Abstract

The invention discloses a speed detector for a large diameter rotating shaft without a protruding end. The speed detector comprises a rotational speed extractor, a movable bracket, a buffer device, afixed bracket and a rotary encoder, wherein the rotational speed extractor mainly comprises a pair of gear mechanisms; the rotational speed is extracted by gear mesh; the rotary encoder is arranged onan output shaft; one end of the rotational speed extractor is arranged on a to-be-detected rotating shaft and the other end of the to-be-detected rotating shaft is arranged on the movable bracket; the fixed bracket is arranged on a hydraulic motor base; and the buffer device is arranged between the movable bracket and the fixed bracket. According to the speed detector for the large diameter rotating shaft without the protruding end, disclosed by the invention, the rotational speed measurement can be carried out without disassembling or reforming the rotating shaft; and the speed detector hasthe advantages of accurate speed measurement, convenience in installation and low transformation cost.

Description

technical field [0001] The invention relates to a speed measuring device for a rotating shaft, in particular to a speed measuring device for a large-diameter rotating shaft without a projecting end. Background technique [0002] Large-diameter rotating shafts without extended ends are widely found in large rotating equipment, such as the rotating shaft of hydraulic elevator drums, one end is connected to the hydraulic motor, and the other end is connected to the drum. Install a speed measuring device at the end. [0003] In order to monitor the rotational speed of a large-diameter rotating shaft without a protruding end, it is necessary to disassemble and assemble this type of rotating shaft and make a large structural modification, which is time-consuming and costly. SUMMARY OF THE INVENTION [0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a speed measuring device for a large-diameter rotating shaft without a...
