Problems solved by technology

The three coordinates are generally placed in a special precision measurement room, and the detection cost is relatively high
Compared with the three-coordinate method, the symmetry can be quickly detected and the detection cost can be reduced, but its disadvantages are: 1) It cannot detect the symmetry of the gear keyway relative to the gear tooth thickness; 2) Two dial gauges are required for measurement, Complex structure; 3) cumbersome operation during mass detection

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: the gear keyway symmetry inspection tool of this embodiment includes a mandrel 1 , a measuring column 2 and a dial indicator 3 . The mandrel 1 is a vertical stepped shaft, which includes a bottom shaft section 101, a flange 102, a transition shaft section 103 and an upper shaft section 104 from bottom to top, wherein the bottom shaft section 101 is inserted into the positioning hole 901 on the base 9, and The lower end surface of the flange 102 is lapped on the top surface of the base 9, the outer diameter of the upper shaft section 104 is equal to the diameter of the inner hole of the gear 100, and the gear 100 is inserted into the core from top to bottom along the upper shaft section 104 through its central hole. shaft 1, and the upper end face of the transition shaft section 103 supports the lower end face of the gear 100. In order to measure...

Abstract

The invention discloses a tool for testing the degree of symmetry of a gear key groove, and the tool comprises a central spindle, a measuring column, and a dial indicator. The central spindle is located in a central hole of a gear in a sleeved manner. The periphery of the central spindle is provided with a positioning key which is corresponding to the key groove on the central hole of the gear. One end, close to the gear, of the measuring column is provided with a tooth groove matched with the shape of the gear. The axis of the measuring column, the central line of the tooth groove and the central line of the positioning key are collinear with the center of the central spindle. The measuring column can swing around one end far from the gear. The central spindle can measure the swinging of the measuring column after being equipped with gears with different errors, and the dial indicator is used for measuring the swinging amount so as to calculate the degree of symmetry of the gear key groove. The tool can detect the degree of symmetry of the gear key groove relative to the tooth thickness, is convenient to operate, does not need three-dimensional operation, and is suitable for batch detection.

Description

technical field [0001] The invention relates to a check tool, in particular to a gear keyway symmetry check tool. Background technique [0002] At present, there are two main methods for detecting the symmetry of the gear keyway: 1) Positioning block method: Use a height gauge to level the side of the keyway on the platform, and then measure the distance from the two sides of the keyway and the center hole of the gear to the platform with the height gauge, according to three The measured distance is used to calculate the symmetry of the keyway. Due to the low detection efficiency, this method is mainly suitable for small batches or trial production. 2) Measure with three coordinates. The three coordinates are generally placed in a special precision measurement room, and the detection cost is relatively high. [0003] For this reason, CN203163669U discloses a kind of gear keyway symmetry checker, comprises checker base plate, the hollow positioning mandrel that is arranged ...
