Description
Technical field
The present invention relates to speed reducer field, be specifically related to a kind of self-lubricating speed-reducing machine of oil-leakage-prevention.
Background technique
In speed reducer field, for the speed reducer run up, because rotating shaft rotating speed is comparatively large, the heating value of bearing is large, needs oil lubrication and the ventilative cooling of Ventilated cap.Existing more common lubricating system is selflubricating, is namely thrown away by oil in rotation process by gear, and after being collected by the oil thrown away, guide bearing lubricates.The defect that such lubricating system exists usually is, because bearing is also in high speed rotating, lubricant oil can throw away to axle head and overflow from the oil sealing of bearing (ball) cover by bearing, pollutes.The oil that part throws away simultaneously easily spills in Ventilated cap, pollutes and wastes.
Summary of the invention
For solving deficiency of the prior art, the object of the present invention is to provide a kind of self-lubricating speed-reducing machine of oil-leakage-prevention.
The technological scheme that the present invention takes is:
A kind of self-lubricating speed-reducing machine of oil-leakage-prevention, comprise casing, case lid and Duo Gen rotating shaft, rotating shaft is connected to casing, case lid is installed on the top of casing, before described casing, rear box wall is equipped with bearing hole, in bearing hole, bearing is installed, the outer wall of casing is provided with the bearing (ball) cover covering bearing hole, rotating shaft be supported at both ends in brearing bore and cross-under bearing (ball) cover, through oil sealing sealing between rotating shaft and bearing (ball) cover, rotating shaft is provided with gear, the inwall of described case lid is provided with oil trap, the bottom of oil trap is provided with the passage leading to bearing hole, oil baffle is provided with in described bearing hole, described oil baffle is serially connected with rotating shaft, oil baffle is arranged between bearing and bearing (ball) cover, the top of the sidewall of described case lid is provided with bend pipe Ventilated cap.
Further, described Ventilated cap comprises bend pipe and cap body, and bend pipe is vertically installed on the top of case lid sidewall, and cap body is installed on the top of bend pipe, and the inner side of described cap body is provided with the curved channel in UNICOM's bend pipe and outside.
Again further, be provided with baffle plate above together in described bend pipe, multiple tracks baffle plate forms broken line passage in bend pipe, and spaced barrier is established in the bottom surface of described baffle plate.
After taking above technological scheme, beneficial effect of the present invention is:
1. bearing (ball) cover, bearing machine bearing hole form a cavity, guide to bearing lubrication in chamber by the mode of selflubricating by oil, getting rid of oil spill and going out, between bearing and bearing (ball) cover, arranging oil baffle for avoiding bearing, are blocked by the oil that gets rid of of bearing, effectively avoid leaking;
2. adopt bent-tube boiler Ventilated cap, relative straight tube bend pipe is bending channel, and the inner side of bend pipe is provided with multiple baffle plate, baffle plate forms broken line passage in bend pipe, and the bottom surface of baffle plate is provided with barrier, when have spatter to baffle plate time, barrier has individual playing to cushion and leading role, the reflection avoided and splashing; Above technological scheme combines can more effectively avoid spilling of lubricant oil.
