Description

Technical Field

[0001] This utility model relates to an electric roller based on a cycloidal reducer for use in the field of conveying equipment. Background Technology

[0002] Currently, electric rollers are used as the driving element in logistics conveying systems. Compared to traditional geared motors, they have a smaller structural size and a smaller internal planetary reducer, resulting in a gear module that is about twice as small as that of traditional geared motors. This leads to a shorter service life for electric rollers compared to traditional geared motors. To increase the gear module of the reducer inside the electric roller, the number of parts can be reduced, manufacturing costs can be lowered, and the service life of the electric roller can be increased. Therefore, it is necessary to develop an electric roller based on a cycloidal reducer. Utility Model Content

[0003] Based on the above and the shortcomings of the existing structure, this utility model provides an electric roller based on a cycloidal reducer, which can increase the gear module of the reducer and extend the service life of the electric roller.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An electric roller based on a cycloidal reducer is characterized by comprising a driven end (1), a steel pipe (2), a cycloidal reducer (3), a motor (4), an encoder (5), and a roller drive output module (6); wherein the cycloidal reducer (3), the motor (4), the encoder (5), and the roller drive output module (6) constitute the drive end module; wherein the reducer in the roller that reduces speed and increases torque is the cycloidal reducer (3), which increases the gear module by 1.5 to 2.0 times compared to a planetary reducer of the same size; wherein the driven end (1) and the drive end module are respectively installed at both ends of the steel pipe (2) by driven end mounting screws (15) and drive end mounting screws (66) to form a whole roller; wherein the driven end (1) and the drive end module are independent modules, which are convenient to install, and can be connected to the steel pipe (2) by screws, riveting, or welding; wherein the steel pipe (2) can be made of galvanized carbon steel or stainless steel.

[0006] In the drive module, the front end of the motor (4) is connected to the cycloidal reducer (3), the output pin bearing seat (33) and the motor stator housing (41) are connected and supported by the mechanical shoulder bolt (32), the output shaft of the motor (4) is connected to the eccentric shaft (39) of the reducer, and the internal gear ring (36) of the reducer is driven to rotate by the oscillating meshing of the gear inside the cycloidal reducer (3), and the internal gear ring (36) of the reducer is connected to the steel pipe (2) by the reducer mounting screw (31) to realize the conversion and output of motor torque; the rear end of the motor (4) is connected to the roller drive output module (6) by six screws to fix the motor (4);

[0007] The cycloidal reducer (3) consists of four machine shoulder bolts (32), output pin bearing housing (33), six cylindrical pins (34), two reducer output bearings (35), reducer output internal gear ring (36), two reducer eccentric shaft bearings (37), two cycloidal gears (38), reducer eccentric shaft (39), and motor stator housing (41). The rotation of the reducer eccentric shaft (39) drives the two cycloidal gears (38) to swing up and down. Through the meshing of the cycloidal gears, the reducer output internal gear ring (36) is driven to rotate, thereby realizing the conversion and output of speed and torque.

[0008] The motor (4) consists of a motor stator housing (41), a motor stator winding (42), a rotor magnet module (43), a motor rear end cover (44), and an encoder magnet (45); the motor rear end cover (44) is equipped with an encoder circuit board (51) by encoder mounting screws (52), forming an integral encoder (5) with the encoder magnet (45), which outputs speed and position signals.

The roller drive rear end cover (61) and the roller electric control output shaft (62) are connected by welding. The connecting cable (70) passes through the roller electric control output shaft (62) and connects the encoder (5) and the motor (4) to the external drive. After the roller electric control output shaft (62) is equipped with the drive end input bearing (65), the drive end hole snap ring (64), and the drive end output bearing (68), it is installed as a whole at the tail end of the drive end bearing seat (63). Then, the drive end output drive end hole snap ring (64) is installed, so that all parts form an independent module.

The driven end sprocket bearing seat (14) is externally machined with one of the following forms: single sprocket, double row sprocket, and double set sprocket, so that the roller can achieve different structural forms and transmission methods.

[0011] Compared to using a cycloidal reducer to replace the planetary reducer inside the electric roller, this invention can increase the gear module of the electric roller reducer by 1.5 to 2.0 times, reduce the number of parts, lower manufacturing costs, and extend the service life of the electric roller, reaching or even exceeding the service life of an externally driven geared motor.
