Abstract
The utility model discloses a full-lubrication structure of a sprocket shaft. The full-lubrication structure comprises a shaft as well as a fixed sleeve and a lining which are sheathed on the shaft in sequence, wherein an axial oil hole and a radial oil hole which are communicated with each other are formed in the shaft, an annular oil groove corresponding to the radial oil hole is arranged on the surface of the shaft, a through oil hole corresponding to the annular oil groove is formed in the fixed sleeve, an internal spiral oil groove is arranged in the inner surface of the fixed sleeve, and an internal spiral oil groove is arranged in the inner surface of the lining. The full-lubrication structure is simple and durable, is strong in adaptive capacity to environment, and is good in lubrication effect, the lubrication of all contact surfaces can be ensured, the effective and entire lubrication to the sliding contact surfaces by oil can be achieved, and continuous and high-efficiency running of a chain can be ensured. In addition, oil enters from the end of the shaft and flows from the middle to two ends of the shaft, the fixed sleeve and the lining so as to extrude impurities such as dust in the contact surfaces out, ensure the cleanness of the contact surfaces and play a role in preventing immersion of dirt.
Description
Technical field
The utility model belongs to the conveying equipment technical field, particularly the full lubricating structure of a kind of sprocket shaft.
Background technique
At present, the drag conveyor technology is day by day ripe, in the solid material conveyor line of every profession and trade, has become most popular conveying equipment at home.Chain device is as the key position of drag conveyor, and its sprocket shaft structure is its core.
Because sprocket shaft is lubricated bad, makes chain greasisng not in place, adds the impact of environment, causes drag conveyor often to go wrong, for example the chain roller damages, and has greatly increased the frequency of changing, and has increased operating cost; And the chain after the heavy wear easily derailing causes cancel closedown.
The model utility content
The purpose of this utility model has provided the full lubricating structure of sprocket shaft of the strong and high lubricating effect of a kind of simple in structure, durable in use, adaptive capacity to environment.
For achieving the above object, the technical solution of the utility model is: the full lubricating structure of a kind of sprocket shaft, comprise on axle and the axle sheathed successively fixed cover and lining, be provided with the axial oilhole and the radial direction oil hole that communicate in the axle, described axle surface is provided with the annular oil groove corresponding with radial direction oil hole, fixed cover is provided with the oil through corresponding with annular oil groove, and the fixed cover internal surface is provided with the spiral oil groove, and sleeve inner surface is provided with the spiral oil groove.
Described axial oil outer end of hole is provided with forced filling oil cup.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises on axle and the axle sheathed successively fixed cover and lining, be provided with the axial oilhole and the radial direction oil hole that communicate in the axle, described axle surface is provided with the annular oil groove corresponding with radial direction oil hole, fixed cover is provided with the oil through corresponding with annular oil groove, the fixed cover internal surface is provided with the spiral oil groove, sleeve inner surface is provided with the spiral oil groove, it is simple in structure, durable in use, adaptive capacity to environment is strong, high lubricating effect, the specific works process is: by oil gun to the forced filling oil cup grease adding; Grease enters in the annular oil groove of axle by axial oilhole and radial direction oil hole, and a part of grease enters the spiral oil groove of fixed cover along annular oil groove, and another part grease enters the sliding contact surface between the lining of fixed cover and rotation by oil through; Sleeve inner surface is provided with the spiral oil groove, final grease is full of and permeates the spiral oil groove of lining and the sliding contact surface of fixed cover and lining, guarantee the lubricated of all surface of contact, grease is reached effectively and comprehensively sliding contact surface lubricate, guarantee that chain continues efficiently operation.In addition, grease enters from shaft end, finally flows to two ends from the middle part of axle, fixed cover and lining, the impurity such as dust in the surface of contact can be extruded, and guarantees the surface of contact cleaning, plays the effect that prevents that dirt from immersing.
2, the utility model can guarantee effectively that sprocket wheel steadily rolls in orbit, can effectively reduce the transmission resistance, reduces maintenance cost, prolong chain working life, can greatly improve equipment to the adaptive capacity of working environment, improve the performance of drag conveyor, reach energy-saving and cost-reducing purpose.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The full lubricating structure of sprocket shaft as depicted in figs. 1 and 2, it comprises on axle 1 and the axle 1 sheathed successively fixed cover 2, lining 3 and sprocket wheel 4, with draw-in groove, fixed cover 2 is provided with flat side on the axle 1, is convenient to install.In axle 1, be provided with the axial oilhole 6 and the radial direction oil hole 7 that communicate, be provided with the forced filling oil cup 5 that communicates with axial oilhole 6 at axle 1 end face.Be provided with the annular oil groove 8 corresponding with radial direction oil hole 7 on the surface of axle 1, fixed cover 2 is provided with the oil through 10 corresponding with annular oil groove 8, and fixed cover 2 internal surfaces are provided with spiral oil groove 9, and the internal surface of lining 3 is provided with spiral oil groove 11.
In the present embodiment, fixed cover 2 is wear-resisting steel bushing, and lining 3 is the copper alloy bushing of high bearing capacity.
The utility model working principle is: by oil gun to forced filling oil cup 5 grease addings; Grease enters in the annular oil groove 8 of axle 1 with radial direction oil hole 7 by axial oilhole 6, part grease enters the spiral oil groove 9 of fixed cover 2 along annular oil groove 8, and another part grease enters sliding contact surface between fixed cover 2 and the lining 3 that rotates by oil through 10; Lining 3 internal surfaces are provided with spiral oil groove 11, final grease is full of and permeates the spiral oil groove 11 of lining 3 and the sliding contact surface of fixed cover 2 and lining 3, guarantee the lubricated of all surface of contact, grease is reached effectively and comprehensively sliding contact surface lubricate, guarantee that chain continues efficiently operation.In addition, grease enters from axle 1 end, finally flows to two ends from the middle part of axle 1, fixed cover 2 and lining 3, the impurity such as dust in the surface of contact can be extruded, and plays the effect that prevents that dirt from immersing.
