Description
Technical field
The utility model relates to the bearing reducing load friction system, and specifically a kind of four oily rachises are held.
Background technique
Bearing is the requisite vitals of gear-box.In the world, when the rotating speed of axle is greater than 3600RPM, bearing does not allow to use common cylinder bearing.If adopt common cylinder bearing when high speed (rotating speed is greater than 3600RPM), the raising along with running speed increases by its surface friction drag in direct ratioly; Its result, lubricating oil temperature raises, and deterioration of lubricant, causes rupture of oil film, causes axle to contact with watt (bearing), causes bearing wear serious, burns even.
Model utility content
In order to avoid there is larger friction, the exceeding standard of vibration and temperature rise, the purpose of this utility model is to provide a kind of four oily rachises to hold.
The purpose of this utility model is achieved through the following technical solutions:
The internal surface of the bearing support that the oily rachis of the utility model four is held along the circumferential direction has four oil-feed tanks, described bearing support along the circumferential direction has multiple oil inlet hole, each described oil inlet hole is all offered along the radial direction of bearing support, and each described oil-feed tank is all connected with at least one oil inlet hole.
Wherein: the both sides of each described oil-feed tank length direction are equipped with slope angle; Each described slope angle is wedge shape.
Advantage of the present utility model and good effect are:
1. the utility model has offered four oil-feed tanks on bearing support, has four oil-feed positions, such that bearing temperature rise is low, running is stable, oil resistant film lasing capability is strong, bearing capacity is strong.
2. along the sense of rotation of axle, the utility model is all processed with slope angle in each oil-feed tank position, is convenient to lubricant oil and enters in oil-feed tank, can form oil film better, makes lubrication and cooling effect reach best.
Accompanying drawing explanation
Fig. 1 is front sectional view of the present utility model;
A-A sectional view of Fig. 1 when Fig. 2 is single-rotating direction;
Fig. 3 is H-H sectional view of Fig. 1;
A-A sectional view of Fig. 1 when Fig. 4 is dual rotary direction;
Wherein: 1 is bearing support, 2 is oil-feed tank, and 3 is oil inlet hole, and 4 is slope angle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 3, the internal surface of the bearing support 1 that the oily rachis of the utility model four is held along the circumferential direction has four oil-feed tanks 2, bearing support 1 along the circumferential direction has multiple oil inlet hole 3, each oil inlet hole 3 is all offered along the radial direction of bearing support 1, and each oil-feed tank 2 is all connected with at least one oil inlet hole 3; In the present embodiment, each oil-feed tank 2 is all communicated with two oil inlet holes, 3, two oil inlet holes 3 and arranges with the Central Symmetry of oil-feed tank 2.
The both sides of each oil-feed tank 2 length direction are equipped with the slope angle 4 of wedge shape.The present embodiment is the sense of rotation along axle, angle 4 is broken in the wedge shape of the position of each oil-feed tank 2 processing one dark 0.2mm, length (circumferentially) 8mm, lubricant oil is entered in oil-feed tank 2 more swimmingly, forms oil film better, make lubrication and cooling effect reach best.The temperature that the utility model can make four oily rachises hold when normal work reduces by 7 ~ 10 DEG C.
As shown in Figure 2, when axle is single-rotating direction, the angle of four oil-feed tanks 2 along the circumferential direction cloth is respectively 25 °, 115 °, 205 °, 295 ° (along Y-axis).As shown in Figure 4, when axle is dual rotary direction, the angle of four oil-feed tanks 2 along the circumferential direction cloth is respectively 70 ° ,-110 °, 70 °, 110 ° (along Y-axis).
Working principle of the present utility model is:
Bearing is the requisite vitals of gear-box, and bearing is the safety of rotor, smooth operation provides four rigidity and four dampings.The oily rachis of the utility model four is held and belongs to dynamic pressure type, the carrying oil film of four sections of pole books (25mm) can be formed between axle and watt (four oily rachises are held), avoid axle and watt to contact with each other, because of but neat liquid friction, its friction is only the friction between oil reservoir, friction factor is very little, only has 0.001 ~ 0.005.Four oily rachises of the present utility model are held owing to adding three oil film wedges, and stability greatly improves; Again owing to there being four oil-feed positions, bearing temperature also reduces, and is therefore well suited for running up, and its linear velocity can reach 60m/s, and bearings ratio to press can reach 30kg/cm
2.For the equipment requiring clockwise and anticlockwise, it also can well work.
Claims (3)
1. an oily rachis is held, it is characterized in that: the internal surface of the bearing support (1) that this four oily rachis is held along the circumferential direction has four oil-feed tanks (2), described bearing support (1) along the circumferential direction has multiple oil inlet hole (3), each described oil inlet hole (3) is all offered along the radial direction of bearing support (1), and each described oil-feed tank (2) is all connected with at least one oil inlet hole (3).
