Description

Square plansifter transmission device self-loopa oil lubricating system
Technical field
The present invention relates to the lubricated of square plansifter transmission device, especially relate to a kind of square plansifter transmission device self-loopa oil lubricating system.
Background technique
Transmission device is to guarantee that square plansifter is by the driver element of setting the track running.In actual applications, bearing is the one of the main reasons that square plansifter lost efficacy because of lubrication problem breaks down.Existing lubricating system has two kinds: the one, and drier oil (lubricating grease) is lubricated.This mode is most widely used, and the square plansifter transmission device that domestic all square plansifter manufacturers and the most well-known international " Burl Corp " are produced all adopts the method.The square plansifter transmission structures is simple, short run effect is pretty good during actual the use, but because special installation form (installations of running shaft vertical) of square plansifter transmission device and service condition (integral hanging 24 hours uninterruptedly), long-time operational failure takes place frequently, its reason is that bearing lubrication is subjected to structural limitations, waste oil is discharged not smooth, difficult in maintenance.As changing lubricating grease or changing the bearing dismounting of whole transmission device all will being disintegrated.The 2nd, thin oil lubricant.It is in upper and lower bearing support bottom an oil storage pool to be set respectively, during operation, by disc oil has been got rid of and to enter bearing and be lubricated.At present, the square plansifter of " GBS " production adopts this structure.But since structural limitations, the bearing lubrication weak effect, and top also has oil leakage phenomenon to take place.
Summary of the invention
The object of the present invention is to provide the square plansifter transmission device self-loopa oil lubricating system that a kind of bearing lubrication cooling is abundant, rate of fault is low.
For achieving the above object, the present invention can take following technical proposals:
Square plansifter transmission device self-loopa oil lubricating system of the present invention comprises vertically disposed transmission rotational axis and transmission rotational axis is fixed on upper and lower bearing support on the frame that described transmission rotational axis is a hollow structure, and the lower end is provided with cam; The lower cover of described step extends to form an oil storage pool downwards, the piston that is fixed on the plunger-type fuel pump on the oil storage pool diapire boss is corresponding with described cam position, and the oil outlet of described plunger-type fuel pump covers the filler opening of offering on transport pipe and the upper bearing bracket on the frame and is connected by being arranged on; Upper and lower bearing support inner chamber is connected with the hollow cavity of transmission rotational axis by the upper and lower drainback passage that is opened on the transmission rotational axis sidewall.
The transmission rotational axis of described upper bearing bracket below is provided with the sealing oil return apparatus that is connected with the hollow cavity of transmission rotational axis, extends in the circular groove of sealing oil return apparatus with the lower cover of the upper bearing bracket of described transmission rotational axis Spielpassung.
Described circular groove inwall is provided with sealing blade and spiral oil-return groove.
Be set with on the transmission rotational axis of described step top and be communicated with the oil return cover of drainback passage and step inner chamber down, described oil return cover top is provided with Sealing, and the lower end is fixed by the step loam cake.
The invention has the advantages that self power that utilizes the square plansifter transmission rotational axis realizes that automatic cycle is lubricated, make the lubricated cooling of drive bearing fully, reduced rate of fault, improved the working life of bearing.
During the transmission device operation, end cam rotated under transmission rotational axis drove, and the work of cam actuated plunger oil pump is pressed into the upper bearing (metal) inner chamber with the lubricant oil in the oil storage pool by transport pipe upper bearing (metal) is lubricated; Then, lubricant oil enters the lower bearing inner chamber by last drainback passage, transmission rotational axis hollow cavity and following drainback passage lower bearing is lubricated, and gets back in the oil storage pool at last and moves in circles.
