Gear clearance bevel measuring device and method

Abstract

The invention discloses a gear clearance bevel measuring device which comprises a measuring rod and further comprises a measuring seat with a hollow structure.The measuring rod can be axially and movably inserted into the measuring seat, a measuring piece which can be inserted into a gear clearance is arranged at one end of the measuring rod, and the other end of the measuring rod is connected with a measuring head of a dial indicator.A positioning spring capable of limiting the positional relation between the measuring piece and a gear to be measured is arranged between the end, close to the measuring piece, of the measuring rod and the measuring seat.The invention further discloses a gear clearance bevel measuring method.The gear clearance bevel measuring device is simple in structure, convenient to operate, high in measurement accuracy and good in practicability and utilizes the slope of the measuring piece and the depth of the measuring piece embedded into the gear clearance to directly calculate an inter-tooth clearance value of the gear.

Description

technical field [0001] The invention relates to the field of manufacturing and assembling of mechanical equipment, more specifically, it relates to a device and method for measuring gear clearance slopes. Background technique [0002] In the process of mechanical equipment manufacturing and assembly, the assembly clearance of gears affects the assembly quality and transmission efficiency of equipment. Therefore, there are certain technological requirements for the gap between the teeth of the two gears, and the gap needs to be controlled within a certain range of technological requirements. At present, the commonly used methods for measuring gear clearance are feeler gauge measurement and angle conversion measurement. The feeler gauge measurement method is to combine feeler gauges of different thickness specifications into feeler gauges of different thicknesses, and then insert the combined feeler gauge into the gear. In the gap, during the measurement process, if you feel ...

Problems solved by technology

[0003] In the current method of measuring gear clearance with a feeler gauge, since the thickness of each piece of feeler gauge is manufactured in advance, the accuracy of the measured value can only reach the fixed thickness of the thinnest measuring piece, which can only be roughly estimated by measuring the gear clearance. Gap size, the exact value of the gear gap cannot be accurately measured, the measurement error is large, and the operator needs to judge the gap width to be measured based on past experience, so that different feeler gauge pieces can be combined into a gear gap width roughly equivalent to the measured gear gap. Combining the feeler gauge and then measuring, the operation is cumbersome, and the thinner measuring piece is easy to wear and deform during the measurement process, resulting in damage to the measuring piece, which increases the cost of use. If the measured data needs to be recorded, it needs to be recorded manually Save the records in the way to increase the intensity of manual operation

For the method of angle conversion measurement, when the measurement reference plane and the radius of the gear to be measured change, it needs to be converted into a correspondingly different measurement calculation program. Before measurement, one of the measured gears needs to be fixed and the measurement reference plane should be selected, and the measuring rod Fixed on another gear to be measured, it can only measure the gear gap of a fixed size, and the scope of application is small
