Description

The invention relates to mechanical engineering and the construction industry, namely to ball bearings. The aim of the invention is to expand technological capabilities, with increased reliability and simplification of the Design, as well as the perception of loads ranging from 30 ° to 60 ° from the vertical axis.

; In FIG. 1-3 shows the versions of the ball bearing, cuts; figure 4

- support structure for moving sheet blanks; Fig. 5 illustrates a construction for forcing movements of various devices; Fig. 6 shows the construction of supports for various pipe movements.

Structurally, the ball bearing is made as follows. In the housing 1 there is a nest of the bearing 2, in which balls of smaller diameter 3 are placed, enclosed in an annular separator 4. On balls of small diameter 3 laid with an annular bearing on them, a cargo ball 5, which is fixed on the back side to

case, removable threaded head 6. Part of the case 1 is made of a cylindrical step-shaped rectangular cross-section 7, in the upper part of which there is an internal thread 8 for a removable threaded head 6. The removable threaded head 6 is made cylindrical with an internal lodgement 9 for a cargo ball 5 and has an outer thread 10 for the housing 1, the flat ring track 11 of the bearing 2 is made with a cross-section for the radius of balls of small diameters 3. When the cargo ball 5 rotates around the vertical axis of the seat of the bearing-bearing 2 of the ball 3 and 4 together with the separator to rotate by rolling them along a circular path lozhementnoy, decoupling is the treadmill. Thus, when the cargo ball 5 rotates along the longitudinal axis of the separator 4, it will remain in place, and the balls 3 will rotate with friction clutch from the cargo ball inside the separator with rolling around the socket of the annular lodgement.

When the cargo ball 5 is rotated at any angle to the longitudinal axis or the vertical axis, the separator 4 will rotate together with the balls, which will simultaneously roll inside and around the annular lodgement.

Depending on the ratio of the diameters of the cargo ball and the inner ring, the set of balls in the bearing cage distributes the load on the cargo ball, transferring them from its center to the small balls with their corresponding emphasis to the radius of the lodgement race track, which ensures ball spacing in the ring bearing housing.

The angle of separation of small balls from the load perception by the load of the ball is different and depends on the design of the used bearing parts, taking into account the free gap between the separator and the body of the ball, i.e. at an angle of 30 ° a part of the design of a standard serial single-thrust ball bearing was used, at an angle of 60 ° a part of an angular contact bearing was used, and at an angle of 45 ° a special thrust ball bearing was used.

To simplify, due to the use of standard bearings in the support, designs as a thrust bearing seat 2 can be used with an outer ring placed in its treadmill, balls of a serial ball bearing enclosed in a separator, and to absorb loads up to 30 ° from the vertical

axis of the cargo ball along the annular perimeter as a bearing structures can be used a typical serial single-row ball bearing No. 12 without

another thrust ring. To accept loads up to 60 ° from the vertical axis of the cargo ball along the annular perimeter, typical serial angular contact structures can be used. Ball bearing No. 13 without inner ring. For perceiving loads up to 45 ° from the vertical axis of the cargo ball along the annular perimeter, support-thrust structures can be used

ball bearing No. 14.

In all applications of a typical ball bearing, the cargo balls are selected taking into account the free rotation of the separators on balls of smaller diameter without touching the ball, thereby obtaining the most optimal annular ball heel for the cargo ball.

As a result, technological capabilities are expanded with increased reliability and simplification of ball bearing designs. Using this design of typical supports, various new designs of devices and mechanisms can be created, and various

methods for positioning and moving products and devices in ball bearings in the field of engineering and construction. The invention will find wide application in all sectors of the national economy.
