In order to realize the purpose, the loader double-variable assembly direct blocking shaft middle double-support structure comprises a sun gear, a first blocking planet carrier assembly, a direct blocking shaft, a thrust shaft sleeve, a direct oil blocking cylinder body, a bearing I, an inner spacer ring, an outer spacer ring and a bearing II; the sun gear is installed in the first-gear planet carrier assembly, the left end of the direct-gear shaft is inserted into the sun gear through spline fit, a first bearing and a second bearing are arranged in the middle of the direct-gear shaft, the first bearing and the second bearing are separated through an inner spacer ring and an outer spacer ring, and the first bearing and the second bearing are installed on the first-gear planet carrier assembly; the thrust shaft is sleeved at the right end of the direct blocking shaft, and the gap between the inner end surface of the right end of the direct blocking shaft and the thrust shaft sleeve is 0.2-2mm, so that long-time continuous friction of parts during operation is avoided; the direct baffle shaft is provided with a lubricating hole and a disassembling bolt hole, so that lubricating oil can be conveyed to the bearing I, the bearing II and the thrust shaft sleeve through the lubricating hole to improve the lubricating effect; the thrust shaft sleeve is arranged on the direct oil blocking cylinder.

The loader double-variable assembly direct blocking shaft middle double-support structure has the following technical characteristics and beneficial effects:

1. the first bearing and the second bearing are arranged in the middle of the direct blocking shaft, so that the direct blocking shaft is fully supported, the condition that one end of the direct blocking shaft is in spline fit and the other end of the direct blocking shaft is in bearing support to form a cantilever support structure in the prior art is avoided, the problem that the clutch is damaged due to the fact that the bearing is damaged easily in the actual use process is solved, and the product quality and the reliability are greatly improved.

2. Because the direct baffle shaft is provided with the lubricating hole and the dismounting bolt hole, lubricating oil can be conveyed to the bearing I, the bearing II and the thrust shaft sleeve through the lubricating hole, so that the lubricating effect is improved, and the product quality is improved; the direct fender epaxial dismantlement bolt hole is convenient dismantles the direct fender axle when overhauing, has improved the maintainability of product.

3. Because the clearance between the inner end face of the right end of the direct baffle shaft and the thrust shaft sleeve is set to be 0.2-2mm, long-term continuous friction of parts can not occur during operation, and the product quality is greatly improved.

4. The utility model discloses simple structure, reasonable in design, the facilitate promotion has obviously improved product quality and novelty, greatly increased the practicality.

Drawings

FIG. 1 is a schematic main sectional view of a double-variable assembly direct stop shaft middle double-support structure of a loader of the present invention;

reference numerals: the direct-drive type planetary gear set comprises a sun gear 1, a first-gear planetary carrier assembly 2, a direct-gear shaft 3, a thrust shaft sleeve 4, a direct-gear oil cylinder body 5, a first bearing 6, an inner spacer ring 7, an outer spacer ring 8 and a second bearing 9.

Detailed Description

The two middle supporting structures of the loader dual-variable assembly direct blocking shaft of the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, the loader double-variable assembly direct blocking shaft middle double-support structure of the present invention comprises a sun gear 1, a first blocking planet carrier assembly 2, a direct blocking shaft 3, a thrust shaft sleeve 4, a direct oil blocking cylinder body 5, a first bearing 6, an inner spacer ring 7, an outer spacer ring 8 and a second bearing 9; the sun gear 1 is installed in the first-gear planet carrier assembly 2, the left end of the direct-gear shaft 3 is inserted into the sun gear 1 through spline fit, a first bearing 6 and a second bearing 9 are arranged in the middle of the direct-gear shaft 3, the first bearing 6 and the second bearing 9 are separated through an inner spacer 7 and an outer spacer 8, and the first bearing 6 and the second bearing 9 are installed on the first-gear planet carrier assembly 2; the thrust shaft sleeve 4 is arranged at the right end of the direct blocking shaft 3, and the gap between the inner end surface of the right end of the direct blocking shaft 3 and the thrust shaft sleeve 4 is 0.2-2mm, so that long-time continuous friction of parts during operation is avoided; the direct baffle shaft 3 is provided with a lubricating hole and a disassembling bolt hole, so that lubricating oil can be conveyed to the bearing I6, the bearing II 9 and the thrust shaft sleeve 4 through the lubricating hole to improve the lubricating effect; the thrust shaft sleeve 4 is arranged on the direct oil blocking cylinder.
