Speed reducer with load detection function

Abstract

The invention provides a speed reducer with a load detection function and relates to the technical field of improvement on mechanical equipment. A pair of oil seals, a set of wave washers and a bearing are sequentially mounted between a motor shaft ad a gearbox A; a switch mounting plate is fixedly mounted on the outer side of a motor rear support; a switch contact disc is matched with the switch mounting plate; the other end of the motor shaft penetrates through the motor rear support to be fixedly connected with center holes of a plain washer and the switch contact disc through screws; the bearing and one set of wave washers are arranged between the motor shaft and the motor rear support; two contact switches are mounted the switch mounting plate and respectively positioned on the left side and the right side of the switch contact disc; and an A end, a B end and a COM end of each contact switch are led out through conducting wires. The speed reducer is scientific and reasonable in design, the load of the speed reducer can be detected easily, the situation that a motor emits heat and then load is detected is avoided, and the problem of over-heating about the motor due to a high load of the speed reducer is solved.

Description

Technical field: [0001] The invention relates to the technical field of mechanical equipment improvement, in particular to a speed reducer with an overload detection function. Background technique: [0002] The reducer is a relatively precise machine, the purpose of using it is to reduce the speed and increase the torque. The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. [0003] The reducer is prone to many failures during work, and the causes of each failure are more complicated and need to be...
