A simple adjustment device for eccentric wheel mass-diameter product based on the principle of static balance

Abstract

The invention relates to a simple adjustment device for eccentric gear mass-radius product based on a principle of static balance and relates to the field of design of mass-radius product adjustment devices. The device comprises a calibration component, an expansion sleeve, a central shaft, an eccentric gear assembly, support frames, a base and an adjustable support, wherein the base is a horizontally-placed rectangular plate-like structure; the adjustable support is fixedly mounted on the lower surface of the base to achieve horizontal leveling of the base; the support frames is vertically fixedly mounted on the upper surface of the base; the central shaft is horizontally mounted between the support frames; the expansion sleeve is a hollow sleeve structure; the expansion sleeve is sleevedon the outer wall of the central shaft; the calibration component is vertically fixedly mounted vertically below the axial end of the expansion sleeve; the eccentric gear assembly is sleeved on the outer wall of the central shaft; and the eccentric gear assembly is abutted against the other axial end of the expansion sleeve. The device of the invention is simple, the construction cost is low, thereplacement is easy, and adjustment of the mass-radius product of various types of eccentric gears is realized.

Description

technical field

[0001] The invention relates to the design field of a mass-diameter product adjustment device, in particular to a simple adjustment device for the mass-diameter product of an eccentric wheel based on the principle of static balance. Background technique

[0002] The key components of centrifuges, centrifugal actuators and other equipment are eccentric wheels or eccentric blocks. The rotation of eccentric wheels will generate centrifugal output force, and its mass-diameter product accuracy is directly related to the output force accuracy. How to adjust the mass-diameter product of the eccentric wheel is a common problem.

[0003] The general-purpose mass-diameter product measurement and adjustment equipment has two disadvantages: one is that the cost is relatively high, and the other is that each type of eccentric wheel needs an independent fixed tooling for adjustment. For occasions with multiple eccentric wheel types and low precision requirements, general ...
