Abstract
The utility model relates to a belt pulley and bearing integrated automobile water pump and belongs to the filed of pumps. The automobile water pump comprises a water pump body and a water pump shaft. A water seal and an impeller are mounted at the lower end of the water pump body, and a 'belt pulley and bearing combination part' is arranged at the upper end of the water pump body. According to the automobile water pump, a bearing outer ring is rigidly integrated with a connection plate, so that torque is transmitted to the water pump shaft through the bearing outer ring and then to the impeller. Radial force generated by belt tension is born by the bearing and is transmitted to the water pump body through a bearing inner ring, and the water pump shaft does not bear the radial force and bending moment generated by the belt tension, so the load born by the water pump is reduced by more than 70%, and the reliability of the water pump shaft is greatly improved.
Description
Technical field
The utility model relates to a kind of water pump, belongs to pump class field, the auto pump of especially a kind of belt pulley and bearing disjunctor.
Background technique
Traditional auto pump, its belt pulley and bearing are two bodies, its transmission of power direction is: moment of torsion takes turns to water pump spindle by belt, then to impeller.Water pump spindle bears radial force, the moment of flexure that belt tension produces, and through bearing outer ring, passes to water pump body supporting.Now water pump spindle has born a large amount of radial forces and moment of flexure, in order to guarantee that its normal operation is generally overstriking water pump spindle, thereby cause water pump body and water pump spindle high material consumption, and water pump spindle easily ruptures at work.Make poor reliability, the water pump spindle of water pump short working life.
Model utility content
The purpose of this utility model is the deficiency existing in background technique for overcoming, and proposes that a kind of water pump volume is little, reliability is strong, consumption of materials is few and the auto pump of the belt pulley of water pump spindle long service life and bearing disjunctor.
For achieving the above object, the utility model adopts following scheme:
An auto pump for belt pulley and bearing disjunctor, comprises water pump body and water pump spindle, and water seal and impeller are equipped with in water pump body lower end, and belt pulley bearing assembly parts is equipped with in water pump body upper end.
In the auto pump of above-mentioned belt pulley and bearing disjunctor, belt pulley bearing assembly parts comprises: connecting plate, bearing outer ring and bearing inner race, bearing outer ring and inner ring are a complete double-row angular contact bal bearing, bearing outer ring and connecting plate are rigidly connected as belt pulley, between belt pulley and water pump spindle external diameter, interference fit connects, and between bearing inner race and water pump body, interference fit supports.
In the auto pump of above-mentioned belt pulley and bearing disjunctor, connecting plate and bearing outer ring are rigidly connected by the mode of riveted or welding.
The present invention's beneficial effect is compared to existing technology: this practicality is by being rigidly connected bearing outer ring and connecting plate to be integrated, make moment of torsion by bearing outer ring to water pump spindle, then to impeller.Bearing bears the radial force that belt tension produces, and via bearing inner race, passes to water pump body.Water pump spindle does not bear radial force and the moment of flexure that belt tension produces.Thereby the load reduction that water pump spindle bears is more than 70%, and the reliability of water pump spindle is greatly improved.
Accompanying drawing explanation
Fig. 1 is the sectional view of the auto pump of the utility model belt pulley and bearing disjunctor.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment one:
A kind of belt pulley as shown in Figure 1 and the auto pump of bearing disjunctor, comprise water pump body 1 and water pump spindle 3, and water seal 4 and impeller 5 are equipped with in water pump body lower end, and belt pulley bearing assembly parts 2 is equipped with in water pump body upper end.Belt pulley bearing assembly parts 2 comprises: connecting plate 6, bearing outer ring 7 and bearing inner race 8 etc.In work, by by being rigidly connected of bearing outer ring 7 and connecting plate 6, make moment of torsion by bearing outer ring 7 to water pump spindle 3, then to impeller 5, make water pump body 1 directly stressed and then reduce its working life of stressed assurance of water pump spindle 3.
In above-mentioned, in order to guarantee the stable of its connection, connecting plate 6 and bearing outer ring 7 are rigidly connected by the mode of riveted.
Embodiment two
In order to make its structure more stable, connecting plate 6 and bearing outer ring 7 are rigidly connected by the mode of welding, because other technologies feature does not change, so locate just not repeat.
The foregoing is only better embodiment of the present utility model, not take the present embodiment as restriction, all any modifications of making within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all can being included in protection domain of the present utility model.
Claims (3)
