Abstract

The utility model relates to a bulb separator for a bearing roller, aiming at solving the current technical problems of that a pin type bulb separator is difficult to be manufactured, a high damage rate of bulb separation and a low rate of bulb separation. The bulb separator head is formed by an arc roller groove and a crop bulb separator claw. The utility model has the advantages of easy manufacturing, a low damage rate of bulb separation, high rate of bulb separation, and can be extensively applied to finish the bulb separation in manufacturing bearings of all kinds of standards.

Description

The ball-distributer of bearing ball

(1) technical field: the utility model relates to the manufacturing installation or the apparatus of bearing, is specifically related to be used for the apparatus of bearing ball assembling.

(2) background technique: bearing will be separated into even distribution to the ball that concentrates between bearing inner race and the outer ring in manufacture process, be referred to as bulb separation.Ball-dividing device of the prior art and bulb separation process are seen Fig. 1: at first, bearing 4 is sent on the supporting base 6 by last work step by conveyor assembly, at this moment, by last work step the ball in the bearing is concentrated in together, and shown in Fig. 2 I state, 7 is the ball of bearing 4 among Fig. 2; Holding device 5 rises, and clamps the outer ring of bearing 4; Meanwhile, ball-distributer descends, and ball-distributer has a circular base 2, one end of matrix 2 has the connecting head that is connected with rotational power spare, the other end of matrix 2 is for dividing a bulb 3, and shown in Figure 1 minute bulb 3 is made of bulb separation pin separately, and the termination of described bulb separation pin is a pointed shape.During ball-distributer decline bulb separation, long bulb separation pin a at first inserts between two spin in center portion, and with two balls separately, shown in Fig. 2 II state, 8 is the space of bulb separation among the figure.Along with the continuation decline of ball-distributer, vice-minister's bulb separation pin b, c also separate the ball of relevant position toward both sides, as Fig. 2 III state.The rest may be inferred, and last spin integument more vice-minister's bulb separation pin d, e, f, g branch is opened, and becomes even distribution, as IV state among Fig. 2.

There is following shortcoming in above-mentioned pin type ball-distributer: bulb separation pin and divide the bulb difficulty of processing high, must be accurately before the bulb separation to the steel ball location, otherwise cause the bulb separation pin crooked and to a large amount of damages of bearing ball.For above-mentioned reasons, the pin type ball-distributer to the bulb separation rate of ball only about 90%, very high to the damage ratio of spin, almost reach 20%.

(3) summary of the invention: at existing pin type ball-distributer processing and installation difficulty height, to bearing ball damage ratio height and the low problem of bulb separation rate, the applicant improves after deliberation, design the ball-distributer of another kind of bearing ball, it can solve the problems referred to above that existing pin type ball-distributer exists largely.

The technical solution of the utility model is as follows:

The ball-distributer of bearing ball, it has a cylindrical base, and an end of cylindrical base has the connecting head that is connected with rotating shaft, and the other end of cylindrical base is for dividing a bulb, is characterised in that described minute bulb is by the arc ball grooves and tack bulb separation pawl is alternate constitutes; Described arc ball grooves is evenly spaced semi-circular groove; Described tack bulb separation pawl has uniform interval and identical height.

Because of the present utility model minute bulb is by the arc ball grooves and tack bulb separation pawl is alternate constitutes, avoid using most advanced and sophisticated shape bulb separation pin, by tack bulb separation pawl bearing ball is dialled in ball grooves one by one, therefore the damage ratio to bearing ball can effectively reduce during bulb separation, can effectively improve for the bulb separation rate of ball.The utility model processing also is easier to.

(5) embodiment:

See Fig. 3 to Fig. 6, the utility model has a cylindrical base 2, and an end of matrix 2 has the connecting head 1 of one with it, and perforate 6 is arranged on the connecting head 1, in order to inserting bolt, is connected with a connector by bolt, and connector is connected with rotating shaft, makes the utility model rotation.The other end of matrix 2 has the branch bulb 3 of one with it, divide bulb 3 to constitute by arc ball grooves 5 and tack bulb separation pawl 4 are alternate, arc ball grooves 5 and tack bulb separation pawl 4 are respectively evenly at interval, arc ball grooves 5 is shown Fig. 4 and tack bulb separation pawl 4 is respectively 7, according to the bearing of variety classes or specification, also can be other number.Arc ball grooves 5 the bests are semi-circular groove.

See Fig. 7, it is the schematic representation of the ball-dividing device that is made of the clamp holder of the utility model and bearing.Wherein 7 for treating the bearing of bulb separation, and 8 is the holding device of bearing, and 9 is the supporting base of bearing 7.Before the bulb separation, bearing 7 is sent on the supporting base 9 by a last work step by conveyor assembly, and the ball 10 in the bearing 7 concentrates in together at this moment, as Fig. 8 I state.During bulb separation, holding device 8 rises, and clamps the outer ring of bearing 7; Meanwhile, ball-distributer descends, and the connecting head 1 of ball-distributer is connected with the connector of rotating shaft.During connection, make the branch bulb 3 and horizontal plane inclination a small angle, for example 10 ° of angles of ball-distributer.When the branch bulb 3 of ball-distributer drops to the ball 10 that concentrates in together in the contact bearing 7, because the bulb separation head tilt has small angle, tack bulb separation pawl 4 is dialled in ball in the semicircular arc groove 5 rapidly one by one, shown in Fig. 8 state I I and III, ball is evenly distributed rapidly, finish the bulb separation process, 11 is space between the ball among Fig. 2.The connector of above-mentioned holding device 8, rotating shaft and other structures of ball-dividing device all adopt prior art.

During the utility model bulb separation to the damage ratio of ball in 6%, significantly reduce than the damage ratio (20%) of pin type ball-distributer.Its bulb separation rate is greater than 98%, raises significantly than the bulb separation rate (90%) of pin type ball-distributer.
