Abstract

The invention relates to the technical field of gear precision, and discloses a gear clearance measuring device, which comprises a main body part (10), an operation part (20) and a feeler lever (30),wherein the main body part can be mounted on a first gear and can keep the first gear stationary, and a reading meter (11) is arranged on the main body part; the operation part comprises a connectingpiece, a holding piece (21) and an elastic piece (22), the holding piece is installed on the main body part through the elastic piece, the connecting piece is used for being matched with the second gear to drive the second gear to rotate, and an attaching groove attached to the edge of the second gear when the main body part (10) is installed on the first gear is formed in the holding piece (21);one end of the feeler lever (30) is fixed to the holding piece (21), and the other end of the feeler lever (30) makes contact with a contact of the reading meter (11). According to the gear clearancemeasuring device provided by the invention, the measuring efficiency of the gear clearance can be improved.

Description

technical field [0001] The invention relates to the technical field of gear precision, in particular to a gear clearance measuring device. Background technique [0002] Existing methods for measuring gear clearance include metering. In this method, one gear needs to be fixed, a clamping rod is installed on the other gear, and then the swing angle a of the gear equipped with the clamping rod is measured. The reading difference j between the two limit positions is measured on the measuring instrument, R is the radius of the unfixed gear, L is the plane distance between the contact of the measuring tool and the rotation axis of the unfixed gear, according to the arc The length calculation formula, the reading difference j is the arc length corresponding to the central angle with the angle a as the degree in the circle whose radius is L and the center of the circle is the center of the second gear, and the gear gap jn is the central angle with the angle a as the degree. The arc...
