Description

TECHNICAL FIELD

[0001] The utility model relates to gear technical field especially relates to a full gear clearance measuring device convenient to use. BACKGROUND

[0002] Gear is a kind of mechanical transmission element, mainly used for transmitting power and rotating speed. Gear is made of circular gear teeth of equal number of teeth, and the transmission of power and rotating speed is realized by the meshing between gears. Each gear has a central axis, and the meshing between gears is carried out between two central axes. When the gear rotates, the meshing between gears makes another gear also rotate, thereby realizing the transmission of power and rotating speed.

[0003] When gears are used, at least two gears are needed to engage, at this time, if the produced gears and design parameters differ greatly, the gears engaged with each other will have a gap, if the gear with gap continues to work, many problems will occur, 1. Transmission efficiency is reduced: gear transmission gap will cause relative sliding of gears during transmission, thereby reducing transmission efficiency and increasing transmission loss; 2. Noise increases: gear transmission gap will cause impact of gears during transmission, thereby increasing transmission noise and affecting normal operation of mechanical equipment; 3. Wear is aggravated: gear transmission gap will cause additional load of gears during transmission, thereby aggravating wear of gears and shortening service life of mechanical equipment; 4. Transmission accuracy decreases: when gear meshing gap is too large, transmission accuracy will decrease, resulting in inaccurate transmission and affecting performance and stability of mechanical equipment.

[0004] The traditional detection method is to determine the center and radius of the circle by three points. This detection method is not accurate enough, and it is very difficult to measure, for example, the division circle and the root circle. The division circle cannot be directly measured, so the traditional manual detection method cannot truly reflect the parameters of the processed gear, and therefore cannot guarantee the gap between the engaged gears.
