Abstract
The utility model discloses a needle bearing for a gear shifting box. The needle bearing comprises a needle roller, a retainer and an outer cycle; the retainer is mounted in the outer ring, and the needle roller is mounted in a roller path of the retainer; a gasket ring is arranged on the end surfaces of the retainer and the outer ring; the gasket ring is in clearance fit with a transmission shaft of the gear shifting box, and the gasket ring can axially seal the internal diameter of the needle bearing; the outer edge of the gasket ring extends downwards to form a flange, the flange is matched with the groove in the outer ring, and the external diameter of the flange is larger than that of the outer ring, so that the external diameter of the needle bearing can be axially sealed by the flange. The needle bearing for the gear shifting box requires the only one gasket ring, and the gasket ring is mounted on the end surfaces of the retainer and the outer ring, so that the mounting is simple and the cost is low.
Description
Technical field
The utility model relates to a kind of needle bearing, is specifically related to a kind of gearbox needle bearing.
Background technique
Gearbox is nibbled mutually by two gears and is rotated work.Gearbox mainly comprises needle roller, retainer, outer ring with needle bearing, and seal ring one and seal ring two; Retainer is installed in the outer ring, and needle roller is installed in the raceway on the retainer.Be installed on the transmission shaft of gearbox when needle bearing after, not only to seal ring one be installed at axle, carry out axial seal with the internal diameter to needle bearing, and also to a seal ring two be installed in the outer ring and carry out axial seal with the external diameter to needle bearing, as seen its installation is cumbersome, and because the material of two seal rings needs is many, cause its cost compare high.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of gearbox needle bearing, and it can not only be simultaneously carries out axial seal to the internal-and external diameter of described needle bearing, and install simple, cost is low.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of gearbox needle bearing comprises needle roller, retainer, and the outer ring, and described retainer is installed in the described outer ring, and described needle roller is installed in the raceway on the described retainer; One end face of described retainer and described outer ring is provided with a seal ring, the transmission shaft Spielpassung of described seal ring and described gearbox; Downward formation one flange of the outward edge of described seal ring, described flange matches with groove on the described outer ring, and the external diameter of described flange is greater than the external diameter of described outer ring.
Preferably, described retainer is made by nylon.
Preferably, described seal ring and described retainer Spielpassung.
Pass through technique scheme, a kind of gearbox needle bearing that the utility model provides, because the end face in described retainer and described outer ring is provided with a seal ring, the transmission shaft Spielpassung of described seal ring and described gearbox is therefore described seal ring can carry out axial seal to the internal diameter of described needle bearing; And because described flange matches with groove on the described outer ring and the external diameter of described flange greater than the external diameter of described outer ring, therefore flange can carry out axial seal to the external diameter of described needle bearing; In addition, because this gearbox only needs a described seal ring with needle bearing, and described seal ring is installed on the end face of described retainer and described outer ring, thus its install simply, cost is low.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.
Fig. 1 is the structural representation that the disclosed a kind of gearbox of the utility model embodiment is used needle bearing.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
With reference to shown in Figure 1, a kind of gearbox needle bearing provided by the utility model, it comprises needle roller 3, retainer 2, and outer ring 1, and described retainer 2 is installed in the described outer ring 1, and described needle roller 3 is installed in the raceway on the described retainer 2; Described retainer 2 is provided with a seal ring 4, the transmission shaft Spielpassung of described seal ring 4 and described gearbox with an end face of described outer ring 1; Downward formation one flange 41 of the outward edge of described seal ring 4, described flange 41 matches with groove on the described outer ring 1, and the external diameter of described flange 41 is greater than the external diameter of described outer ring 1.Described retainer 2 is made described seal ring 4 and described retainer 2 Spielpassung by nylon.
A kind of gearbox needle bearing that the utility model provides, because the end face in described retainer 2 and described outer ring 1 is provided with a seal ring 4, the transmission shaft Spielpassung of described seal ring 4 and described gearbox is therefore described seal ring 4 can carry out axial seal to the internal diameter of described needle roller 3 bearings; And because described flange 41 matches with groove on the described outer ring 1, and the external diameter of described flange 41 is greater than the external diameter of described outer ring 1, therefore described flange 41 can carry out axial seal to the external diameter of described needle roller 3 bearings; In addition, because this gearbox only needs a described seal ring 4 with needle roller 3 bearings, and described seal ring 4 is installed on the end face of described retainer 2 and described outer ring 1, therefore that it is installed is simple, cost is low.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
1. gearbox needle bearing, comprise needle roller, retainer, and outer ring, described retainer is installed in the described outer ring, described needle roller is installed in the raceway on the described retainer, it is characterized in that, an end face of described retainer and described outer ring is provided with a seal ring, the transmission shaft Spielpassung of described seal ring and described gearbox; Downward formation one flange of the outward edge of described seal ring, described flange matches with groove on the described outer ring, and the external diameter of described flange is greater than the external diameter of described outer ring.
