Abstract
The utility model discloses a shaft sleeve of a main shaft of a double-suction pump, which comprises a shaft sleeve body, wherein the shaft sleeve body is in a stepped shaft shape, a stepped shaft is provided with a through hole, the inner wall and the outer wall at both ends of the shaft sleeve body are respectively provided with an inner chamfer and an outer chamfer, the inner wall of the through hole is provided with an axial key groove, an annular U-shaped groove is arranged at the left side of the inner wall of the through hole of the shaft sleeve body, an annular groove is arranged at the right side of the inner wall of the through hole, and the annular groove is communicated with the annular U-shaped groove. The shaft sleeve body is made of 2Cr13, and the annular U-shaped groove is deeper than the annular groove and is narrower than the annular groove. The shaft sleeve has a simple structure and is convenient to manufacture, the lubrication time and the lubrication efficiency are greatly improved, and the service life of the main shaft is prolonged.
Description
Technical field:
The utility model relates to the double suction pump field, specifically is a kind of double suction pump main shaft sleeve.
Background technique:
Axle sleeve is lower at some rotating speeds, the place that radial load is higher and have relatively high expectations in the gap (as camshaft) is used for substituting rolling bearing (also a kind of at last sliding bearing of axle sleeve in fact), material requirements hardness is low and wear-resisting, aperture grinds scraping in the axle sleeve, can reach higher quality of fit, the oil groove of lubricant oil must be arranged on the inwall of axle sleeve, axle sleeve lubricated extremely important, dry grinding, axle and axle sleeve will soon be scrapped.
Common axle sleeve is scraping axle sleeve inner hole wall when mounted, can stay many small ruts like this, perhaps be exactly processing during axle sleeve long annular recess of hole boring within it strengthen lubricated.Axle sleeve generally plays the sliding bearing effect.For the wall thickness of economical with materials according to the thrust load design axle sleeve of bearing needs.The new shape novel structure of this practicality, easily manufactured, long annular recess and bigger U-groove bevel of groove depth of processing communicates on the inwall of axle, with the oil pocket that can seal after axle cooperates, can strengthen the lubrication time of axle and bearing so effectively, prolong the working life of axle and bearing.
The model utility content:
The purpose of this utility model provides a kind of double suction pump main shaft sleeve, and is simple and practical, solves the traditional lubricating system between axle and the bearing effectively, and lubrication time and lubricating efficiency all have greatly improved.
The technical solution of the utility model is as follows:
The double suction pump main shaft sleeve, comprise the axle sleeve body, described axle sleeve body is the multidiameter shaft shape, multidiameter shaft is provided with through hole, chamfering and outer chamfering in axle sleeve body two ends inside and outside wall is respectively equipped with, the through-hole wall axial keyway is characterized in that: the through-hole wall left side of described axle sleeve body is provided with the ring-type U-groove bevel, through-hole wall right side annular recess, described annular recess communicates with the ring-type U-groove bevel.
Described double suction pump main shaft sleeve is characterized in that: it is 2Cr13 that described axle sleeve body adopts material, and described ring-type U-groove bevel groove depth is greater than annular recess, and groove width is less than annular recess.
The utility model has the advantages that:
The utlity model has simple in structurely, easily manufactured, lubrication time and lubricating efficiency promote greatly, have prolonged the working life of main shaft.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The double suction pump main shaft sleeve, comprise axle sleeve body 1, axle sleeve body 1 is the multidiameter shaft shape, and multidiameter shaft is provided with through hole 2, chamfering 3 and outer chamfering 4 in axle sleeve body 1 two ends inside and outside wall is respectively equipped with, through hole 2 inwall axial keyways 5, the through hole 2 inwalls left side of axle sleeve body 1 is provided with ring-type U-groove bevel 6, through hole 1 inwall right side annular recess 7, and annular recess 7 communicates with ring-type U-groove bevel 6, it is 2Cr13 that axle sleeve body 1 adopts material, and ring-type U-groove bevel 6 groove depths are greater than annular recess 7.
Claims (2)
