Abstract
The utility model discloses a welding holder with struts, comprising a big gasket (1) with a screwed hole, a small gasket (3) with a unthreaded hole and a group of struts (2), wherein at least one portable pillar is arranged in the struts, one end of the portable pillar has a cylindrical boss (4), a locating hole (5) through which a steel wire or a pin penetrates is arranged in the radial direction of the cylindrical boss (4), an optical axis (6) is arranged in the middle, the other end is provided with a screw thread (7) connected with the screwed hole on the big gasket (1), and locating slots (8) through which the steel wire or the pin penetrates are respectively arranged at both sides of the unthreaded hole on the small gasket (3) corresponding to the cylindrical boss (4). The welding holder with struts, obtained by improving the present holder, principally solves the problem that the slag is difficult to be removed after the holder is welded, and can clearly know the use condition of the surface of the inner raceway in time.
Description
Technical field
The utility model belongs to technical field of bearings, and what relate generally to is single, double, that four-row tapered roller bearing adopts a kind of pillar welding retainer.This bearing is mainly used in mine, metallurgy industry.
Background technique
In the mine, metallurgy industry, general single, double, the four-row tapered roller bearing of Cai Yonging, as shown in Figure 1, retainer wherein adopts pillar welding retainer.The structural type of pillar welding retainer all is made up of small washer 3 and one group of pillar 2 of a large washer with threaded hole 1, a band unthreaded hole, pillar 2 one end band grooves as shown in Figure 2, and the other end is threaded, and intermediate portion is an optical axis.During the bearing assembling, the threaded end of pillar is screwed in the tapped hole of large washer 1, load onto hollow roller, the other end is welded on the small washer 3 of band unthreaded hole then.In welding process, have welding slag inevitably and enter in the raceway, because the gap between roller and the roller is very little, welding slag is difficult to remove fully clean.If bearing inside is unclean, even have hard foreign matter to enter, bearing is with very fast inefficacy.
Summary of the invention
The purpose of this utility model provides a kind of new t shore welding retainer, is mainly used in and solves the problem that retainer welding back welding slag is difficult to remove, and can in time, clearly understand the behaviour in service on inner ring raceway surface.
The purpose of this utility model can adopt following technological scheme to realize: its small washer and one group of pillar by a large washer with threaded hole, a band unthreaded hole constitutes, has a portable stanchion in the described pillar at least, the one end has cylindrical boss, radially be provided with the positioning hole that is used for by steel wire or pin at cylindrical boss, the centre is an optical axis, and the other end is provided with the screw thread that is connected with the large washer upper screwed hole; Unthreaded hole both sides on described and the corresponding small washer of cylinder boss are respectively arranged with the locating slot that is used for by steel wire or pin.
The described cylindrical boss positioning hole radially that is positioned at is two (drilling through) or four (not drilling through).
The described quantity that is positioned at each side locating slot of the unthreaded hole both sides on the minipad is one.
Because portable stanchion one end is not welded on the retainer pad, therefore can dismantle at any time.This pillar and last rolling element position similarly are to have opened a window on bearing, can be with the convenient taking-up of the foreign matter in the raceway, the behaviour in service that can also in time, clearly check the inner ring raceway surface.

Embodiment
The accompanying drawings specific embodiment of the utility model.
The described pillar of the utility model welding retainer is to carry out improvedly on original retainer basis, and its overall structure also is made of small washer 3 and one group of pillar 2 of a large washer with threaded hole 1, a band unthreaded hole.Shown in accompanying drawing 3,4,5,6,7, have a portable stanchion in the pillar described in the utility model at least, present embodiment is a portable stanchion, and the one end has cylindrical boss 4, radially be provided with the positioning hole 5 that is used for by steel wire or pin at cylindrical boss 4, present embodiment is two; The centre is an optical axis 6, and the other end is provided with the screw thread 7 that is connected with large washer 1 upper screwed hole; Cylindrical boss 4 diameters are bigger than intermediate light axial region position 6.Described positioning hole 5 is two (drilling through) or four (not drilling through), and present embodiment is two.Unthreaded hole both sides on described and the cylinder boss 4 corresponding small washers 3 are respectively arranged with the locating slot 8 that is used for by steel wire or pin.The quantity of locating slot is at least one.Unthreaded hole both sides in the present embodiment on the small washer 3 are respectively arranged with a locating slot.Groove depth is advisable can hold a steel wire or pin.Fix by steel wire or pin between cylindrical boss 4 and the locating slot 8.Present embodiment adopts steel wire 9 fixing.
The utility model, was installed to roller, pillar 2 between two packing rings shown in accompanying drawing 6,7 in when assembling, and pillar one end screws in the tapped hole on the big pad, and the other end is welded in the unthreaded hole of small washer, forms overlay cladding 10.At least the portable stanchion 11 that keeps a roller and a radial bore.After welding slag on the retainer after the welding and the removing totally of the welding slag in the inner ring raceway, again this last root portable stanchion is passed hollow roller and be installed between two pads.Because this pillar has only an end to fix (threaded end screws), an other end adopts steel wire or pin to insert in the positioning hole of portable stanchion head, again steel wire or pin are fixed in the locating slot on the small washer, can effectively prevent the loose or dislocation of portable stanchion like this.
