Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to the heat dissipation tooth rear cover of a servo motor housing. Background Technology

[0002] Servo motors, capable of precisely controlling speed and position, are widely used in automatic control systems. The back cover is a key component constituting the servo motor's housing, and its performance plays a crucial role in the overall operational stability of the servo motor. However, existing servo motor back covers have the following drawbacks: 1. Existing servo motor back covers lack a heat dissipation structure, resulting in poor heat dissipation and hindering the effective dissipation of heat from inside the motor; 2. The servo motor back cover houses bearings. During motor operation, the bearings bear the frictional force generated by the load, leading to frictional heat and increased temperature. Due to the lack of an effective heat dissipation design, heat accumulates continuously, causing the bearing temperature to rise further. High temperatures not only cause thermal expansion, increasing frictional resistance, but also lead to lubricant deterioration and failure, resulting in accelerated bearing wear and a reduced service life.
