commutator, specifically mounted on brush sleeves. (See attached image) Figure 7 As shown, in existing brushed motors, the carbon brush sleeve 70 is mainly fixedly installed at the commutator mounting bracket 91. The carbon brush sleeve 70 specifically has bolt connection holes 73, and a first screw 92 passes laterally through the bolt connection holes 73 to fix the carbon brush sleeve 70 to the commutator mounting bracket 91. This structural design has certain installation inconveniences. When the first screw 92 passes laterally through the bolt connection holes 73 of the carbon brush sleeve 70, it easily interferes with the second screw 93 above it. The head 921 of the first screw 92 easily hits the tail 931 of the second screw 93. Before installing the first screw 92, the height of the second screw 93 must be adjusted to leave installation space for the first screw 92, which is very inconvenient. Therefore, we propose a new type of motor with a convenient carbon brush sleeve installation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of motor with convenient carbon brush sleeve installation.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A novel motor with convenient carbon brush sleeve installation, comprising a stator, an output shaft, and a commutator. A moving element is disposed inside the stator, one end of which is connected to the output shaft, and the other end of which is connected to the commutator. A first bracket and a second bracket are respectively mounted on the upper and lower sides of the stator. The bearing of the output shaft is disposed on the first bracket, and the commutator is rotatably mounted on the second bracket. Carbon brush sleeves are installed on the left and right sides of the second bracket. It also includes a locking component. The carbon brush sleeve has a limiting cylinder hole. The locking component passes through the first bracket, the stator, and the second bracket. The locking component is threadedly connected to the second bracket. The tail end of the locking component is inserted into the limiting cylinder hole of the carbon brush sleeve, thereby fixing the carbon brush sleeve to the second bracket.

[0005] To further elaborate, the carbon brush sleeve has a locking flap at the limiting cylinder hole, and the number of locking flaps is at least two.

[0006] To further elaborate, the groove depth between two adjacent snap-fit ​​segments is h1, and the height of the limiting cylinder hole of the carbon brush sleeve is h2, where h1 ≥ h2 / 2.

[0007] To elaborate further, the second bracket has insertion ports on both the left and right sides, the carbon brush sleeve is inserted into the insertion ports of the second bracket, and the commutator is located between the two insertion ports.

[0008] To further elaborate, the tail end of the locking member is provided with a thread, the tail end is located at one end of the locking member, and the other end of the locking member is provided with a limiting head.

[0009] To elaborate further, the locking component is a screw.

[0010] The beneficial effects of this utility model are as follows: The carbon brush sleeve of this utility model adopts a structure design of limiting cylinder hole. After the carbon brush sleeve is inserted into the insertion port of the second bracket, the carbon brush sleeve is limited by the locking part. The tail end of the locking part protrudes from below the threaded connection hole of the second bracket and is inserted into the limiting cylinder hole of the carbon brush sleeve, so that the carbon brush sleeve can be fixed at the second bracket. The operation is simple, convenient and quick. Attached Figure Description

[0021] Combined with appendix Figure 1 and attached Figure 2 As shown, the bearing 21 of the output shaft 20 is mounted on the first bracket 50, the commutator 30 is rotatably mounted on the second bracket 60, and carbon brush sleeves 70 are installed on the left and right sides of the second bracket 60. The carbon brushes are specifically mounted on the carbon brush sleeves 70. The carbon brush sleeves 70 are provided with limiting cylinder holes 71. The locking member 80 passes through the first bracket 50, the stator 10, and the second bracket 60. The locking member 80 is threadedly connected to the second bracket 60. The tail end of the locking member 80 is inserted into the limiting cylinder hole 71 of the carbon brush sleeve 70, thereby fixing the carbon brush sleeve 70 at the second bracket 60.

[0022] Combined with appendix Figure 3 and attached Figure 6 As shown, the carbon brush sleeve 70 has a locking flap 72 at the limiting cylinder hole 71, and the number of locking flaps 72 is at least two. The groove depth between two adjacent locking flaps 72 is h1, and the height of the limiting cylinder hole 71 of the carbon brush sleeve 70 is h2, where h1 ≥ h2 / 2.

[0023] The second bracket 60 has insertion ports 61 on both the left and right sides. The carbon brush sleeve 70 is inserted into the insertion ports 61 of the second bracket 60, and the commutator 30 is located between the two insertion ports 61.

[0024] The tail end 82 of the locking member 80 is threaded and is located at one end of the locking member 80. The other end of the locking member 80 is provided with a limiting head 81. The locking member 80 may specifically be a screw.

[0025] When assembling the motor, first install the first bracket 50 above the stator component 10, then as shown in the attached diagram.
