Device for detecting gear gap

Abstract

The invention discloses a device for detecting a gear gap. The device comprises a pull rod, wherein an expansion sleeve, a buffering cushion, a measuring plate and a nut are arranged on the pull rod in sequence from bottom to top in a penetrating manner; one side of the measuring plate extends outwards and a dial indicator is mounted under the measuring plate; a reversed bowl-shaped fixed connection part is arranged at the lower end of the pull rod; a sleeving part matched with the fixed connection part is arranged at the lower end of the expansion sleeve; and at least two mounting grooves are formed in the circle of the periphery of the sleeving part. When the device is used, an impeller of a water pump is inserted into each mounting groove in the peripheral direction of the expansion sleeve and the position of the measuring device is adjusted, so that the middle axis of the device is overlapped with the middle axis of the water pump; the nut is screwed down and the measuring device is fixed on the impeller of the water pump; a gauge outfit of the dial indicator is in vertical contact with the measuring plate and the dial indicator is zeroed; and the pull rod is forcedly twisted and a swinging interval of the dial indicator is observed, and the reading is the gear gap of the water pump. The device has a simple structure and is convenient to use.

Description

Technical field [0001] The invention relates to a device for detecting gear gaps and belongs to the technical field of detection tools. Background technique [0002] As we all know, the cooling system is very important for internal combustion engines. It can not only take away the heat generated by the combustion in the cylinder, but also reduce the intake air temperature and optimize the combustion in the cylinder. Many cooling water pumps of internal combustion engines are driven by the crankshaft of the internal combustion engine, which can improve the energy efficiency of the internal combustion engine. Gear transmission is one of the most common ways to transmit power between the two. During the meshing process of two gears, The meshing clearance between gears is a very important parameter. Whether the backlash is normal or not is related to whether the gear can be accurately transmitted and whether it can run reliably and lastingly. If the clearance is too large or too smal...

Many cooling water pumps of internal combustion engines are driven by the crankshaft of the internal combustion engine, which can improve the energy utilization rate of the internal combustion engine, and gear transmission is one of the most common ways to transmit power between the two. During the meshing process of two gears, The meshing gap between gears is a very important parameter. Whether the backlash is normal or not is related to whether the gears can be transmitted accurately and can run reliably and permanently. Too large or too small gaps will cause abnormal wear of the gears.
