Soft-start reducer

Abstract

The invention relates to a soft-start reducer. A bevel gear input mechanism in a box body is connected with a planetary gear transmission mechanism connected with the output of the output shaft. A braking mechanism comprises a viscous liquid brake, an acceleration bevel gear shaft, an acceleration bevel gear, an acceleration gear shaft and an acceleration gear, wherein the input of the viscous liquid brake is connected with one end of the acceleration gear shaft; the acceleration gear shaft is supported in the box body; the acceleration bevel gear is sleeved on the acceleration gear shaft; the acceleration bevel gear is meshed with other end of the acceleration bevel gear shaft; and the acceleration gear shaft is provided with an acceleration gear meshed with the outer ring of the internal and external gear rings of the planetary gear transmission mechanism. The external viscous liquid brake brakes the internal and external gear rings of the planetary gear transmission mechanism through a bevel gear acceleration braking mechanism and a bevel gear reduction input mechanism stabilizes the input power, so the soft start of the reducer under the loaded condition of heavy equipment is realized. The reducer has a compact structure, small installation space, wide speed ratio range, stable transmission performance, high efficiency and long service life and is favorable for model selection of users.

Description

technical field [0001] The present invention relates to a soft start reducer, specifically a liquid viscosity controlled soft start reducer, suitable for belt conveyors, scraper conveyors, various ball mills, mining machinery, papermaking machinery, metallurgical machinery and other heavy Soft start, stop and multi-drive power balancing of load equipment. Background technique [0002] Soft start technology refers to a technology in which mechanical equipment can gradually overcome the inertia of the entire system and start slowly and smoothly at the speed required by the design under full load or heavy load conditions. For mechanical equipment with large inertial loads, the soft start of the equipment can not only effectively reduce the impact of the motor on the transmission system and the actuator during startup, but also prolong the service life of the reducer and other important mechanical equipment connected to it. It can also greatly shorten the impact time of the sta...
