Abstract
A thrust roller bearing for a vertical lathe includes an outer ring (1), an inner ring (2), a roller (3) and a cage (4); the outer diameter, inner diameter and width of the outer ring are equal to that of the inner ring. Owing to the same structure size of the outer ring and the inner ring, they have the interchangeability. Meanwhile, the outer diameter of the outer ring and the inner ring is the size adaptive to the installation and the inner diameter of the outer ring and the inner ring is the positioning size. A row of rollers are disposed between the radial end faces of the outer ring and the inner ring. The roller is the cylindrical roller machined by a II level logarithmic profile; the space between a row of rollers is limited by a split type cage; a radial end face of the split type cage is a stepladder-like notch which is clamped on two ends of an inner diameter right-angle face of the inner ring; the split type cage includes an excircle end cover and a pocket main body; and the excircle end cover is fixed on the outer diameter of the pocket main body by a screw. The utility model has simple structure and low cost.
Description
Technical field
The utility model belongs to technical field of bearings, specially refers to a kind of vertical lathe cylindrical roller thrust bearing.
Background technique
Cylindrical roller thrust bearing is a kind of bearing commonly used, the external diameter interference fit of the inner ring of this class bearing and join axle usually, and outer ring and the join internal diameter interference fit of bearing support, the external diameter that retainer and rolling element assembly are joined spool by institute is located.
For main equipment such as vertical lathe, its turning axle can not with the bearing inner race interference fit, retainer and rolling element assembly can not rely on the external diameter location of turning axle.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of vertical lathe cylindrical roller thrust bearing, the inner ring of this bearing and the external diameter of outer ring are interference fit with the internal diameter of axle and seat, be processed with positioning spigot at bearing holder end-face, retainer and rolling element assembly can inner circle internal diameter location.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of vertical lathe comprises outer ring, inner ring, roller and split type retainer with cylindrical roller thrust bearing, and feature of the present utility model is:
The external diameter of outer ring and internal diameter and width equal external diameter and the internal diameter and the width of inner ring, configuration one row roller between the radial end face of outer ring and inner ring, spacing between the one row roller is spacing by split type retainer, the stepped draw-in groove of one radial end face of split type retainer, described stepped draw-in groove are stuck in the face two ends, internal diameter right angle of inner ring.
Described vertical lathe cylindrical roller thrust bearing, split type retainer is made of cylindrical end cap and pocket hole body, the cylindrical end cap by screw on the external diameter of pocket hole body.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
1, the utility model is simple in structure, and cost is low.
2, inner ring of the present utility model and outer ring be by its external diameter interference fit, and be easy for installation.
3, split type retainer of the present utility model and the inner circle of roller are accurately located, and be very reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1: 1-outer ring; 2-inner ring; 3-roller; 4-split type retainer.
Embodiment
In conjunction with Fig. 1, vertical lathe of the present utility model comprises outer ring 1, inner ring 2, roller 3 and split type retainer 4 with cylindrical roller thrust bearing.
The external diameter of outer ring 1 and internal diameter and width equal external diameter and the internal diameter and the width of inner ring 2, because outer ring 1 is identical with inner ring 2 physical dimensions, therefore outer ring 1 and inner ring 2 have interchangeability, and the external diameter of outer ring 1 and inner ring 2 is for installing fit dimension simultaneously, and the internal diameter of outer ring 1 and inner ring 2 is a location dimension.
Configuration one row roller 3 between the radial end face of outer ring 1 and inner ring 2, roller 3 adopts the cylindrical roller of II level logarithm shape correction of the flank shape.
Spacing between the one row roller 3 is spacing by split type retainer 4, and the stepped draw-in groove of a radial end face of split type retainer 4, described stepped draw-in groove are stuck in the face two ends, internal diameter right angle of inner ring 2.Split type retainer 4 is made of cylindrical end cap and pocket hole body, the cylindrical end cap by screw on the external diameter of pocket hole body.
Cylindrical roller thrust bearing precision of the present utility model is made as the P5 level, and axially dynamic load rating can reach 1400 kN.
Claims (2)
1. a vertical lathe comprises outer ring (1), inner ring (2), roller (3) and retainer (4) with cylindrical roller thrust bearing, it is characterized in that: the external diameter of outer ring (1) and internal diameter and width equal external diameter and the internal diameter and the width of inner ring (2), configuration one row roller (3) between the radial end face of outer ring (1) and inner ring (2), spacing between the one row roller (3) is spacing by split type retainer (4), the stepped draw-in groove of one radial end face of split type retainer (4), described stepped draw-in groove are stuck in the face two ends, internal diameter right angle of inner ring (2).
2. vertical lathe cylindrical roller thrust bearing according to claim 1, it is characterized in that: split type retainer (4) is made of cylindrical end cap and pocket hole body, the cylindrical end cap by screw on the external diameter of pocket hole body.
