Description
Technical field
The utility model relates to a kind of driving device of screw conveyor, the durable suspension bearing of particularly a kind of efficient energy-saving.
Background technology
At present, in the screw conveyor of transhipment, transmission article, its driving device adopts suspension bearing mostly, utilize the transmission of the step axle realizable force in ball-bearing casing and the ball-bearing casing central through hole, the step axle rotates in the ball-bearing casing central through hole, the friction that will rotate between the two makes ball-bearing casing endoporus bottom serious wear, thereby influences the service life of suspension bearing.A kind of energy-efficient durable suspension bearing is disclosed in Chinese patent CN2521432Y, for alleviating the frictional loss of step axle and ball-bearing casing endoporus, employing is provided with a circular groove on the face of cylinder at ball-bearing casing central through hole middle part, presetting lubricant in this circular groove is lubricated axle and ball-bearing casing, alleviate the worn-down effect although can play, but growth along with period of service, the lubricant consumption that is worn, withered rotten, make it lose lubricating effect, can not realize lubricating to axle and ball-bearing casing centre hole, the friction between them is increased, cause the serious wear of contact site between them, fragile ball-bearing casing, shorten the service life of suspension bearing, and its complex structure, parts are many, complexity is installed, increases cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of efficient energy-saving durable suspension bearing, can be lubricated at any time between the central through hole of its step axle and ball-bearing casing, reduce the wearing and tearing between them, high lubricating effect, ball-bearing casing is not fragile, improves the service life of suspension bearing, and simple in structure, parts are few, the material saving, cost is saved in easily assembling.
The utility model has adopted such technical scheme: the durable suspension bearing of a kind of efficient energy-saving, include the flat step axle of two end mills, there is the ball-bearing casing of annular oil groove at the central through hole middle part, the hanging axis bearing, the sealing enclosing cover that has the enclosing cover seal ring, it is characterized in that aforesaid ball-bearing casing central upper portion has dowel hole, annular oil groove on the bottom of this dowel hole and the aforementioned ball-bearing casing central through hole leads to, end in the ball-bearing casing central through hole is provided with step, be provided with on the outer ball-bearing casing of step one end exterior seal ring is arranged, the outer other end and the ball-bearing casing engagement that is covered on the ball-bearing casing central through hole of sealing, aforesaid hanging axis bearing middle part is provided with through hole with the dowel hole binding site of ball-bearing casing, be provided with screw thread locating dowel pin fuel filler pipe in the hanging axis bearing, the dowel hole engagement of aforementioned through-hole and ball-bearing casing is passed in the lower end of screw thread locating dowel pin fuel filler pipe.
The durable suspension bearing of efficient energy-saving that provides by the utility model, owing to be provided with screw thread locating dowel pin fuel filler pipe in the middle of the hanging axis bearing, this screw thread locating dowel pin fuel filler pipe lower end is connected with the dowel hole of ball-bearing casing, in use can be at any time by the lubricating oil of annotating in the annular oil groove of screw thread locating dowel pin fuel filler pipe on the ball-bearing casing central through hole, at any time guarantee lubricating between ball-bearing casing central through hole and the step axle, reduce the wearing and tearing between them, high lubricating effect, make ball-bearing casing not fragile, improve the service life of suspension bearing, and simple in structure, parts are few, the material saving, cost is saved in easily assembling.
