The excessive or insufficient clearance of the rolling bearings in the deceleration motor is harmful.
In practical use, the working clearance of rolling bearings will affect the load distribution, vibration, noise, friction torque, and lifespan within the rolling bearings. The working clearance of rolling bearings is not suitable and can cause serious harm to the reduction motor, mainly as follows.

Working clearance isReduction motorAn important quality standard for rolling bearings, and also an important parameter in the use of rolling bearings. In practical use, the working clearance of rolling bearings will affect the load distribution, vibration, noise, friction torque, and lifespan of the rolling bearings. An inappropriate working clearance of rolling bearings can cause serious harm to reduction motors, mainly as follows.
(1) The working clearance of the rolling bearings in the reduction motor is too small.
If the working clearance of the rolling bearings is too small, it will increase the friction torque of the rolling bearings, thereby generating a large amount of heat, which can easily cause thermal damage to the rolling bearings.
This is because when the working clearance of the rolling bearings is too small, it will lead to poor lubrication between the rolling elements and the inner and outer rings of the rolling bearings, generating a large amount of heat due to dry friction, resulting in wear, bonding, and cracking of the inner and outer rings of the rolling bearings, which can cause damage to the rolling bearings.
(2) The working clearance of the rolling bearings in the reduction motor is too large.
The working clearance of the rolling bearings is too large, mainly due to the selection of a natural clearance that is too large and insufficient clamping force of the rolling bearings.
In high-speed operation of the reduction gearbox, when the natural clearance of the rolling bearings is relatively large, it will cause the working clearance to also be relatively large, which will result in greater vibration during the operation of the reduction motor, reducing the lifespan of the rolling bearings.

Introduction to Micro DC Gear Motors
Introduction to Micro DC Gear Motors Micro DC gear motors are a miniaturized motor system, typically consisting of a DC motor and a gearbox. Here are some related introductions to micro DC gear motors: DC Motor Section: Working Principle: The DC motor generates current by moving a conductive coil in a magnetic field, thus producing electromagnetic force to drive the motor's rotation. Structure: Micro DC motors usually adopt a separate structure, including an armature (rotating part) and an electromagnet (stator part). Types: Common types of DC motors include brushed DC motors and brushless DC motors. Brushed DC motors use brushes to connect to the armature, while brushless DC motors control current through an electronic speed controller, eliminating the need for brushes. Gearbox Section: Function: The gearbox is used to slow down the motor's output speed while increasing torque. This is crucial for applications requiring higher torque and lower speeds, such as robotic arms and camera gimbals. Structure: Gearboxes typically consist of gears that achieve the reduction ratio through different gear combinations. The reduction ratio is the ratio of input speed to output speed. Types: Common types of gearboxes include planetary gears, worm gears, and helical gears. Different types of gearboxes are suitable for different application scenarios. Applications: Micro DC gear motors are widely used in various fields, including consumer electronics (such as cameras and printers), medical devices, robotics, and automotive electronics. In these applications, micro DC gear motors are typically used to control precise movements, provide sufficient torque, and achieve efficient performance in limited spaces. Control and Drive: Micro DC gear motors usually require corresponding electronic speed controllers or controllers to precisely control rotation speed and direction. The control system can adjust the motor's output according to application needs, achieving precise position control and speed regulation. Performance Parameters: The performance parameters of micro DC gear motors include rated voltage, rated speed, rated torque, efficiency, etc. These parameters are crucial for selecting and designing motor systems. In summary, micro DC gear motors have been widely applied under the trends of miniaturization, precision, and efficiency, providing reliable driving force for many electric devices and systems.
