Abstract
The utility model discloses a one end sealing opening type punched outer ring rolling needle bearing. The aim is to provide a punched outer ring rolling needle bearing having the advantages of simple structure, little frictional resistance and high rotational efficiency. The utility model comprises a punched outer ring and a rolling needle, wherein the center of the end surface of the punched outer ring is punched with a spherical lug boss which is bulged towards the inner end. The contact of the rolling needle bearing and the shaft end surface is only the center of a shaft. The resistance moment in transmission can be reduced, the mechanical work efficiency is improved and the power consumption is reduced.
Description
Technical field
The utility model relates to needle bearing, relates in particular to an a kind of end closure type drawn cup needle roller bearing.
Background technique
Needle bearing is a kind of part commonly used in the mechanical rotation.In order to make the part axial location that is installed on the needle bearing, make at the cycle surface of needle bearing and seal, wear with restrictive axial, and what generally adopt is to make flat barrel-shaped outer ring with the method for punching press pull and stretch.In use the outer ring generally is fixed on bearing support or the casing, the interior edge face of drawn cup, block the end face of axle, play axially locating, this structure is because whole axial end contacts friction with the interior edge face of drawn cup, the friction circle radius is big, and the frictional resistance square is big, can reduce mechanical rotation efficient.
The content of model utility
The utility model has overcome the shortcoming that exists in the prior art, provides a kind of frictional resistance little, the end closure type drawn cup needle roller bearing that rotational efficienty is high.
In order to solve the problems of the technologies described above, the utility model is realized by following scheme: comprise drawn cup, needle roller, be shaped on ball-type boss to inner projection at the end face centre punch of drawn cup.
End closure type drawn cup needle roller bearing according to such scheme is made being a bit at the center of axle with contacting of axial end, can reduce the resisting moment in the transmission, improves machine work efficient, reduces power consumption.The enforcement of this technology needs only to add on the upper and lower mould of drawn cup makes corresponding boss and pit, and processing technology does not originally change.
Description of drawings
Fig. 1 is the structural representation of an end closure type drawn cup needle roller bearing;
Fig. 2 is the structural representation that retainer one end closure type drawn cup needle roller bearing is arranged.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
An end closure type drawn cup needle roller bearing comprises arranging in the drawn cup 1, drawn cup 1 and is placed with needle roller 2, by retainer 3 they is separated between each needle roller 2 in the drawings, is shaped on ball-type boss 4 to inner projection at the end face centre punch of drawn cup.When an end closure type drawn cup needle roller bearing installed on the axle 5, ball-type boss 4 can reduce the resisting moment in the transmission like this being any at the center of axle 5 with contacting of axle 5 end faces, improves machinery driving efficiency.
Claims (2)
1, an a kind of end closure type drawn cup needle roller bearing comprises the outer ring of punching press, arranges in drawn cup and be placed with needle roller, it is characterized in that end face centre punch at drawn cup is shaped on the ball-type boss to inner projection.
2, an end closure type drawn cup needle roller bearing according to claim 1 is characterized in that being equipped with between each needle roller the retainer that each needle roller is separated.
