Description
Technical Field
The utility model relates to the technical field of mechanical parts, in particular to a roller assembly structure.
Background
The anchoring drilling machine and other machines need to be pulled by a chain wheel, a roller assembly is usually adopted, the rotation stability of the existing roller assembly is poor, and the chain inclination is easy to generate, so that the pulling effect is influenced, and more importantly, safety accidents can be generated.
Disclosure of Invention
Aiming at the technical problems, the utility model provides the roller assembly structure which is simple in structure and can well ensure the stability of chain traction, thereby ensuring the traction effect and effectively preventing safety accidents.
The technical scheme is as follows: the utility model provides a roller assembly structure, its includes the axle, the epaxial cover is equipped with rotatory guide pulley, rotatory guide pulley passes through the bearing and connects the axle, its characterized in that: the rotary guide wheel is connected with the shaft through two bearings, and the two bearings are respectively arranged at two ends of the shaft.
The bearing assembly is further characterized in that a spacer is arranged between the two bearings, and two sides of the spacer are respectively abutted against the two bearings; an annular groove is formed in the shaft, and the spacer bush part is arranged in the annular groove; bearing covers are respectively arranged on the outer sides of the two bearings, and oil seals are arranged on the bearing covers; the spacer bush is provided with an oil groove which is connected with the oil inlet hole.
According to the utility model, due to the adoption of the structure, the rotating guide wheel is connected with the shaft through the two bearings, the two bearings are respectively arranged at the two ends of the shaft, so that the rotating stability of the rotating guide wheel is ensured, the chain is sleeved on the rotating guide wheel and driven to rotate by the idler wheels, the stability of chain traction is better ensured, the traction effect is ensured, and the occurrence of safety accidents is effectively prevented.
Drawings
FIG. 1 is a schematic diagram of a roller assembly according to the present utility model.
Detailed Description
The utility model will be further described with reference to the drawings and examples.
See fig. 1, a roller assembly structure, it includes axle 1, and axle 1 is gone up the cover and is equipped with rotatory guide pulley 2, and rotatory guide pulley 2 passes through two bearings 3-1, 3-2 connecting axle, and two bearings 3-1, 3-2 set up respectively at the both ends of axle 1, because rotatory guide pulley is supported on the axle through both ends bearing, has effectively guaranteed rotatory guide pulley pivoted stability.
A spacer bush 4 is arranged between the two bearings 3-1 and 3-2, two sides of the spacer bush 4 are respectively abutted against the two bearings 3-1 and 3-2, so that the axial movement of the bearings is prevented, and the rotating stability of the rotating guide wheel is further ensured.
The annular groove 5 is arranged on the shaft 1, and the spacer bush 4 is partially arranged in the annular groove 5, so that the axial positioning of the spacer bush is ensured, and the rotating stability of the rotating guide wheel is ensured.
The stability of chain traction is guaranteed through guaranteeing the stability of rotation of the rotary guide wheel, so that the traction effect is guaranteed, and safety accidents are effectively prevented.
Bearing caps 6-1 and 6-2 are arranged on the outer sides of the two bearings 3-1 and 3-2 respectively, oil seals 7-1 and 7-2 are arranged on the bearing caps, and the bearing caps are connected with the shafts through the oil seals, so that the sealing of the roller assembly structure is ensured, the lubricating oil is prevented from overflowing, the lubrication between the bearings and the shafts is ensured, the abrasion of each part in the roller assembly structure is reduced, and the service life of the whole roller assembly structure is effectively prolonged.
The oil groove 8 is arranged on the spacer bush 4 and is connected with the oil inlet hole 9, so that lubrication between the shaft and the main shaft is ensured.
The present utility model and its embodiments have been described above by way of illustration and not limitation, and the embodiments of the present utility model shown in the drawings are not limited thereto, and the actual structures are not intended to be within the scope of the present utility model unless they depart from the spirit of the utility model.
