Embodiment 1

[0021] like figure 1 As mentioned above, the hob spindle of the gear hobbing machine in this embodiment includes: a torque input component, a hob installation component, and an auxiliary support component, wherein the torque input shaft is located on the left, and the auxiliary support component is located on the right.

[0022] The torque input components include a synchronous pulley 1, a first lock nut 2, a torque input shaft key 3, a spacer 4, a torque input shaft 11, a first angular contact ball bearing 7, a second angular contact ball bearing 12, Input shaft bearing seat 8, first sealing ring 6, second sealing ring 14, first bearing end cover 5, second bearing end cover 13, large bearing adjustment sleeve 9, small bearing adjustment sleeve 10, elastic collet of torque input shaft 15 and the first pressure cap 16 used in conjunction with the elastic collet, wherein the torque input shaft elastic collet 15 is installed at one end of the torque input shaft 11, the first l...

Embodiment 2

[0043] like figure 2 As shown, the torque input part and the auxiliary support part in this embodiment are the same as those in Embodiment 1. The hob installation shaft key 32 is set on the hob installation shaft 17, and the keyway is milled out on the hob installation shaft 17. The hob installation shaft The key 32 is placed in the keyway, and the hob installation shaft 17 transmits torque to the hob 18 through the hob installation shaft key 32, which is more convenient for loading and unloading, and has good centering.

Embodiment 3

[0045] like image 3 As shown, the hob installation part and the auxiliary supporting part in this embodiment are the same as in Embodiment 1, and the synchronous pulley 1 in the torque input part is replaced by a gear 33 .

Abstract

The invention provides a quick-changing type hob main shaft of a gear hobbing machine. The quick-changing type hob main shaft is simple in structure, can quickly replace a hob, and comprises a torque input component, a hob installation component and an auxiliary support component. According to a hob installation shaft, only the installation of the hob needs to be considered. The hob installation shaft is provided with no bearing and no torque transmission element, thereby being simple in structure, and convenient to machine. The hob and the hob installation shaft are convenient to replace, and the quick-changing type hob main shaft is suitable for single unit processing or small batch processing of various small module gears. An auxiliary support shaft only bears friction torque generated by a bearing and a sealing ring on the torque respect, and the friction torque is small, and therefore the auxiliary support shaft is small in torsional deformation.

Description

technical field [0001] The invention relates to a gear hobbing machine, in particular to a hob spindle structure of the gear hobbing machine. Background technique [0002] The hob of the current gear hobbing machine is installed on the torque input shaft. If a hob with a different inner diameter is used, the torque input shaft must be replaced. Because the torque input shaft needs to be installed with transmission, support, sealing and other parts, the structure of the torque input shaft is complicated, the workload of replacing the torque input shaft is large, and the processing cost of the torque input shaft is high. Therefore, this hob installation method is not suitable for multi-variety, single-piece or small-batch gear processing. Publication number is CN102059408A patent, needs hydraulic cylinder to provide power when replacing hob cutter bar, must have a set of hydraulic system, so equipment is complicated, and cost is also higher. Contents of the invention [00...
