Abstract

The utility model discloses an end cover with the oil guiding function for a cross axle type universal coupler. An annular boss used for positioning a thrust bearing is arranged in the center of the inner side of the end cover body; a plurality of oil grooves are uniformly formed in the periphery of the annular boss of the inner side of the end cover body in the radial direction; a plurality of diversion trenches communicated with the oil grooves in a one-to-one manner are formed in the outer wall of the annular boss; an annular groove is formed in the inner side of the end cover body; the diameter of the annular groove is slightly larger than that of a thrust bearing; the oil grooves are communicated with the annular groove. The end cover provided by the utility model is reasonable and ingenious in design; through the adoption of the utility model, most of the oil, which previously flows from the oil groove in the thrust bearing to the lubricating part of the radial bearing, flows from the oil grooves in the inner side of the end cover to the lubricating part of the radial bearing, thereby fully lubricating the radial bearing and the thrust bearing under the work condition and prolonging the service lives of the radial bearing and the thrust bearing.

Description

The end cap with Oil Guide function for universal coupling with spider
Technical field
The utility model belongs to Hooks coupling universal coupling technical field, relates in particular to the end cap with Oil Guide function for a kind of universal coupling with spider.
Background technique
Universal coupling with spider is a kind of the most frequently used coupling, utilizes the feature of its structure can make not at same axis or axis knuckle large or move axially larger diaxon isogonism speed continuous rotary, and transmitting torque and motion reliably.At present, be widely used in transmitting torque in the mechanical axis system of metallurgy, lifting, engineering transportation, mine, oil, boats and ships, coal, rubber, papermaking equipment and other Heavy duty maching industry.Traditional universal coupling with spider structure as shown in Figure 1, is provided with radial bearing 1 on the axle journal of cross axle, the axle head of cross axle is provided with thrust-bearing 2, and end cap body 3 inner sides have the round ring boss 4 of location thrust-bearing, as shown in Figure 2.Particularly large-scale, heavy coupling is large owing to carrying, impact is frequent, operating mode is severe for universal coupling with spider, the difficult radial bearing that often can cause of maintenance damages; thrust bearing wearing; cause bearing vibration aggravation, even stop production or cause equipment accident.The oil groove cross-section area on thrust-bearing that above-mentioned situation occurs is little, oil duct is narrow, when flowing to radial bearing lubricant housings, cross by the oil groove of lubricant oil on thrust-bearing oil not smooth, causing under radial bearing and thrust-bearing working state lubricated insufficiently, easily there is heating, stuck situation of even burning in coupling.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide the end cap with Oil Guide function for universal coupling with spider that a kind of reasonable in design is ingenious, using effect is good.
For achieving the above object, the utility model adopts following technological scheme:
The end cap with Oil Guide function for a kind of universal coupling with spider, inside its end cap body, center is provided with for locating the round ring boss of thrust-bearing, in end cap body inner side, along round ring boss circumferencial direction, be radial some the oil grooves that are evenly distributed with, on round ring boss outer wall, offer and some the oil grooves corresponding guiding gutter communicating one by one, end cap body inner side is provided with a circular groove, the slightly larger in diameter of circular groove is in the diameter of thrust-bearing, and some oil grooves communicate with circular groove.
The end cap with Oil Guide function for described universal coupling with spider, the oil groove quantity that its end cap body inner side arranges is 6~8.
The end cap with Oil Guide function for described universal coupling with spider, the oil groove width that its end cap body inner side arranges is 5~10mm, the degree of depth is 2~4mm.
The end cap with Oil Guide function for described universal coupling with spider, the diameter of its circular groove is greater than the diameter 2~5mm of thrust-bearing.
The end cap with Oil Guide function for described universal coupling with spider, its end cap body arranged outside has cylindric or round table-like projection.
Owing to adopting technological scheme as above, the utlity model has following superiority:
The end cap with Oil Guide function for this universal coupling with spider, its reasonable in design is ingenious, by end cap body interior structure is improved, in end cap body inner side, along round ring boss circumferencial direction, be radial some the oil grooves that are evenly distributed with, while carrying out centralized oil supply by pump nozzle, make original oil groove on thrust-bearing flow to the lubricant oil of radial bearing lubricant housings, flow through many oil grooves of end cap inner side of major part flow to radial bearing lubricant housings, make sufficient lubrication under radial bearing and thrust-bearing working state, extend radial bearing and thrust-bearing working life, can reduce the oiling time, be convenient to safeguard, extend Coupling Life, improve coupling working efficiency.

Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 3, the end cap with Oil Guide function for this universal coupling with spider, its end cap body 3 centers, inner side are provided with for locating the round ring boss 4 of thrust-bearing, in end cap body inner side, along round ring boss circumferencial direction, be radial some the oil grooves 5 that are evenly distributed with, on round ring boss outer wall, offer and some oil grooves guiding gutter 6 one to one, end cap body inner side is provided with a circular groove 7, the slightly larger in diameter of circular groove is in the diameter of thrust-bearing, some oil groove one end communicates with corresponding guiding gutter 6, and the other end communicates with circular groove.
The oil groove quantity that above-mentioned end cap body inner side arranges is 6~8.
The oil groove width that above-mentioned end cap body inner side arranges is 5~10mm, and the degree of depth is 2~4mm.
The diameter of above-mentioned circular groove is greater than the diameter 2~5mm of thrust-bearing, makes the lubricant oil in oil groove flow to radial bearing through circular groove, and can not be subject to stopping of thrust-bearing.
The oil groove of lubricant oil fraction on thrust-bearing flows to radial bearing lubricant housings, and most of guiding gutter 6 on round ring boss 4 flows in many oil grooves of end cap inner side, then flows in circular groove 7, by circular groove, flows to radial bearing lubricant housings.
As shown in Figure 4, the end cap with Oil Guide function for described universal coupling with spider, its end cap body arranged outside has cylindric or round table-like projection, can effectively utilize end cap body interior space, improve end cap body integral rigidity, improve the life cycle of product.
