Curved bevel pinion and bevel gear assembly have higher requirements on the center distance and cutting depth. The frequency of the tooth tip is too thin and the small end is damaged. The load capacity of the gear transmission is significantly reduced during operation, which causes the gear to break. Secondary reason. Curved bevel gears are suitable for conveying stable, high-speed, heavy-duty working environments, while curved bevel gears are not well adapted to the high-impact and frequent, low-speed and medium-load conditions of our stacker and reclaimer. This is another cause of damage to the gear.
The assembly precision of the high-speed bushing of the bucket wheel is improved, the geometric parameters of the same-travel curve bevel gear are controlled, the two-axis intersection angle, the scraping tile, the padding and the like are ensured, but the use effect is not satisfactory, and the gear tooth breakage phenomenon is still serious. The feasibility analysis of replacing the curved bevel gear aluminum ladder with straight bevel gear, for the actual working condition of the stacker and reclaimer, under the conditions of ensuring the transmission requirements, working load and assembly form, the automobile lubricant is economic and objective. Practical and best principles, it was decided to redesign the spiral bevel gear transmission as a straight bevel gear transmission. The straight bevel gear transmission has the characteristics of resistance to shock, low speed and medium load, which is suitable for the stacker and reclaimer bucket wheel system. First analyze the feasibility of the structure.
According to the structure of the high-speed part of the original design of the bucket wheel reducer, the geometry of the straight bevel gear is redesigned. The geometrical dimension of the straight bevel gear and the curved bevel gear (axis angle Σ=90°) can be compared from the geometric size comparison table. It can be seen that there is no change in the external dimensions of the two gear drives, the main difference being the gearing and the accuracy level. The straight bevel gear with low precision grade is mainly to solve the problem that it is difficult to install and difficult to debug at the site. The design also satisfies the site structure requirements of the bucket wheel system transmission.
