The present invention adopts technique scheme, without the need to increasing power and transmission device in addition, greatly can simplify mechanical structure, reducing costs; On disc parameter and casing, the appropriate design of groove shape, lubricates very reliable; The part of system is few, and structure is simple; In product using process, there is the possibility damaged hardly, the reliability of whole machine is promoted greatly.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is structural representation of the present invention;
Fig. 2 be A-A in Fig. 1 to cross-sectional schematic.
Be labeled as in figure:
1, casing, 2, disc, 3, axle, 4, oil outlet tube, 5, union cross, 6, pumping cavity, 7, radially to protrude, 8, casing inward flange.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technological scheme.
Structure of the present invention expressed as shown in Figure 1, Figure 2, for a kind of mechanical lubrication structure, be applied in mechanical transmission mechanism, described mechanical transmission mechanism is provided with casing 1 and axle 3, described casing 1 is provided with casing inward flange 8, and described axle 3 is bearing in the hole of described casing inward flange 8 by rolling bearing.
In order to solve prior art Problems existing and overcome its defect, realize the structure simplifying mechanical transmission, improve the goal of the invention of the effect of lubrication, the technological scheme that the present invention takes is:
As shown in Figure 1 and Figure 2, mechanical lubrication structure provided by the present invention, described axle 3, in the one end be connected with rolling bearing, is provided with disc 2, and described disc 2 is fixedly connected with described axle 3; The cylindrical of described disc 2 is provided with spiral chute;
Described casing inward flange 8 is provided with radial protrusion 7, and protrude on 7 in described radial direction and be provided with pumping cavity 6, described pumping cavity 6 position and described disc 2 axial position adapt, and are communicated with the mounting hole of described rolling bearing; Described casing inward flange 8 is fixed with oil outlet tube 4, and described oil outlet tube 4 passing hole channel is communicated with described pumping cavity 6.
Described oil outlet tube 4 is provided with union cross 5.
Disc 2 screw thread is arranged on axle 3.
Working principle of the present invention is:
Axle 3 rotates and drives disc 2 to rotate, the periphery of disc 2 is processed with spiral chute, when disc 2 rotates, lubricant oil due to centrifugal force effect to circle surrounding throw away, parts of lubricating oil can enter in the pumping cavity 6 shown in figure, mineralization pressure, pressure oil enters union cross 5 through oil outlet tube 4, can be diverted to the position needing lubrication.
Described spiral fluted parameter is: several 3; Pitch 10mm; Groove width 8mm; Groove depth 7mm; The number of turns is 1 circle; Rotation direction is left-handed.
The appropriate design of Spiral groove parameter on disc, lubricates very reliable.
Described pumping cavity 6 is communicated with position with the mounting hole of described rolling bearing, and on the direction of the cross section of described axle 3, being provided with angle is 35 ° ~ 45 ° opening slots.
Pumping cavity 6 is when casting, and angulation is 35 ° ~ 45 ° cone grooves, such as 40 °.Such angle, just in time makes lubricant oil be easy to enter into groove, and makes lubricant oil mineralization pressure, strengthens the conveying capacity of lubricant oil.
Said structure has following characteristics:
1, without the need to additional power and transmission device, greatly can simplify mechanical structure, reduce costs;
2, the appropriate design of groove shape on disc parameter and casing, lubricates very reliable;
3, lubricating system components of the present invention is few, and structure is simple, in product using process, there is the possibility damaged hardly, the reliability of whole machine is promoted greatly.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technological scheme is carried out; or design of the present invention and technological scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
