Abstract

The invention relates to a gear and shaft assembling tooling, in particular to a tooling for accurate and quick assembling of a gear and a shaft, and belongs to the technical field of gear and shaft assembling. The gear and shaft assembling tooling comprises a base, wherein the center of the base is connected with a supporting block through bolts; an upper pressing plate and a lower pressing plate are jointly connected onto four sliding shafts, and the four sliding shafts are in sliding fit with the upper pressing plate and the lower pressing plate; the upper parts of the four sliding shafts are respectively provided with an upper restoring spring in a sheathing manner, the upper restoring springs are located between the upper pressing plate and the lower pressing plate and tightly press the upper pressing plate and the lower pressing plate, the lower parts of the four sliding shafts are respectively provided with a lower restoring spring in the sheathing manner, and the lower restoring springs are located between the lower pressing plate and the base and tightly press the lower pressing plate and the base. The gear and shaft assembling tooling has the advantages that the assembling is simple and quick to conduct, the production efficiency is improved, the tooling realizes accurate positioning, and the gear of a press-fit gear assembly is guaranteed not to run out during working; the lower restoring springs can prevent the workpiece and the tooling from being damaged due to compression, the overload protection is safe and parts are prevented from being damaged.

Description

technical field

[0001] The invention relates to a gear and shaft assembly tool, in particular to a tool for precise and quick assembly of a gear and a shaft, and belongs to the technical field of gear and shaft assembly. Background technique

[0002] Gear transmission is the most widely used form of transmission in mechanical transmission. Using gear transmission can transmit the transmission of one shaft to another shaft to achieve the purpose of speed change and direction change. There are generally two types of fit between gears and shafts: clearance fit and interference fit. When assembling the former, you only need to align the position and angle of the shaft and the gear and gently insert it, while the latter is more complicated, and there are hot and cold fitting methods. The heat-fitting method uses the principle of thermal expansion and cold contraction to enlarge the inner hole of the gear after heating and then assemble it with the shaft and then cool it. The col...
