4 points contact between steel ball and raceway groove, are easier to damage raceway groove, cause revolving support damage failure.
Utility model content
In order to solve the above problems, the utility model proposes a kind of L-type single-row ball type slewing bearing of raceway groove zero air void,
It is ingenious in design, zero air void between pivoting support steel ball and raceway groove, solve raceway groove damage problem well.
A kind of L-type single-row ball type slewing bearing of raceway groove zero air void, it includes outer ring, inner ring, steel ball, institute outer ring, inner ring
Section be L-type, raceway groove is provided between outer ring and inner ring；The steel ball rolls in channels, between steel ball be provided with net type every
From block, the outer ring is connected as a single entity with inner ring by steel ball, outer at the outer ring inner ring face of plane and below inner ring on inner ring
Annular groove is provided with the outer ring lower plane in portion, sealing ring is installed in annular groove；The outer ring side is provided with priming cup, positioned at raceway groove
Outside, both sides are respectively equipped with fixing threaded hole to priming cup up and down, and opposite side is provided with plunger, and plunger at one end is cambered surface, and cambered surface forms rolling
One section of road, the other end are provided with positioning hole, run through outer ring, plunger is by circular hole finger setting on outer ring；The inner ring is provided with
Two fixing threaded holes.
The cross sectional shape of the raceway groove is circular arc, and the diameter of circular arc is identical with the diameter of steel ball.
The priming cup is through type forced filling oil cup.
Further, the scale error being likely to occur in process is avoided, causing the diameter of channels cross-section circular arc may omit
More than steel ball size, from the priming cup to lubricating oil is injected between raceway groove and steel ball, lubricating oil film is formed between raceway groove and steel ball,
Ensure zero air void between steel ball and raceway groove.
The utility model has the advantages that it is ingenious in design, the channel structure of pivoting support is improved, four used in the past point connect
Ball channel structure is touched, is contacted between steel ball and raceway groove for 4 points, steel ball and raceway groove contact surface are small so that structure raceway groove 2-5
Failure easy to wear；The utility model uses the L-type single-row ball type channel structure of raceway groove zero air void, the diameter and steel ball of raceway groove circular arc
Diameter, steel ball contacts with the channel wire way of contact, zero air void between steel ball and raceway groove, increases the contact surface of steel ball and raceway groove
Product so that the wearability of raceway groove is improved, and can bear bigger axial force, radial load and tilting moment, is driven also just
It is more steady, so as to solve the problems, such as that raceway groove fails.
