Testing tool for measuring tooth thickness of heavy-duty spiral bevel gear on line

Abstract

The invention discloses a testing tool for measuring the tooth thickness of a heavy-duty spiral bevel gear on line, which comprises a ball head, an indicator clamp, a dial indicator, a movable clamp,a vertical rod, a slide rod, and a base. Both the vertical rod and the slide rod are cylindrical straight rods, and the vertical rod is articulated with the slide rod through the movable clamp on oneside. The movable clamp, which is a tightness-adjustable clamp, is used for changing the locking position and bending angle of the clamped slide rod. The extended end of the slide rod is directly articulated with the indicator clamp, and the dial indicator, the meter of which is downward, is inserted in the horizontal indicator clamp. The meter of the dial indicator can be freely extended and retracted, and the ball head is stuck at the end of the meter. The bottom end of the vertical rod is fixedly connected to the angled base. The testing tool is a rod type testing tool, the structure is simple and light, moreover, the requirement on detection conditions is not high, above all, a workpiece does not need to be moved during measurement, and therefore the testing tool is suitable for on-line detection on the production site. Because only one person is needed to use the testing tool for detection, the testing tool can save manpower in comparison with the prior art, and thereby the production cost can be remarkably reduced.

Description

technical field [0001] The invention relates to a measuring tool for measuring the length dimension, in particular, the invention relates to a measuring tool for measuring the tooth thickness of a gear, in particular to an online measuring tool for measuring the tooth thickness of a heavy-duty spiral bevel gear. Background technique [0002] The heavy-duty spiral bevel gear is the core component in the transmission chain of engineering vehicles. Since this part directly bears torque, its structure must have sufficient strength and rigidity to meet the supporting requirements. Therefore, the spiral bevel gears for engineering vehicles are relatively large in size, usually with a diameter of more than 450mm and a single piece with a net weight of more than 80kg. The tooth shape of the spiral bevel gear is more complicated than that of the common straight tooth. The measurement of this three-dimensional tooth shape is difficult, and it is usually sent to the inspection room for...

Problems solved by technology

However, at least two people are required to cooperate with this set of inspection tools, otherwise it cannot be used for inspection

It is necessary to improve the design of the existing technology to increase the production cost by employing more workers in the inspection positions.
