Abstract
The utility model relates to a cone gear support mechanism in the gear box of the agricultural machinery. The utility model provides the cone gear support mechanism having the advantages of low manufacture cost, simple structure, convenient mounting adjustment, wear resistance and strong carrying capacity. A group of shaft sleeves and a thrust bearing are together sheathed on a stepped shaft, and adjusting shims are arranged in front of the stepped shaft of the shaft hole of a box body. The support mechanism can fully bear the axial force and the radial force which are generated in the engaging process of a cone gear pair, improves the lubricated condition, conveniently adjusts the engaging gap and enhances the carrying capacity and the service life.
Description
The utility model relates to the supporting device of garden bevel gear in a kind of agriculture harvesting and tillage machine tool gear-box.
Garden bevel gear supporting device in the existing gear-box, general semiaxis or the axis of adopting supported by bearing, and its assembly precision and bearing capacity all require very high, adds that bevel gear back lash, garden is difficult for adjusting, reduce the transmission accuracy of gear, directly influenced serviceability and life-span.
The purpose of this utility model provides a kind of low cost of manufacture, and is simple in structure, install easy to adjust, wear-resisting and garden bevel gear supporting device that bearing capacity is strong.
For achieving the above object, the utility model adopts structural principle as shown in the figure: axle sleeve (1,4) press-fits in garden bevel gear (2) endoporus two ends, be enclosed within jointly on the step axle (6) with thrust bearing (5), the step axle (6) that adjusting pad (8) is installed in casing (7) hole is preceding.
Owing to take such scheme, the physical dimension of axle sleeve (1,4) can be very little and can guarantees its required precision easily, thereby can satisfy the requirement of strength of garden bevel gear (2) and step axle (6) to greatest extent.Simultaneously, owing in the axle sleeve (1,4) helical oil groove is arranged, can guide flowing of lubricating oil better, strengthen radiating effect and contamination resistance, the oil film of formation can improve its bearing capacity effectively and reduce wearing and tearing.
For the back lash of garden bevel gear (2) in assembling and the generation of wearing and tearing back, adjust the axial location of step axle (6) by increase and decrease adjusting pad (8) and outside casing, just can finish easily, avoided the pollution of mounting or dismounting to lubricating oil.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure chart of the utility model embodiment.
Among the figure 1, axle sleeve 2, garden bevel gear 3, spur gear 4, axle sleeve 5, thrust bearing 6, step axle 7, casing 8, adjusting pad
Among the figure, the axle sleeve (1,4) that has helical oil groove is respectively charged into garden bevel gear (2) endoporus two ends, is enclosed within jointly on the step axle (6) with thrust bearing.
Preceding according to the step axle (6) that the engagement of garden bevel gear pair selects the adjusting pad (8) of suitable thickness to be installed in the axis hole of casing (7).
Claims (3)
1, the supporting device of garden bevel gear in a kind of gear-box, it is characterized in that axle sleeve (1,4) garden bevel gear (2) the endoporus two ends of packing into, be enclosed within jointly on the step axle (6) with thrust bearing (5), before adjusting pad (8) is installed on step axle (6) head in the axis hole of casing (7).
2, the supporting device of garden bevel gear in the gear-box according to claim 1 is characterized in that: step axle (6) is the reducing axis.
3, the supporting device of garden bevel gear in the gear-box according to claim 1 is characterized in that: axle sleeve has helical oil groove in (1,4).
