Abstract

The invention relates to a speed measuring device, in particular to a dustproof and waterproof speed measuring device. The technical solution of the present invention is: a dustproof and waterproof speed measuring device, including a base, a rotary encoder, a fixed piece, a bolt, a rotating shaft, a bearing, a bearing seat, a shaft coupling, an O-shaped sealing ring, a shield, a fixed sleeve, a press Cover, sealing felt ring and screws, fixed plate, base, fixed sleeve and bearing seat are connected together by bolts, a groove is set between the base and the fixed sleeve, O-ring is installed in the groove; the gland has a round hole , the round hole is set on the rotating shaft, the screw fixes the gland on the bearing seat and presses the bearing tightly; the round hole of the gland is provided with a trapezoidal groove, and the sealing felt ring is installed in the trapezoidal groove to realize the sealing between the gland and the rotating shaft seal. The velocity measuring device of the invention can work normally under various conditions of use, especially in environments with serious dust pollution or humidity.

Description

technical field [0001] The invention relates to a speed measuring device, in particular to a dustproof and waterproof speed measuring device. Background technique [0002] At present, the application range of speedometers is getting wider and wider, so it is required that the speedometers can work normally under various conditions of use. In the existing speedometer, in the environment with severe dust pollution or humidity, due to the poor sealing, dust or moisture will occur, causing internal parts to malfunction, especially the rotary encoder is affected, and the test data is inaccurate. Contents of the invention [0003] The invention provides a dustproof and waterproof speed measuring device, which can work normally under various conditions of use, especially in environments with severe dust pollution or humidity. [0004] Technical scheme of the present invention is as follows: [0005] A dustproof and waterproof speed measuring device, including a base, a rotary e...
