Abstract
The utility model discloses a novel double row contact ball bearing for a plunger pump which essentially comprises an outer ring (01), a inner ring (02), a roller (03) and a roller holder (04), adopts an integral inner ring and a separable outer ring, forms point contacts by a plunger and an inside diameter groove, properly matches the plunger and the bearing by using a reasonable oil film, whereby reducing the wears, conveniently assembling and installing, meeting the operating requirement of plunger pump high accuracy.
Description
Technical field:
The utility model relates to design bearing and manufacturing technology field, a kind of novel plunger pump double-row angular contact bal bearing.
Background technique:
At present, the plunger bearing in pump has two half inner ring double-row angular contact bal bearings, hydrostatic bearing, self-lubricating oily bearing etc., and these bearing structures are complicated, and assembling is also difficult, can not satisfy the usage requirement of plunger pump highi degree of accuracy.As two half inner ring double-row angular contact bal bearings, owing to use axis and inner ring interference fit, there is fretting wear, cause the longevity of bearing and axle.
Summary of the invention:
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of novel plunger pump double-row angular contact bal bearing, it adopts the integrated type inner ring, form a little with the internal diameter groove by plunger simultaneously and contact, utilize rational oil film to form the suitable cooperation of plunger and bearing, reduce wearing and tearing, assembled easy for installationly, satisfied the usage requirement of plunger pump highi degree of accuracy.
For achieving the above object, the utility model adopts following technological scheme:
Described novel plunger pump double-row angular contact bal bearing, it mainly contains outer ring, inner ring, roller and roller cage formation, and its inner ring is an overall structure, is processed with groove on the internal diameter of inner ring; Its outer ring is a separable type structure radially.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
Plunger pump double-row angular contact bal bearing of the present utility model, it utilizes plunger and internal diameter groove to form point and contacts, form the suitable cooperation that rational oil film makes plunger and bearing, wearing and tearing have been reduced, thereby also prolonged the working life of bearing, be fit to the particular device demand structure, assembled easy for installation, maintain easily, satisfy specialized requirement.
Description of drawings:
Fig. 1 is a novel plunger pump double-row angular contact bal bearing structural representation;
Number in the figure: 01-outer ring; The 02-inner ring; The 03-roller; The 04-roller cage; The 05-plunger; The 06-plunger pump.
Embodiment:
As shown in Figure 1, the described novel plunger pump double-row angular contact bal bearing that this is novel, it mainly contains outer ring (01), inner ring (02), roller (03) and roller cage (04) and constitutes.Its inner ring (02) is an overall structure, is processed with groove on the internal diameter of inner ring (02); Its outer ring (01) is a separable type structure radially.
During assembling, earlier inner ring (02) is kept flat, earlier a roller cage (04) is put into inner ring (02) outer and; Again one group of roller (03) is also contacted with inner ring (02) inner ring from this part roller cage (04) of radially packing into; Then another roller cage (04) is used with quadrat method and packed into and contact,, guarantee that steel ball does not drop out and rotates flexibly more respectively with even cutter seal locking steel ball around the ball pocket hole on the outer diametric plane of two roller cages (04) with another raceway; At last two outer rings (01) is loaded onto respectively with roller (03) and contacted, promptly finish assembling, inner ring during use (02) cooperates with the plunger (05) of plunger pump (06) lining, forms rational oil film, has satisfied mechanism's requirement.
