A measuring technology of gear gap between water pump gear and crankshaft gear

Abstract

The invention discloses a measuring technology of a gear clearance between a water pump gear and a crankshaft gear. The measuring technology includes the following steps that: the water pump gear is assembled on the rotation shaft of a water pump, a water pump turbine is installed on the rotation shaft through a fastening nut on the water pump turbine, and the water pump is assembled to an engine, and the water pump gear and the crankshaft gear are engaged with each other; the crankshaft of the crankshaft gear is fixedly installed; a first sealing flange at the inlet of the water pump is disassembled, a measurement fixture is concentrically connected onto the fastening nut, the measurement fixture is provided with two scribed lines, and the distance between the two scribed lines is the reference circle diameter of the water pump gear; a second sealing flange at the outlet of the water pump is provided with a supporting mechanism provided with a dial indicator, and the pushing pin of the dial indicator abuts against one of the scribed lines; the dial indicator is zeroed; and the water pump gear is rotated towards the direction of the dial indicator. The measuring technology is simple in measuring process and easy in operation, and can assist in shortening measuring time and improving working efficiency. The measurement of the gear clearance between the water pump gear and the crankshaft gear can be realized through the dial indicator, and measuring accuracy is high.

Description

technical field [0001] The invention relates to a process for measuring the gear gap between a water pump gear and a crankshaft gear. Background technique [0002] In the manufacturing process of the engine, the measurement and adjustment of the gear gap is essential. The gear gap is: when the gears are meshed and driven, in order to form a lubricating oil film between the meshing tooth profiles, to avoid thermal expansion caused by the friction of the teeth And stuck, the gap left between the tooth profiles is called gear gap; and, during meshing transmission, the meshing position of adjacent two teeth is the pitch circle place, which is also well known to those skilled in the art. [0003] The traditional gear clearance measurement methods are as follows: [0004] 1. Hand feeling method: Experienced operators use their hands to shake the gears based on their experience. The specific steps are: [0005] a. Fix a gear through tooling; [0006] b. Shake the other gear by h...
