Abstract
The utility model relates to a sliding bearing for magnetic force driving pump, consisting of an inner cylinder and an outer cylinder. A spiral groove is arranged on the internal circumference surface on the inner cylinder and a straight groove is arranged on the end face of the inner cylinder. The spiral groove and the straight groove are communicated with each other, and a channel is formed. Therefore, the lubricating oil stored on the bottom of the bump can be transmitted to the end faces of the shaft sleeve and the thrust shaft sleeve which are rubbed with each other through the spiral groove inside the inner cylinder, and a lubricating film is formed. The product wear and broken caused by the lacking of lubrication on the two end faces can be effectively avoided, and the service life of the products can be prolonged.
Description
Technical field: the utility model relates to a kind of magnetic force driving pump, particularly relates to the sliding bearing that a kind of magnetic force driving pump uses.
Background technique: the rotor part of magnetic force driving pump (rotary component that impeller, interior magnet rotor and pump shaft are formed) and stator component adopt axle sleeve to be connected with sliding bearing between (be used for the rotation of support rotor parts, and the pump cover assembly parts that maintains static) usually.Sleeve end thrust bearing and sliding bearing end face respectively each other friction pair rotate mutually.The sliding bearing that the manufacturer of existing many magnetic drive pumps uses, endoporus circumferential surface are smooth surface or drive two straight-line grooves, pump axle sleeve and thrust bearing rotate with rotor in the running; The inner peripheral surface of sleeve outer circle side face, thrust bearing end face and sliding bearing and end face form friction pair, because the lubrication effect between this friction pair is relatively poor, be easy to contact friction each other and surpass into wearing and tearing or cracked, thereby cause the life cycle of sliding bearing short, defectives such as rate of fault height, sometimes also can cause other damages of parts in addition, have a strong impact on the normal operation of pump.
Summary of the invention: the purpose of this utility model will provide a kind of sliding bearing for magnetic force driving pump exactly, and it can overcome the existing defective of above design.The purpose of this utility model is achieved in that a kind of sliding bearing for magnetic force driving pump, is made up of exterior circular column, inner cylinder, it is characterized in that: be provided with the fixedly spiral chute of rotation direction on described inner cylinder inside circumference face; Both ends of the surface at inner cylinder offer straight trough, and the spiral chute on described straight trough and the inner cylinder inside circumference face is interconnected to form a passage.The utility model project organization is simple, can solve the mutual friction mutually of axle sleeve and sliding bearing end face well.Thereby reach the purpose that prolongs life of product.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
1. inner cylinder, 2. spiral chute, 3. straight trough.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
In the drawings, a kind of sliding bearing for magnetic force driving pump is made up of exterior circular column, inner cylinder, it is characterized in that: be provided with the fixedly spiral chute 2 of rotation direction on described inner cylinder 1 inside circumference face; Both ends of the surface at inner cylinder 1 offer straight trough 3, and the spiral chute 2 on described straight trough 3 and the inner cylinder 1 inside circumference face is interconnected to form a passage.During concrete enforcement, the spiral slot of rotation direction and the straight trough that end face is offered are interconnected to form a passage with offering fixedly on the sliding bearing inner peripheral surface.Pump axle sleeve and thrust bearing in the running rotates with rotor, the sleeve outer circle side face, the inner peripheral surface of thrust bearing end face and sliding bearing and end face form the friction pair that has lubricating film by spiral chute, lubricant oil flow into two end faces of rotation mutually by spiral chute, thereby make the sleeve outer circle side face, the inner peripheral surface of thrust bearing end face and sliding bearing and end face form and seemingly connect the angle but not state of contact, be difficult for producing wearing and tearing each other, greatly reduce the rate of fault of pump, prolonged the working life of sliding bearing, can also play simultaneously the effect of balance portion axial force, improve the stability and the reliability of pump operation.
