Abstract
The utility model relates to a single-row full complement cylindrical roller bearing of no outer lane and holder, including inner circle and cylindrical roller, cylindrical roller inlays in the inner circle outer wall, and the cylindrical roller overcoat is equipped with and is used for preventing the outside sleeve that deviates from of each cylindrical roller from the inner circle, and cylindrical roller top and bottom pressure equipment have and are used for preventing the check ring of cylindrical roller axial displacement, and separate through the packing ring between check ring and the cylindrical roller terminal surface. Compared with the design with the outer ring and the retainer, the design without the outer ring and the retainer of the utility model has smaller occupied space and compact structure, and reduces the weight of the bearing; the radial bearing capacity of the bearing is greatly improved by adopting the full-complement cylindrical roller design; the utility model is used for in the planetary gear case, the retaining ring at both ends is installed in the draw-in groove of planetary gear axle to restrict cylindrical roller's axial displacement jointly with the inner circle.
Description
The technical field is as follows:
the utility model relates to a bearing technical field especially relates to a single-row full complement cylindrical roller bearing of no outer lane and holder, mainly is applied to planetary gear box's planetary gear epaxial.
Background art:
the single-row full-complement cylindrical roller bearing on the existing planet gear shaft generally comprises an outer ring, an inner ring, a retainer and cylindrical rollers, wherein the outer ring is generally provided with a flange to limit the axial displacement of the cylindrical rollers. The single-row full-complement cylindrical roller bearing has the advantages of large integral volume, large occupied space and heavy weight.
The utility model has the following contents:
to the not enough among the prior art, the utility model provides a simple structure is compact, light in weight, can the radial bearing capacity's of greatly increased bearing no outer lane and the single row full complement cylindrical roller bearing of holder.
The utility model discloses a realize through following technical scheme:
the utility model provides a single-row full complement cylindrical roller bearing of no outer lane and holder, including inner circle and cylindrical roller, cylindrical roller inlays in the inner circle outer wall, the cylindrical roller overcoat is equipped with and is used for preventing the outside sleeve of deviating from of each cylindrical roller follow inner circle, and cylindrical roller top and bottom pressure equipment have and are used for preventing the check ring of cylindrical roller axial displacement, and separate through the packing ring between check ring and the cylindrical roller terminal surface.
In order to limit the cylindrical roller axially, the outer wall of the inner ring is provided with an annular caulking groove in which the cylindrical roller can be partially embedded; further, the stop ring and the gasket are pressed on the outer side of the top end or the bottom end of the cylindrical roller; the axial displacement of the cylindrical roller is limited by the mutual matching of the inner ring, the stop ring and the washer.
In order to facilitate the assembly of the stop ring, which has a certain deformability, the stop ring is provided with a notch.
Preferably, the sleeve is a plastic sleeve.
The beneficial effects of the utility model are that:
(1) the plastic sleeve installed on the bearing can be extruded at the installation position of a customer, is not used as a rotating part, and is only used as a bearing to prevent the cylindrical roller from scattering in the transportation process after the bearing is installed;
(2) compared with the design with the outer ring and the retainer, the design without the outer ring and the retainer occupies smaller space, is suitable for compact structural design, and reduces the weight of the bearing;
(3) the design of full-complement cylindrical rollers greatly increases the radial bearing capacity of the bearing;
(4) the structure is usually used in a planetary gearbox, and the stop rings at two ends are arranged in clamping grooves of a planetary gear shaft, so that the stop rings and the inner ring together limit the axial displacement of the cylindrical roller;
(5) the gasket of certain width makes cylindrical roller rotatory more steady on the both sides pad of cylindrical roller, and the gasket material hardness is close with the rolling element, makes the more wear-resisting of bearing like this.
Description of the drawings:
fig. 1 is a schematic perspective view of a single-row full complement cylindrical roller bearing without an outer ring and a retainer according to the present invention;
