Abstract
The utility model discloses a motor with hydraulic torque conversion which belongs to the control technical field of a motor torque, the purpose of the motor with hydraulic torque conversion is to provide a buffering with the advantages of easy starting, impact buffering, energy saving, low failure rate and long service life. A supporting seat is arranged on the lower side of the motor, a shaft coupling is arranged on the power output shaft of the motor, and a hydrodynamic torque converter is integrated with the motor through the shaft coupling. The hydrodynamic torque converter mainly comprises an outer shell, a pump wheel which is arranged in the outer shell, a turbine wheel which is arranged in the outer shell, a guide wheel fixed on the outer shell, a driving shaft fixed with the pump wheel, and a driven shaft fixed with the turbine wheel.
Description
The utility model belongs to the control technique field of motor torque.
Common motor is when work; directly or by speed reducer drive the heavy load starting of big inertia; starting difficulty; starting current is big; make electric motor overheating; burn out when serious, often adopt motor overload protection at present or make large capacity motor drive little load working machine, caused loss and the use inconvenience on the electric power.
The purpose of this utility model provides a kind of easy starting, can slow down the motor that impact, saving power, fault are few, the life-span is long.
The utility model comprises motor, be arranged on the bearing of motor below, be installed in the coupling on the motor power output shaft, the fluid torque converter that is connected as a single entity by coupling and motor, fluid torque converter mainly comprises shell, and in the enclosure pump impeller and turbine are installed, and is fixed on the guide wheel on the shell, with the fixing driving shaft of pump impeller, with the fixing driven shaft of turbine.
During the utility model work, the pump impeller rotation by the motoring fluid torque converter drives the turbine rotation through hydraudynamic drive, and the driven shaft on the turbine directly or through speed reducer drives working machine.The utlity model has following characteristics:
1, starting torque is little, so starting current is little, and the starting time is short, can prolong the working life of motor.
2, can automatically change moment of torsion with the variation of external load, therefore can slow down impact.
3, the increase with load automatically increases moment of torsion and reduces rotating speed, therefore can reduce motor capacity, improves the power of electric motor factor, saving power.
Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.
Accompanying drawing has provided embodiment of the present utility model, and accompanying drawing is a structural representation of the present utility model.
In the present embodiment, motor (1) is selected J2-81-4 type threephase asynchronous for use, the bearing (8) that is arranged on motor (1) below is cylinder iron made, the coupling (10) that is installed on the motor power output shaft (9) is selected the YL11 flange coupling for use, select the YB355-2 type for use by the fluid torque converter (2) that coupling (10) and motor (1) are connected as a single entity, the shell (11) of fluid torque converter (2), pump impeller (5), turbine (4), guide wheel (3) are cylinder iron made, and driving shaft (7) and driven shaft (6) are made of round steel.
Working principle of the present utility model is: motor (1) drives pump impeller (5) rotation through coupling (10), flow of fluid in fluid torque converter (2) shell (11), guide wheel (3) the rear driving turbine (4) of flowing through rotation, driven shaft (7) rotates thereupon, produce moment of torsion, directly or by speed reducer drive working machine work.
Claims (1)
1, a kind of hydraulic moment changeable motor, it comprises motor (1), be arranged on the bearing (8) of motor (1) below, it is characterized in that: also comprise the coupling (10) that is installed on the motor power output shaft (9), the fluid torque converter (2) that is connected as a single entity by coupling (10) and motor (1), fluid torque converter (2) comprises shell (11), be installed in the pump impeller (4) and the turbine (5) of shell (11), be fixed on the guide wheel (3) on the shell (11), with the fixing driving shaft (7) of pump impeller (5), with the fixing driven shaft (6) of turbine (4).
