Embodiment Construction

[0078] The method for measuring the plane quadratic enveloping toroidal worm will be further described below in conjunction with the accompanying drawings. Such as Figure 8 , this method can be applied to both horizontal measuring machines and vertical measuring machines, here we take the horizontal measuring machine as an example to illustrate.

[0079] The horizontal measuring machine includes a bed, a spindle unit and a measuring unit, and the spindle unit and the measuring head unit are installed on the bed. The spindle unit includes a spindle and a tailstock, the θ-axis circular grating is connected to the spindle, and the Z-axis grating is installed on the bed to measure the movement of the measuring head unit along the Z direction; the measuring head unit includes a base, a Y-direction carriage, an X-direction carriage and a measuring head unit. The Y-axis grating is installed on the base to measure the movement of the carriage in the Y direction, the X-axis grating i...

Abstract

The invention discloses a plane secondary enveloping ring surface worm measuring method and belongs to the field of the precise testing technology and the instrument and machine transmission technology. According to the method, a tooth surface equation of a worm is set up based on the gear space meshing principle, and the modeling method conforms to the machining method of the plane secondary enveloping ring surface worm; a mathematic model of an error term of the worm is set up according to the definition of the error term of the worm, coordinate conversion is performed on the mathematic model, the mathematic model is converted into coordinates of three axes of motion of a worm measuring machine, and three coordinate numerical solutions are obtained with the numerical solution method; a computer performs sampling route planning according to coordinate values, the coordinate values are input into a numerical control system to control movement of the measuring machine, a data collecting system synchronously collects grating values and measuring head data of the three axes and processes the collected data, and therefore high-precision measurement on the spiral line errors, the axial tooth shape errors, the normal tooth shape errors, the division errors and the axial tooth thickness deviation of the plane secondary enveloping ring surface worm is achieved.

Description

technical field [0001] The invention relates to a method for measuring a plane quadratic enveloping toroidal worm, which belongs to the technical fields of precision testing technology, instruments and mechanical transmission. Background technique [0002] The toroidal worm is a grinding worm based on the envelope of the grinding wheel. Compared with the cylindrical worm drive, the toroidal worm drive has the advantages of large number of meshing teeth, double-line contact of the worm gear tooth surface, strong bearing capacity, high transmission efficiency, long service life and grinding in accordance with the principle of repairing, etc., and its application is increasing. widely. [0003] With the development of science and technology, higher and higher requirements are put forward for the precision of the toroidal worm drive system, and its precise measurement has always been the bottleneck problem restricting its development. [0004] At present, the research on the d...
