Abstract
A bucket rod steel sleeve comprises a bucket rod, a steel sleeve A, an oil filling hole B, a steel sleeve B, an oil filling hole A, shaft sleeves and hemicycle sleeves, and is characterized in that the steel sleeve A and the steel sleeve B are arranged on the bucket rod equidistantly; the oil filling hole A is formed in the middle part of the steel sleeve A; the oil filling hole B is formed in the middle part of the steel sleeve B; the hemicycle sleeves are arranged at the middle parts of the inner walls of the steel sleeve A and the steel sleeve B; the shaft sleeves are arranged at the two ends of each hemicycle sleeve respectively. The bucket rod steel sleeve has the benefits that as the oil filling holes are formed in the steel sleeves, lubricant adding is more convenient; the hemicycle sleeves are arranged at the middle parts of the inner walls of the steel sleeves, so that the storage space of lubricant is increased, the contact area of a rotating shaft and the shaft sleeves is reduced, the friction is reduced, oil storage troughs formed in the shaft sleeves can enlarge the oil storage space; spiral grooves are formed in the inner wall surfaces of the shaft sleeves, so that the lubricity between the shaft sleeves and the rotating shaft is effectively increased, the friction of the rotating shaft against the shaft sleeves is reduced, and the service lives of the shaft sleeves are prolonged.
Description
Technical field
The utility model relates to technical field of engineering machinery, more specifically says a kind of dipper steel bushing.
Background technique
In machinery, cause the wearing and tearing of part because of the long-term rotation meeting of axle, in the time that the gap of axle and hole in piece part may wear to a certain degree, just necessary renewal part, therefore uses steel bushing just can reduce the wearing and tearing of axle and part.Steel bushing also plays the centralized positioning of stationary axle, while not allowing it because of running, shakes and the effect of generation displacement.Because the rotation of axle produces friction, so need to be lubricated fully between axle and steel bushing, traditional steel bushing axle sleeve hole inwall is smooth, and lubricant oil cannot store after entering axle sleeve hole, need to add frequently lubricant oil, and lubrication effect is not fine; Meanwhile, the area of contact of axle and steel bushing is large, thereby frictional force is larger.
Summary of the invention
For addressing the above problem, it is convenient that the utility model has designed a kind of interpolation lubricant oil, inside can store lubricant oil, high lubricating effect improves the dipper steel bushing in working life, its technological scheme is: described dipper steel bushing is made up of dipper, steel bushing A, oil hole B, steel bushing B, oil hole A, axle sleeve, semicircle cover, it is characterized in that equidistant steel bushing A, the steel bushing B of being provided with on dipper, steel bushing A middle part is provided with oil hole A, steel bushing B middle part is provided with oil hole B, the inwall middle part of steel bushing A, steel bushing B is respectively arranged with semicircle cover, and the two ends of semicircle cover arrange respectively axle sleeve.
Oil hole A described in the utility model, is characterized in that oil hole A is step hole.
Oil hole B described in the utility model, is characterized in that oil hole B is step hole.
Axle sleeve described in the utility model, is characterized in that axle sleeve axle sleeve adopts 60Si2Mn material, and helical groove is set on inwall, and on the middle part inwall outer wall of axle sleeve, correspondence arranges oil storage tank, and the oil storage tank on inwall outer wall connects by through hole.
The beneficial effects of the utility model are the oil holes by arranging on steel bushing, improve the convenience of adding lubricant oil, inwall middle part at steel bushing arranges semicircle cover, increases the storage area of lubricant oil, reduces the area of contact of rotating shaft and axle sleeve, reduce friction, the oil storage tank arranging on axle sleeve can strengthen oil storage space, on the internal face of axle sleeve, helical groove is set, and can effectively increase the lubricity of axle sleeve and rotating shaft, thereby reduce the frictional force of axle sleeve, and improved the working life of axle sleeve.

embodiment:
By reference to the accompanying drawings 1, 2, 3, 4 pairs of the utility model describe in further detail, so that the public grasps implementation methods of the present utility model better, the utility model specific embodiment is: described dipper steel bushing is by dipper 1, steel bushing A 2, oil hole B 3, steel bushing B 4, oil hole A 5, axle sleeve 6, semicircle cover 7 compositions, it is characterized in that the equidistant steel bushing A 2 that is provided with on dipper 1, steel bushing B 4, steel bushing A 2 middle parts are provided with oil hole A 5, steel bushing B 4 middle parts are provided with oil hole B 3, steel bushing A 2, the inwall middle part of steel bushing B 4 is respectively arranged with semicircle cover 7, the two ends of semicircle cover 7 arrange respectively axle sleeve 6.
Oil hole A 5 described in the utility model, is characterized in that oil hole A 5 is for step hole.
Oil hole B 3 described in the utility model, is characterized in that oil hole B 3 is for step hole.
Axle sleeve 6 described in the utility model, is characterized in that 6 axle sleeves adopt 60Si2Mn material, and helical groove 6-2 is set on inwall, and on the middle part inwall outer wall of axle sleeve 6, correspondence arranges oil storage tank 6-1, and the oil storage tank 6-1 on inwall outer wall connects by through hole.
The beneficial effects of the utility model are the oil holes that arrange by steel bushing 1, improve the convenience of adding lubricant oil, inwall middle part at steel bushing 1 arranges semicircle cover 7, increase the storage area of lubricant oil, reduce the area of contact of rotating shaft and axle sleeve 6, reduce friction, the oil storage tank 6-1 arranging on axle sleeve 6 can strengthen oil storage space, helical groove 6-2 is set on the internal face of axle sleeve 6, can effectively increase the lubricity of axle sleeve 6 and rotating shaft, thereby reduce the frictional force of axle sleeve, and improved the working life of axle sleeve 6.
