Problems solved by technology

This method is simple and easy to operate, but it has certain requirements for the space for gear backlash measurement. For the gear transmission in a partially closed cavity, because the cavity is closed, the gear is assembled into the cavity afterward, and the backlash measurement must be performed after the gear assembly is completed. ; But after the gear assembly is completed, due to the small hole in the cavity, the dial indicator frame cannot be fixed, so the measurement operation cannot be performed or the measurement data is inaccurate

Abstract

The invention relates to a device for measuring meshing gear clearance in a closed cavity, which is mainly composed of an integrated retaining plate, a long arc plate and a measure square plate, the long arc plate is an arc shaped tile plate, the retaining plate is a round plate, the center of the circle is equipped with a round hole, the measure square plate is a square plate, the retaining plate is fixed on the inner side of the arc on one end of the long arc plate, the measure square plate is fixed on the outer side of the arc on the other end of the long arc plate, the side wall of the measure square plate is carved with a horizontal line. The measurement of the meshing gear clearance can be done with the device and measure method according to the invention, which has the merits of simplicity and convenience, high practicability, and high labor efficiency.

Description

technical field [0001] The invention relates to gear transmission, in particular to a measuring device and a measuring method for the internal gear gap of a diesel engine. Background technique [0002] The transmission forms of camshafts of marine diesel engines mainly include gear transmission and chain transmission. Due to the advantages of reliability and stability of gear transmission, it is often selected for various transmission designs. The meshing clearance of diesel engine gear transmission requires high precision, usually with 0.01mm as the precision unit. Taking meshing gears as an example, the gap requirement is 0.15~0.30mm, and the adjustment of the gap is more important. If the gap is too large, there will be a lot of noise during the gear transmission process, and due to the knocking between the gears, it is easy to If the meshing gap is too small, the gear transmission process will be unstable, and it will not be conducive to the cooling of the gears, reduc...
