Bulk conveyor adopting variable-thickness planetary gearbox

Abstract

The invention relates to the field of bulk conveying, in particular to a bulk conveyor adopting a variable-thickness planetary gearbox. The bulk conveyor comprises a conveyor belt, a plurality of drive rollers, the variable-thickness planetary gearbox and a drive motor, wherein the conveyor belt is wound and distributed on the drive rollers; one end of each drive roller is equipped with a rotary drive device; the drive rollers are connected with the variable-thickness planetary gearbox through the rotary drive devices; the input end of the variable-thickness planetary gearbox is connected witha drive motor; the variable-thickness planetary gearbox comprises a first-stage transmission chain, a planet carrier, a planetary pin, double variable-thickness planetary gears, a first variable-thickness gear ring, a second variable-thickness gear ring, a housing assembly and an output shaft, wherein the first variable-thickness gear ring is connected with the output shaft as an output end; andthe output shaft is connected with the rotary drive devices on the drive rollers. The bulk conveyor adopts a non-solar-wheel drive mode, guarantees a small gap and a small return difference of outputand optimizes the structure; and conveying speed of the conveyor is more stable.

Description

[technical field] [0001] The invention relates to the field of bulk material conveying, in particular to a bulk material conveyor adopting a thickened planetary gearbox. [Background technique] [0002] In the prior art, a common reducer is usually installed outside the motor to control the speed of the conveyor belt through a deceleration control device. The deceleration control device is generally driven by a sun gear, and the existing reducer mainly includes a cycloidal gear box. Ordinary planetary gearboxes, worm gearboxes and harmonic gearboxes, ordinary single-stage and double-stage planetary gearboxes have a small range of reduction ratios, and worm gearboxes have a large reduction ratio, but the application range is limited due to low input speeds. The most important thing is that the cycloidal pinwheel gearbox is driven by the crankshaft, with high transmission precision, complex mechanism, and extremely high processing technology requirements; the harmonic gearbox i...

[0002] In the prior art, a common reducer is usually installed outside the motor to control the speed of the conveyor belt through a deceleration control device. The deceleration control device is generally driven by a sun gear, and the existing reducer mainly includes a cycloidal gear box. Ordinary planetary gearboxes, worm gearboxes and harmonic gearboxes, ordinary single-stage and double-stage planetary gearboxes have a small range of reduction ratios, and worm gearboxes have a large reduction ratio, but the application range is limited due to low input speeds. The most important thing is that the cycloidal pinwheel gearbox is driven by the crankshaft, with high transmission precision, complex mechanism, and extremely high processing technology requirements; the harmonic gearbox is a surface contact multi-teeth meshing, with a compact structure but the output is an elastic piece cup ring , the meshing position and the output part must be elastically deformed, and the impact resistance of the structure is intersected. Therefore, with the development and application of new technologies, the requirements for gearboxes and joints continue to increase
