Abstract
The utility model relates to a bearing, in particular to a double-row cylindrical roller bearing without an outer race. The double-row cylindrical roller bearing without the outer race comprises an inner race, a roller and a retaining frame, wherein roller is arranged on the inner race; double roller paths are provided for the inner race of the double-row cylindrical roller bearing, and the roller is a double-row roller. According to the utility model, the rated static load of the double-row cylindrical roller bearing w is increased by 0.71 times and the dynamic load is increased by 0.41 times because of the double-row roller; the double-row cylindrical roller bearing without the outer race and a single-row cylindrical roller bearing are basically same in processing technologies and both suitable for large-scale production, and the double-row cylindrical roller bearing without the outer race has simpler machining technology of the retaining frame, very easy assembly and higher production efficiency; the double-row cylindrical roller bearing without the outer race and the single-row cylindrical roller bearing can both meet the mechanical parts with requirements for compact radial dimensions; and the double-row cylindrical roller bearing without the outer race is especially suitable for a planetary-type speed reducer and an oil pump.
Description
Technical field
The utility model relates to bearing, particularly a kind of no outer ring Biserial cylindrical roller bearing.
Background technique
No outer ring single row roller bearing has the characteristics of general roller bearing; Higher radially bearing capacity is promptly arranged, also be applicable to the characteristics that high rotational speed, Internal and external cycle can be installed respectively; Simultaneously because no outer ring; Its outer ring is specially adapted to the compact mechanical part of radial dimension, because can be replaced by the support hole.But because the single row roller bearing of no outer ring is not suitable for the king-sized occasion of radial load owing to only a row roller is arranged.
The model utility content
The purpose of the utility model is to provide a kind of no outer ring Biserial cylindrical roller bearing with heavy load characteristic.
The purpose of the utility model realizes through following approach: a kind of no outer ring Biserial cylindrical roller bearing, and it comprises the roller installed on inner ring, the inner ring and the retainer between roller, and the bearing inner race raceway is two raceways, and the roller of adorning is 2 row rollers;
Further, retainer is no rivet integrative-structure.
The utility model does not have the outer ring Biserial cylindrical roller bearing.The utility model does not have outer ring Biserial cylindrical roller bearing and existing no outer ring single row roller bearing (like Fig. 2) structural similarity, but the structure of retainer is different fully.The single row roller bearing retainer of no outer ring is by keeping stand and retainer lid to form jointly; And rely on rivet 9 that they are linked into an integrated entity; And the Biserial cylindrical roller bearing that does not have the outer ring only has one to keep stand, only keeps processing a semi-circle (being commonly called as ball-loading hole) of being convenient to adorn cylindrical roller on the external diameter of stand.It is simple in structure, has saved rivet, and assembling easily.Because two row rollers are arranged, the basic static capacity (BSC) rating of Biserial cylindrical roller bearing (than RN2317E) increases by 0.71 times.Dynamic load then increases by 0.41 times.The Biserial cylindrical roller bearing of no outer ring and single-row processing technology are basic identical, and all applicable to production in enormous quantities, but the retainer mechanical processing technique of biserial is simpler, and assembling is easy to, and manufacturing efficiency is higher.Can both satisfy the compact mechanical part of radial dimension requirement.Be specially adapted on epicyclic type machine and the oil pump.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain:
Fig. 1 is the utility model structural representation;
Fig. 2 is existing roller bearing structural representation;
Among the figure, inner ring 2, roller 4, retainer 6, rivet 9.
Embodiment
As shown in Figure 1, the utility model does not have the outer ring Biserial cylindrical roller bearing, and it comprises on inner ring 2, the inner ring 2 retainer 6 of 4 on the roller 4 installed and roller, and bearing inner race 2 raceways be pair raceways, the roller of adorning 4 be two row rollers; Retainer 6 is no rivet integrative-structure.
Claims (2)
1. no outer ring Biserial cylindrical roller bearing, it comprises that inner ring (2), inner ring (2) go up the roller (4) installed and the retainer (6) between roller (4), it is characterized in that: inner ring (2) raceway is two raceways, the roller of adorning (4) be 2 row rollers.
2. no outer ring as claimed in claim 1 Biserial cylindrical roller bearing is characterized in that: retainer (6) is no rivet integrative-structure.
