Abstract

The invention relates to the technical field of gear precision. The invention discloses a gear clearance measuring device. The gear clearance measuring device is used for measuring the gear clearanceof a gear pair at least comprising a first gear and a second gear which are meshed with each other. The gear clearance measuring device comprises a main body part and a holding part;the main body part(10) is used for being fixedly arranged on thefirst gear; a reading meter (11) is arranged on the main body part (10); the holding part (21) is installed on the main body part (10) through an elasticpiece (22);a connecting piece used for driving a second gear meshed with a first gear to rotate when the holding piece(21) swings is arranged on the holding piece(21), and a contact of the reading meter (11) makes contact with the holding piece(21). The measuring device provided by the invention is convenient to use, and can greatly improve the efficiency of gear clearance measurement.

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...
