Problems solved by technology

[0006] In order to solve the above problems existing in the existing large and medium-sized speed-adjusting transmission devices, the functions such as smooth transition of bidirectional stepless speed regulation, soft start, output overload torque limit protection and multi-drive power balance cannot be realized at the same time, and the structure is complex and the work performance is not good. The problem of high manufacturing and maintenance costs, the purpose of the present invention is to provide a simple structure that can simultaneously realize the functions of smooth transition of bidirectional stepless speed regulation, soft start, output overload torque limit protection and multi-drive power balance. Electromechanical-hydraulic hybrid soft-start stepless speed regulation transmission device with reliable performance and low manufacturing and maintenance costs

Abstract

A variable speed drive device of soft start-up in electromechanical liquid mixed type consists of device body, master motor, high speed ecicyclic frame, external gear shaft, involutes spline sleeve, etc.. It is featured as connecting its low speed output shaft with operation component of large power load-carry equipment as well as connecting hydraulic rotary functional element and its signal separately to hydraulic control system and master motor control circuit when said device is on service.

Description

technical field [0001] The invention relates to a device suitable for large and medium-sized conveyors, elevators, ball mills, excavators and other high-power heavy-duty equipment for soft start, soft brake, stepless speed regulation, overload torque limit protection and multi-drive power balance. The device, in particular, relates to an electromechanical-hydraulic hybrid soft-start stepless speed-regulating transmission device. Background technique [0002] The soft start of mechanical equipment means that even under full load conditions, the mechanical equipment can gradually overcome the inertia of the entire equipment and start slowly and smoothly according to the required speed. For the electrical system, soft start technology can reduce the starting current of the motor as much as possible and shorten the impact time of the starting current during the starting process, thereby reducing the impact on the motor and the power grid, saving electric energy, and protecting r...
