Abstract
Description
Technical Field
[0001] The utility model relates to a roller reduction motor module based on a cycloid reducer and used in a heavy-duty electric roller. Background Art
[0002] The planetary reducers currently used in the field of heavy-duty electric rollers have a much lower gear modulus than the gear modulus in three-phase asynchronous reduction motors due to limited space and volume, which results in a lower impact resistance of the planetary reducer and a lifespan that cannot reach the same level as that of three-phase asynchronous reduction motors. However, electric rollers have many advantages in conveying products, such as a small number of parts, compact structure, and easy installation. It is necessary to develop roller reduction motor modules with higher rigidity and service life for heavy-duty chain conveying applications. Utility Model Content
