Abstract

The invention relates to a heavy-load soft-start speed reducer. A bevel gear input mechanism in a box body is connected with a planetary transmission mechanism with a braking mechanism, the planetarytransmission mechanism is connected with output of an output shaft, the braking mechanism comprises a hydro-viscous brake, a speed increasing bevel gear shaft, a speed increasing bevel gear, a speed increasing gear shaft and a speed increasing gear, input of the hydro-viscous brake is connected with one end of the speed increasing gear shaft, the speed increasing gear shaft is supported in the boxbody, the speed increasing bevel gear is arranged on the speed increasing gear shaft in a sleeving mode, the speed increasing bevel gear is engaged with the other end of the speed increasing bevel gear shaft, and the speed increasing gear shaft is provided with the speed increasing gear engaged with the outer ring of an inner and outer gear ring of the planetary transmission mechanism. The external hydro-viscous brake is adopted to brake the inner and outer gear ring of the planetary transmission mechanism through a bevel gear speed increasing brake mechanism, a bevel gear speed reducing input mechanism is matched to stably input power, the soft start of the speed reducer under the load of heavy-load equipment is realized, the structure is compact, the installation space is small, the speed ratio range is wide, the transmission is stable, the efficiency is high, the service life is long, and the selection of a user is convenient.

Description

technical field [0001] The invention relates to a heavy-duty soft-start reducer, specifically a heavy-duty soft-start reducer controlled by liquid viscosity, which is suitable for belt conveyors, scraper conveyors, various ball mills, mining machinery, papermaking machinery, metallurgical Soft starting, stopping and multi-drive power balancing of machinery and other heavy-duty 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 s...
