The invention discloses a tester for pitch cone runout of a spiral bevel gear. The tester comprises a dial indicator, and is characterized by also comprising a bottom plate, an upright post, a sliding arm, a lifting seat, a rotating block, a rotating block shaft, a dial indicator rack, a dial indicator clamping arm, a positioning shaft, a sliding shaft, a positioning shaft, bearings and a spring, wherein the upright post is fixed on the bottom plate; the sliding arm is connected to the lifting seat which can move up and down along the upright post through a screw; the rotating block is arranged on the sliding arm and can rotate 360 degrees by taking the sliding arm as the center of a circle; the dial indicator rack is arranged on the rotating block shaft and can rotate up and down by taking the rotating block shaft as the center of a circle; the bearings are arranged at the upper ends of the positioning shaft and the sliding shaft, and inner holes of the bearings are in interference fit with shaft necks; the positioning shaft is fixed on the bottom plate and is pressed by a nut; the sliding shaft is arranged on the bottom plate in a movable mode; and the bearings and an inner hole of the gear are tightly adhered through elastic force of the spring. The tester can check gears with different diameters, different face cones and different spiral angles; and moreover, data is accurate, and the detection is convenient.
Description
technical field [0001] The invention relates to the inspection of the pitch-cone run-out of a spiral bevel gear, in particular to an inspection instrument for the pitch-cone run-out of a spiral bevel gear. Background technique [0002] In the processing of spiral bevel gears, pitch cone runout is a very important item. Usually, the checker used by enterprises, because the components held by the dial indicator are fixed, the checker can only check gears with a certain diameter. The scope of use narrow. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a spiral bevel gear pitch cone runout tester. The tester can check gears with different diameters, different face cone angles, and different helix angles, and the data is accurate. Easy to detect. [0004] The technical scheme that realizes the object of the present invention is: [0005] The spiral bevel gear pitch cone runout inspection ins...
