Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] Parts of the invention are not drawn to actual size, and some dimensions have been exaggerated in relation to other relative dimensions to provide a clearer description and understanding of the invention.
[0015] Such as figure 1 and figure 2 Shown, embodiment of the present invention is as follows:
[0016] A gear tooth backlash detection device, comprising a marble platform (1), an autocollimating collimator (2), a right-angle plane mirror (3), a small lifting platform (4), an image acquisition monitor (5), and a gear A (6), gear B (7), gear tooling (8).
[0017] The marble platform (1) is used for installing the small lifting platform (4) and the gear tooling (8) to ensure a relatively stable relative positional relationship.
[0018] Gear A (6), gear B (7) are installed on the gear tooling (8), and ensure that gear A (6) can be fixed. ...

The invention provides a gear tooth side gap detection device and a gap calculation method. The two gears are fixed on the gear tooling, the self-collimating collimator is placed on a small lifting platform, and the right-angle plane mirror is placed on the center of the gear end surface. In the position, make the right-angle plane reflector align with the self-collimating collimator, and at the same time, the cross image can be observed on the image acquisition monitor. Turn the gear so that the two sides of the tooth surfaces of the two gears are in contact, and record the image on the image acquisition monitor at this moment. Cross azimuth deviation. The present invention does not rely on the lead pressing method and the meter-typing measurement method, and the measurement method of the present invention has simple structure, high measurement precision, and reduces the use cost. The detection method of the invention can strictly control the size of the gear tooth side clearance, effectively guarantee the service life of the product, has the characteristics of simple structure and high detection accuracy, and improves the production efficiency of the product.
Description
technical field [0001] The present invention relates to the field of precision mechanical assembly, especially a gear backlash detection device and calculation method during mechanical assembly. The present invention is mainly applied to photoelectric products. detection. Background technique [0002] When the gears mesh and drive, in order to form a lubricating oil film between the meshing tooth profiles and avoid gears from being stuck due to heat and expansion due to friction, there must be a gap between the tooth profiles. If the gap is too large, it will accelerate the gear tooth surface wear , affecting the stability of gear transmission. When assembling the gears of mechanical products, the lead pressing method and metering measurement method are usually used, which have complex structures and large measurement errors. In optoelectronic products, the requirements for gear meshing precision are relatively high. Contents of the invention [0003] In order to overco...
