Embodiment Construction

[0017] The present invention is described in detail below in conjunction with accompanying drawing.

[0018] refer to figure 1 , an axial limiting device for the planet carrier of a rotary planetary gearbox, including a limiting ring 2, which is installed in the slot processed on the left side of the upper tooth of the body 1, referring to figure 2 , image 3 , and the internal teeth 6 of the limit ring 2 are meshed with the external teeth 5 of the body 1, and the body 1 is engaged with the planetary carrier 4. The center line is aligned, and the limit ring 2 and the planetary carrier 4 are connected by bolts 3 after closing.

[0019] The number of internal teeth of the limiting ring 2 and the planet carrier 4 is z, and the inner tooth 6 of the limiting ring 2 is processed with a bolt connection hole at a rotation angle of 360° / z relative to the inner tooth of the planet carrier 4, for the bolt 3 Insert fixed.

Abstract

The invention provides an axial limiting device and method for a planet carrier of a rotary type planetary gearbox. A limiting ring is installed in a clamping groove machined in the left side of upper teeth of a machine body. Inner teeth of the limiting ring are meshed with outer teeth of the machine body. The machine body is meshed with the planet carrier. The tooth thickness and the tooth space center line of the limiting ring are both aligned with the tooth thickness and the tooth space center line of the machine body. The limiting ring and the planet carrier are combined and then connected through bolts. The planet carrier is clamped in the middle of the groove of the fixed machine body through the limiting ring with the inner teeth. The teeth of the limiting ring are arranged into the clamping groove along the tooth spaces of the machine body, the inner teeth of the limiting ring are circumferentially rotated by an angle relative to the outer teeth of the machine body, the teeth of the limiting ring are stopped by the outer teeth of the machine body, the limiting ring and the planet carrier of the low-speed level are connected through the bolts, and therefore the planet carrier of the low-speed level is axially limited. The axial limiting device has the advantages of being adjustable, good in floating stability and disassembly and assembly usability and the like. The axial limiting device is simple in structure, easy to machine, convenient to install, economical and convenient to use.

Description

technical field [0001] The invention is mainly applied to the occasion of axial limiting of the low-speed planetary frame of a rotary planetary gearbox, and particularly relates to an axial limiting device and method of a planetary frame of a rotary planetary gearbox. Background technique [0002] A rotary planetary gearbox whose basic component is a floating load equalizing mechanism needs to leave an axial clearance of 0.5-1.0mm between the two ends of each floating component and adjacent parts, otherwise, not only will the floating and load equalizing effects be affected , can also cause frictional heating and noise. [0003] The usual way to limit the axial limit of the low-speed planetary carrier is: to limit the axial limit of the planetary carrier through the end of the sun gear, or to fix the planetary carrier on the sun gear or the body with a circlip, Or the axial limit of the body to realize the axis limit of the planet carrier. However, in some special cases, i...
