Abstract

The utility model provides a two slide mass fluted shafts hold, relates to a bearing, is close to both ends punishment in outer lane inner wall (3) of outer lane (2) and do not is equipped with shallow slot (10), inner circle outer wall (5) of inner circle (7) are close to both ends punishment and do not are equipped with semicircle slot (6), a plurality of balls (4) that two annulars were arranged are in the two halves circle slots (6) of inner circle (7), and shallow slot (10) the card of outer lane (2) is in a plurality of balls (4) outer fringe that two annulars were arranged, the utility model discloses a ball sets up the ball that two rings shapes was arranged between outer lane and inner circle, the stability of acquireing outer lane and inner circle by two rings of balls, the utility model has the advantages of anti -seismic performance is good, the swing is little.

Description

A kind of two slide mass groove bearing

[technical field]

The utility model relates to a kind of bearing, especially relates to a kind of two slide mass groove bearing.

[background technique]

Known, bearing is a kind of important spare part in contemporary machinery, the major function of bearing is supported mechanical solid of rotation, reduce the friction factor of mechanical solid of rotation in movement process, and ensure its rotating accuracy, conventional bearing is single roll structure, in the using process of bearing thrust load, easily occurs swinging.

[summary of the invention]

In order to overcome the deficiency in background technique, the open a kind of two slide mass groove bearing of the utility model, arranges the ball of two circle annular array by ball between outer ring and inner ring, obtains the stable of outer rings and inner ring by two circle balls; Effectively overcome the drawback that swinging easily appears in existing single ball.

For achieving the above object, the utility model adopts following technological scheme:

A kind of two slide mass groove bearing, comprises outer ring, ball and inner ring, is respectively equipped with shallow slot at the outer ring inwall of outer ring near two ends place; The interior ring outer wall of inner ring is respectively equipped with semicircle groove near two ends place; A plurality of balls of two annular array are in the two semicircular groove of inner ring, and the shallow slot of outer ring is stuck in a plurality of ball outer rims of described two annular array.

Described two slide mass groove bearings, the outer ring outer wall of outer ring is ring plain.

Described two slide mass groove bearings, the two ends of outer ring outer wall and outer ring are chamfered transition.

Described two slide mass groove bearings, the inner ring inwall of inner ring is ring plain.

Described two slide mass groove bearings, the two ends of inner ring inwall and inner ring are chamfered transition.

Owing to adopting technological scheme as above, the utility model has following beneficial effect:

Described in the utility model pair of slide mass groove bearing, supports outer ring and inner ring by the ball of two circle annular array, just can overcome the drawback that the swing of prior art is large during use; The utility model have anti-seismic performance good, swing the advantages such as little.

[accompanying drawing explanation]

Fig. 1 is structural representation of the present utility model;

Fig. 2 is outer ring structure schematic diagram of the present utility model;

Fig. 3 is inner ring structure schematic diagram of the present utility model;

In figure: 1, outer ring outer wall; 2, outer ring; 3, outer ring inwall; 4, ball; 5, interior ring outer wall; 6, semicircle groove; 7, inner ring; 8, chamfering; 9, inner ring inwall; 10, shallow slot.

[embodiment]

Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples;

Two slide mass groove bearings by reference to the accompanying drawings described in 1,2 or 3, comprise outer ring 2, ball 4 and inner ring 7, the outer ring outer wall 1 of outer ring 2 is ring plain, and outer ring outer wall 1 is chamfering 8 transition with the two ends of outer ring 2, is respectively equipped with shallow slot 10 at the outer ring inwall 3 of outer ring 2 near two ends place; The inner ring inwall 9 of inner ring 7 is ring plain, and inner ring inwall 9 is chamfering 8 transition with the two ends of inner ring 7, and the interior ring outer wall 5 of inner ring 7 is respectively equipped with semicircle groove 6 near two ends place; A plurality of balls 4 of two annular array are in the two semicircular groove 6 of inner ring 7, and the shallow slot 10 of outer ring 2 is stuck in a plurality of balls 4 outer rim of described two annular array.

Implement described in the utility model pair of slide mass groove bearing, installation process is: the two semicircular groove 6 first multiple ball 4 being put into inner ring 7, then instrument is used outer ring 2 to be pressed down a plurality of balls 4 outer rim being enclosed within two annular array, by the ball 4 of two circle annular array support ball 4 that outer ring 2 and inner ring 7, two enclose annular array interact obtain anti-seismic performance good, swing little bearing.

The non-detailed portion of the utility model is prior art.
