Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0020] Such as Figure 1 to Figure 5 As shown, a gear grinding tool for planetary gears includes a shaft core 1, on which a support pad 2, a gland 3 and a No. 2 and the gland 3, and the planetary gear 5 is set on the shaft core 1, the support pad 2 and the No. 1 fixing nut 4 are both threaded with the shaft core 1, and the shaft core 1 is provided with a number of circumferentially uniform axial cones. Strip groove 7, tapered strip 6 is matched in the tapered strip groove 7, the end of the tapered strip 6 away from the shaft core 1 is located between the two adjacent teeth on the inner side of the planetary wheel 5, and the upper end of the tapered strip 6 is provided for pressing The second fixed nut 8 of the tapered strip 6 and the planetary wheel 5 is threadedly connected with the shaft core 1 .

[0021] A No. 1 gasket 9 is provided between the No. 1 fix...

Abstract

The invention provides a planet gear grinding tool. The planet gear grinding tool comprises a shaft core. The shaft core is sequentially sleeved with a supporting pad, a gland and a first fixing nut from bottom to top, a plurality of axial conical strip grooves which are evenly distributed in the circumferential direction are formed in the shaft core, conical strips are arranged in the conical strip grooves in a matched mode, and the ends, away from the shaft core, of the conical strips are located between every two adjacent teeth on the inner sides of planet gears; and second fixing nuts usedfor pressing the conical strips and the planet gears are arranged at the upper ends of the conical strips and are in threaded connection with the shaft core. The conical strips are pressed through the second fixing nuts, and the conical strips are synchronously expanded outwards, so that the centering and fastening effects are achieved, the gland is pressed through the first fixing nut, the planet gears cannot move in the axial direction, and a gear grinding machine is used for machining after installation is completed. The conical strips are used for replacing expansion sleeves, so that theproblem that the expansion sleeves are prone to breakage is solved. In addition, the planet gears are convenient to install, and the problem that clamping is difficult in the gear grinding machining process is solved.

Description

technical field [0001] The invention relates to the technical field of planetary gear processing, in particular to a planetary gear grinding tool. Background technique [0002] In the field of planetary gear processing technology, it is necessary to grind the planetary gear. The existing common planetary gear grinding tooling adopts single-sided or double-sided expansion sleeves for processing. However, there are workpiece jamming during the gear grinding process. Difficult, the problem that the expansion sleeve is easy to break. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a planetary gear grinding tool. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a planetary gear grinding tool, including a shaft core, which is covered with a support pad, a gland and a No. 1 fixing nut in sequence from bottom to top, and several planetary gears stacked up a...
