Description
Technical field
The utility model belongs to field of mechanical technique, specifically relates to a kind of speed reducer.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtain the mechanism of larger torque.The effect of speed reducer mainly contains: 1, reduction of speed improves output torque simultaneously, and the moment of torsion export ratio is taken advantage of reduction speed ratio by motor output, but will note exceeding the speed reducer rated torque; 2, slow down and to have reduced simultaneously the inertia of load, inertia be reduced to reduction speed ratio square.
be used at present the mechanism of transferring power and motion, the application area of speed reducer is quite extensive, almost can see its trace in the transmission system of various machinery, boats and ships from the traffic tool, automobile, locomotive, heavy machinery for building, the machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch etc., it uses the transmission work from large power, to little load, accurate angle transmission can be seen the application of speed reducer, and on commercial Application, speed reducer has deceleration and increases torque functions, therefore be widely used in the conversion equipment of speed and moment of torsion.
Existing speed reducer, when in use, transmission not steadily, noise is large, working life is shorter, can not well adapt to long-term work under rugged environment.
