Description
Technical field
The utility model relates to centrifuge field, particularly a kind of helical screens centrifuge differential shaft oil feeding device.
Background technology
Helical screens filtering centrifuge is widely used in the occasion of the Separation of Solid and Liquid such as chemical industry, pharmacy, it utilizes centrifugal force to go out outside machine by the liquid general entered in rotary drum, be trapped in solid in rotary drum and send outside machine by what there is certain speed discrepancy with rotary drum with spiral transferring, realize Separation of Solid and Liquid.Speed discrepancy is generally realized by mechanical differential mechanism, need the lubrication of lubricating oil in the course of the work, what present most centrifuge adopted is that then a cover with sealing ring and bearing is sleeved on differential input shaft end, easily cause bad seals leakage of oil owing to there is error in manufacture process, and after differential input shaft wearing and tearing, replacement cost is increased, to install and remove workload large.
Summary of the invention
The purpose of this utility model will solve the problems of the technologies described above.
The purpose of this utility model is achieved in that a kind of helical screens centrifuge differential shaft oil feeding device, comprise differential input shaft, differential input shaft is disposed with from right to left right belt wheel, left belt wheel and adapter sleeve, adapter sleeve and differential input shaft contact surface are provided with sealing ring a, it is characterized in that: described left belt wheel is fixed on differential input shaft by flat key, left belt wheel left side is provided with concave surface, left belt wheel concave surface has been bolted adapter sleeve, the contact surface of adapter sleeve and left belt wheel is provided with sealing ring b, the adapter sleeve left side is connected with straight coupling, straight coupling left end is connected with swivel joint, swivel joint periphery is provided with damping sleeve, damping sleeve periphery is wrapped in fixed cover, swivel joint is connected with oil inlet pipe, fixed cover and damping sleeve are bolted on bracket, bracket is provided with circular hole.
Described differential input shaft is set to stairstepping, and differential input shaft is provided with keyway, and differential input shaft is provided with oil groove.
Described adapter sleeve is set to shape for hat, and shade top is provided with concave surface, and shape for hat top is provided with Internal Pipe Thread, and adapter sleeve inside is provided with seal groove.
Described damping sleeve and fixed cover is supporting is set to L-type circulus.
The utility model is rational in infrastructure, and practical reliable, mounting or dismounting are simple, extend service life, improve production efficiency, reduce maintenance cost.Lubricating oil of the present utility model enters in swivel joint from oil inlet pipe under the effect of pump; and the oil groove entered into by adapter sleeve in differential input shaft; swivel joint by damping sleeve and fixed cover spacing in bracket circular hole; left belt wheel can absorb the vibration brought due to machine vibration or concentricity in the process of running up, thus protects the service life of swivel joint.
Accompanying drawing explanation
