Background technique
At present, the shaft connecting bearing inside used of automobile engine water pump is biserial rolling element (as shown in Figure 1): an end steel ball, the other end are cylindrical roller; Perhaps Double-row ball.The shaft connecting bearing advantage of this class formation is that the processing of bearing is more convenient.But because automobile engine water pump is higher with the shaft connecting bearing rotating speed, bearing load is larger, particularly the engine of heavy-duty car water pump is larger with the load ratio that shaft connecting bearing bears, the automobile engine water pump supporting with main frame reaches more than 100,000 kilometers with the shaft connecting bearing life requirements, and life requirements is stricter; Existing engine of heavy-duty car water pump is difficult to satisfy the requirement of 100,000 kilometers with the life-span of shaft connecting bearing.
In practical work process, automobile engine water pump with shaft connecting bearing when work water pump impeller can feed water pump mandrel axially and radially the power of both direction and belt belt wheel are very large to the load that the radial pull, particularly roller end of mandrel is subject at this moment.In order to strengthen the bearing capacity of roller, generally can adopt increases roller diameter or roller length, and roller diameter can not be increased by the bearing outside diameter dimension constraint, so generally can increase roller length; But according to the stressing conditions of water pump shaft connecting bearings, roller length is longer, and during work, the roller two ends more easily produce the seesaw phenomenon, cause discontinuity, is easy to cause that bearing temperature rise is large, insufficient lubrication, and last bearing produces fatigue flake in advance.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of engine water pump shaft connecting bearing, adopts the setting of three row rollers, effectively improves bearing capacity and fatigue life.
For achieving the above object, the utility model provides following technological scheme: a kind of engine water pump shaft connecting bearing, include bearing outer ring, and be equipped with the interior connecting shaft coaxial with bearing outer ring in bearing outer ring; Between bearing outer ring and interior connecting shaft, the interval forms installation cavity, be provided with roller assembly in described installation cavity, be provided with the black box with the installation cavity sealing at installation cavity two end part, described roller assembly comprises steel ball, steel ball retainer, cylindrical roller and cylindrical roller retainer, steel ball is assemblied in installation cavity by steel ball retainer, and cylindrical roller is assemblied in installation cavity by cylindrical roller retainer; Described steel ball and cylindrical roller arrange along interior connecting shaft axial distribution, in described installation cavity, an axial end is equipped with a row steel ball by steel ball retainer, be equipped with the raceway corresponding with steel ball on bearing outer ring inboard and interior connecting shaft, in installation cavity, the axial the other end is equipped with by cylindrical roller retainer and is two line column rollers that axial distribution arranges;
Described cylindrical roller retainer is provided with the two row pocket holes that are that axial distribution arranges, being equipped with cylindrical roller in two row pocket holes consists of two row and is the cylindrical roller that axial distribution arranges, be extended with positioning convex on the collar wall of described cylindrical roller retainer, described positioning convex is located at cylindrical roller retainer with respect on the other end of steel ball one end, described bearing outer ring madial wall is provided with the positioning groove adaptive with positioning convex, and described positioning convex embeds in positioning groove.
By adopting technique scheme, an end is installed two line column rollers and is improved bearing capacity, and the other end is installed the effect that steel ball plays location and carrying; By increasing by a row rolling element, changed the distribution of force of original structure, improved bearing capacity and the fatigue life of water pump shaft connecting bearings, solve existing water pump shaft connecting bearings bearing capacity and hang down and short problem fatigue life; Cylindrical roller retainer forms reliable location and installation by the positioning groove on positioning convex embedded axle bearing outer-ring.
Below in conjunction with accompanying drawing, the utility model is further described.
