Abstract

The invention discloses a device for measuring the thrust force of a propeller and magnetic transmission torque. The device comprises measuring tools and a test mechanism, wherein the measuring tools include a water groove, a flexible rope, a weight, a pendant and a dynamometer having a data recording function; the test mechanism comprises a sliding guide rail; a slide block A and a slide block B are arranged on the sliding guide rail; the slide block A is connected with the slide block B through a screw rod; a direct current motor is fixed on the slide block A; a bearing base is fixed on the slide block B; a thrust force measuring revolving shaft and a torque measuring revolving shaft are supported on the bearing base; the thrust force measuring revolving shaft and the torque measuring revolving shaft are arranged coaxially opposite to each other; a rolling bearing is arranged on the middle part of torque measuring revolving shaft. The device can be used for measuring the forward thrust force of the propeller under a laboratory condition, and can be used for measuring the magnetic torque of magnetic transmission and the oscillation curve of the magnetic transmission torque. The device has a very high reference value in the design of the propeller.

Description

technical field [0001] The invention relates to a test device for a propeller propulsion device with magnetic coupling transmission, in particular to a device for measuring propeller thrust and magnetic drive torque. Background technique [0002] Most underwater robots use propellers to achieve forward propulsion. Propeller propulsion devices have various implementation forms. Among them, the most advanced propeller transmission form is magnetic coupling transmission. Magnetic coupling transmission has the advantages of high transmission efficiency and good sealing effect. However, there is currently no experimental platform or test device for quantitative testing of magnetically coupled drive propeller propulsion devices. Contents of the invention [0003] The invention provides a propeller thrust and magnetic transmission torque measuring device to solve the technical problems existing in the known technology. [0004] The technical solution adopted by the present inven...
