Abstract
The utility model relates to a triplex row rolling integral shaft bearing used for automobile engine water pump, comprising an outer ring, an intra-connected shaft and a sealing ring. The bearing is characterized in that the two ends between the outer ring and the intra-connected shaft are provided with rollers, and the middle part is provided with a steel ball. The internal side of the outer ring and the intra-connected shaft are both provided with the roller track corresponding to the rollers. The utility model has the advantages that the rollers are installed at both ends of the water pump integral shaft bearing, and the steel ball is installed in the middle, with the result that stressed points are distributed more reasonably, ensuring that the carrying capacity and fatigue life of the integral shaft bearing are both greatly improved.
Description
Technical field
The utility model relates to a kind of motor car engine water pump bearing, particularly a kind of three lines rolling element bearing for car engine water pump.
Background technique
The used water pump shaft connecting bearings inside of motor car engine water pump is biserial rolling element (see figure 1) at present: an end is a ball, and the other end is a cylindrical roller, or the biserial ball.The advantage of this class formation is that the processing of bearing is more convenient, but also exist following a lot of drawback: because the motor car engine water pump is higher with the shaft connecting bearing rotating speed, bearing load is bigger, particularly the heavy-duty car engine water pump is bigger with the load ratio that shaft connecting bearing bore, the motor car engine water pump supporting with main frame reaches more than 100,000 kilometers with the shaft connecting bearing life requirements, and life requirements is relatively stricter.General heavy-duty car engine water pump is difficult to satisfy 100,000 kilometers requirement with the life-span of shaft connecting bearing, the motor car engine water pump with shaft connecting bearing when work water pump impeller can feed water pump the mandrel power of both direction axially and radially, and the belt belt wheel acts on the radial pull of mandrel, this moment, the steel ball and the load that roller is subjected to of water pump shaft connecting bearings were very big, roller is stronger than the bearing capacity of steel ball, so such water pump shaft connecting bearings generally can produce fatigue failure at the steel ball end, thereby causes a whole set of water pump shaft connecting bearings fatigue failure.The bulk life time of the auto pump shaft connecting bearing of two row rolling elements depends on the endurance life-span of steel ball, thus shorter following fatigue life in the heavy load situation, can not satisfy life requirements.
Summary of the invention
The purpose of this utility model is that the used water pump shaft connecting bearings inside of solution motor car engine water pump of the prior art is the existing the problems referred to above of biserial rolling element, and a kind of three lines rolling element bearing for car engine water pump that overcomes above-mentioned shortcoming is provided.The utility model design vehicle engine water pump is with three row rolling element shaft connecting bearings, comprise outer ring, interior connecting shaft, seal ring, it is characterized in that: the two ends between outer ring and interior connecting shaft are provided with roller, be provided with steel ball in the centre, in the inboard, outer ring reaches, all have and the corresponding raceway of steel ball on the connecting shaft.The utility model has the advantages that at the two ends of water pump shaft connecting bearings roller is installed, the middle steel ball of installing, the force bearing point that more reasonably distributes significantly improves the bearing capacity of shaft connecting bearing and fatigue life.
Description of drawings
Accompanying drawing 1 is existing motor car engine water pump shaft connecting bearing structural representation,
Accompanying drawing 2 structural representations of the present utility model,
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise outer ring 1, interior connecting shaft 2, seal ring 3 among Fig. 2, it is characterized in that: the two ends between outer ring 1 and interior connecting shaft 2 are provided with roller 4, are provided with steel ball 5 in the centre, all have and steel ball 5 corresponding raceways 6 on the connecting shaft 2 in 1 inboard the reaching of outer ring.Wherein be positioned at the roller 4 at two ends so that bear heavy load, middle steel ball 5 plays the positioning action of the internal connecting shaft 2 of restrictive axial play.
The utility model increase by a row rolling element, and changed the stressed distribution of original structure, the bearing capacity and the fatigue life of having improved water pump shaft connecting bearings, solved the problem that existing water pump shaft connecting bearings bearing capacity is low and fatigue life is short.
