Abstract
The utility model relates to a self-pressure type reverse gear shaft lubricating device which comprises a reverse gear shaft body. The device is characterized in that one end of the reverse gear shaft body is provided with a blind hole along the axial direction; the peripheral wall of the blind hole is provided with an oil inlet and an oil outlet which are formed in a front and back staggered way; furthermore, the oil inlet and the oil outlet are respectively communicated along the radial direction. Compared with the prior art, the self-pressure type reverse gear shaft lubricating device has the advantages that the shaft body is provided with the through holes and the blind hole, so that an oil way channel can be formed, lubricating oil can enter a box body provided with the shaft body through the oil way channel, and the interior of the box body can be lubricated; the lubricating structure is not influenced by the rotating speed, and the more sufficient oil can enter the box body, so that the box body is comprehensively and effectively lubricated.
Description
Technical field
The utility model relates to a kind of lubricating fitting, particularly a kind of lubricating fitting of tractor self-pressure type reverse gear shaft.
Background technique
As shown in Figure 3, lubricating fitting structural representation for self-pressure type reverse gear shaft of the prior art, on the periphery wall of this reverse gear shaft 1 ', offer spiral chute 2 ', after reverse gear shaft is assembled in casing, lubricant oil is splashed on spiral chute after rotating by axle, and then flow into and in casing, realize lubrication effect through spiral chute 2 '.This lubricating structure is because need the power producing by splashing could realize lubricated, its lubrication effect is poor, and in the situation that flank speed degree is not high, the lubricant oil entering in casing is few, lubricated object comprehensively cannot be arrived, thereby working efficiency and the working life of complete machine can be affected.
Model utility content
Technical problem to be solved in the utility model is that the lubricating fitting of the better self-pressure type reverse gear shaft of a kind of lubrication effect is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of lubricating fitting of self-pressure type reverse gear shaft, include reverse gear shaft body, it is characterized in that: one end of described reverse gear shaft body offers blind hole vertically, the oil inlet hole and the oil outlet that before and after the periphery wall of this blind hole offers, stagger and arrange, and described oil inlet hole and oil outlet radially connect respectively.
As preferably, described reverse gear shaft has minor diameter part and large-diameter portion, between described minor diameter part and large-diameter portion, form ladder surface, described blind hole is axially offered along large-diameter portion from the end of described minor diameter part, described oil inlet hole is opened on the outer wall of described minor diameter part, and described oil outlet is opened on the outer wall of described large-diameter portion.
As further preferred, the central shaft of the central shaft of described blind hole and described reverse gear shaft body overlaps.
As preferably, the afterbody of described reverse gear shaft body also offers the tapped hole that can coordinate with fastening piece.
Compared with prior art, the utility model has the advantage of: by offering through hole and blind hole to form asphalt channel on axle body, lubricant oil can be entered in the casing that this axle body is installed by this asphalt channel, realization is lubricated to box house, this lubricating structure is not subject to the impact of rotating speed, make box house oil-feed more abundant, guaranteed the lubricated comprehensively and effectively of casing.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's partial structurtes sectional view.
Fig. 2 is that the A-A shown in Fig. 1 is to sectional view.
Fig. 3 is reverse gear shaft lubricating fitting structural representation of the prior art.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Fig. 1～Fig. 2, the present embodiment discloses a kind of lubricating fitting of self-pressure type reverse gear shaft, and this reverse gear shaft includes reverse gear shaft body 1, and one end of reverse gear shaft body 1 offers blind hole 2 vertically, and the central shaft of the central shaft of blind hole 2 and reverse gear shaft body 1 overlaps; The oil inlet hole 31 and the oil outlet 32 that before and after the periphery wall of blind hole 2 offers, stagger and arrange, and oil inlet hole 31 and oil outlet 32 radially connect respectively; The afterbody of reverse gear shaft body 1 also offers the tapped hole 4 that can coordinate with fastening piece.
Wherein, reverse gear shaft body 1 has minor diameter part 11 and large-diameter portion 12, between minor diameter part 11 and large-diameter portion 12, forms ladder surface, and blind hole 2 is axially offered along large-diameter portion 12 from the end of minor diameter part 11, oil inlet hole 31 is opened on the outer wall of minor diameter part 11, and oil outlet 32 is opened on the outer wall of large-diameter portion 12.So, between oil inlet hole 31 and oil outlet 32, form an asphalt channel, lubricant oil can and then be lubricated box house through this asphalt channel, guarantees that lubricant oil fully enters into casing, reach better lubrication effect, improve the performance and used life of complete machine.
