Abstract
The utility model discloses a bearing liner which avoids the faultiness in the matching of current bearing lines with the end caps, which results in grinding of the axillare and burning tile, thus affecting production. The utility model is simple in structure and is convenient to use and can further reduce damage during use and prolong service life. The utility model structurally comprises a liner which matches with the end cap of the bearing, and an oil trough with an opening is arranged on the liner.
Description
Technical field
The utility model relates to a kind of bearing bush body.
Background technique
The main bearing of grinding machine is a sliding bearing, to be applicable to the high speed of equipment, heavy duty.After adding lubricant oil between friction surface, oil is adsorbed on the metal surface, forms oil film as thin as a wafer, that resistivity is extremely strong, is protecting the metal surface, plays the effect that reduces friction between the surface, wearing and tearing.Being in the metal surface under the liquid abrasion state, is the optimum state of equipment operation.Can not well form oil film because fuel feeding is bad when running up between the bearing bush of grinding machine and the end cap, and bearing bush is because installation question, production problem, often occurs grinding watt, quality problems such as tile kilning.Want to solve this difficult problem fully, very big difficulty is arranged.
Summary of the invention
The purpose of this utility model is exactly to cooperate imperfection in order to solve between present bearing bush body and end cap, problems such as influence production occur grinding watt, tile kilning, provide a kind of have simple in structure, easy to use, in use reduce to damage the bearing bush body of advantage such as increase the service life better.
For achieving the above object, the utility model adopts following technological scheme:
A kind of bearing bush body, it comprises the lining body that cooperates with bearing (ball) cover, described lining body is provided with the oil groove of band opening.
Described oil groove is parabola shaped, and its tip is subjected to centre of force portion to leave the gap with the lining body, and the oil groove opening is arranged on end cap screw-in place.
Described oil groove and end cap screw in the radian of homonymy greater than opposite side.
The utility model can make lubricant oil oil before bearing operation enter the heart portion that serves as a contrast body by gravity own, plays the effect of fuel feeding in advance.
The beneficial effects of the utility model are: it is simple in structure, and is easy to use, is the improvement for grinding machine series products bearing bush structure, it is in use reduced better damage, and increases the service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A zoomed-in view of Fig. 1 oil groove.Wherein, 1. serve as a contrast body, 2. oil groove.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, Fig. 2, be provided with oil groove 2 on lining body 1, the arc shape of oil groove 2 forms y=ax according to parabolical coordinate
2+ bx+c, but also very not strict, total target is the comparison slyness.Oil groove 2 must have opening, and opening will be at end cap screw-in place, better oil is brought into lining body 1.The tip of oil groove 2 can not reach the stressed heart portion of lining body 1, can hold up up to a hundred tons the equipment of weighing with the high pressure oil that guarantees equipment entry into service front center portion, can not rush down pressure.The tip of oil groove 1 is broad, can large-arealy be involved in lining body inside with the lubricant oil that guarantees to enter from here, forms good oil film.Oil groove 1 section as shown in Figure 2, its degree of depth and width will make oil can be under the gravity of self flow into more smoothly, the about 7mm of the degree of depth, the about 15mm of radius, too little difficult inflow causes the damage that serves as a contrast body easily too greatly.Can be suitably smaller in the oil groove section with the radian of end cap screw-in homonymy, rounding off, the opposite side radian can some be beneficial to form oil film greatly.
Claims (3)
1. bearing bush body, it comprises the lining body that cooperates with bearing (ball) cover, it is characterized in that: described lining body is provided with the oil groove of band opening.
2. bearing bush body according to claim 1 is characterized in that: described oil groove is parabola shaped, and its tip is subjected to centre of force portion to leave the gap with the lining body, and the oil groove opening is arranged on end cap screw-in place.
