Description

Technical Field

[0001] The utility model relates to the technical field of gear measurement, in particular to a detection tool for the clearance of idler gears of a noise-reducing automobile air compressor. Background Art

[0002] If the gap between the gears is too large when the air compressor is working, it will cause excessive noise and wear when the machine is working. However, if the installation is too tight, it will also cause large wear and damage to the gears. Therefore, the gear gap must be within an appropriate range.

[0003] For example, Chinese utility model patent CN217110768U discloses a device for measuring the tooth side clearance of a feed mechanism gear, which is connected by a positioning sleeve and a positioning hole. The sleeve is assembled with the main shaft through an angular contact ball bearing, a spacer ring 1 and an upper end cover, a lower end cover and a spacer ring 2 to replace the position of the reducer. The upper part of the main shaft is designed as a measuring rod and the measuring rod is engraved with lines to indicate the position of the gear pitch circle radius. By rotating the measuring rod, the actual value of the tooth side clearance between the standard gear and the rack can be measured.

[0004] However, it still has the following disadvantages: when the device needs to replace and detect gears of different sizes and formats, the gears to be detected cannot be replaced, making the detection model too single.

[0005] Based on this, the utility model designs a noise reduction type automobile air compressor idler gear clearance detection tool to solve the above problem. Utility Model Content

When the fixing is completed, the gear 2 is driven to rotate on the circular supporting plate by the driving detection component to measure whether the gear can operate normally. When the detection operation is completed, gas is injected into the air inlet on the support column to drive the pressing platform on the limit ring to move up along the cavity 2, and the locking ball is pressed into the circular groove by the upward movement of the cavity 2 to fix the gear 2.

By detecting the gap and operation of the gear 2, it can be determined whether the gear 2 can operate normally, so as to avoid the installation on the air compressor. The gap is too large to cause imaging pollution, or the gap is too small and too tight, so that the device is worn too much during operation.

[0021] 2. The utility model places gear 1 of the driving detection assembly on the motor. At this time, the threaded rod on the limit fixing column is rotated to compress the clamping column to move outward along the slot hole and contact the inner wall of gear 1 to clamp and fix gear 1. When gear 1 moves, it drives the limit plate to move and compresses the spring to contract. At this time, the output end of the driving detection assembly drives the motor to move, and the movement of the motor drives gear 1 to mesh with gear 2. At this time, the motor is started to drive gear 1 to rotate, and the rotation of gear 1 drives gear 2 to rotate to measure the running condition of gear 2. When it is necessary to replace gear 1 to measure gear 2 of different specifications, the threaded rod is rotated upward and the clamping column is no longer compressed. At this time, the spring pushes the limit plate and the clamping column to move and reset the contact to lock gear 1. The replacement is completed by moving gear 1 upward. By quickly replacing gear 1, gear 1 of different specifications can be replaced according to detection requirements, thereby meeting the detection of gear 2 of different models and improving the adaptability of the product.
