Technical Field

The utility model relates to a bearing technology field, concretely relates to integrative holder structure convenient to dismouting is changed.

Background

The retainer is an important component of the bearing, is mainly used for separating rolling elements, reduces friction heat generated in the bearing operation, keeps the rolling elements evenly spaced, optimizes load distribution and reduces noise, guides the rolling elements when the bearing operates, simultaneously keeps the rolling elements of the separable bearing when a bearing ring is installed or disassembled, adopts a conventional bearing installation mode that an outer ring is arranged between the inner rings, the retainer is installed between the inner rings, then rollers are embedded into the retainer to form a set of bearing, the retainer cannot be taken out in such an installation mode, only can be damaged and taken out, and in case of special requirements, a retainer integral structure which can be replaced at any time without delaying time is urgently needed.

Disclosure of Invention

To the not enough of prior art, the utility model provides an integrative holder structure convenient to dismouting is changed, but the strong and self-change at any time of deformability.

The utility model discloses the technical scheme who adopts is the integrative holder structure of dismouting change of being convenient for, falls into spaced roller mounted position through the holder pillar on the holder, adjacent holder pillar between install the roller, the roller between two sets of holder pillars along the radial can impel the position of work center and release to dismantle the position center of bearing, the both sides wall of holder pillar have the radian, the radian looks adaptation of this radian and the outline of roller at the position of work center with dismantle position center two positions, the lateral wall of holder pillar is tightened up to the bearing inner circle from the bearing inner race.

Preferably, when the roller is located at the center of the dismounting position, a circle with a radius from a point of the roller farthest from the circle center of the bearing to the circle center of the bearing is used as the radius, and the diameter of the circle is smaller than or equal to the inner diameter of the end face of the outer ring of the bearing. The technical effects are as follows: the roller and cage assembly is removed from the bearing outer race.

The utility model has the advantages that: adopt the utility model discloses an integrative holder structure has overcome the technical problem that present holder takes out the difficulty, and the installation of being convenient for is dismantled, and the inspection is changed at any time, satisfies the demand of special case simultaneously, but the integrative holder of this structure is strong in strain capacity, when the roller goes wrong, can change by oneself at any time, need not shut down, does not hinder time, reduce cost again.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. The vertical direction described in the present invention is vertical from top to bottom in the drawing, and the horizontal direction is left to right in the drawing.

After the existing retainer, the roller and the inner ring and the outer ring of the bearing are installed, the retainer and the roller need to be taken out only by damaging the bearing, so that the bearing is required to have strong strain capacity according to the condition of special requirements, and the roller needs to be replaced at any time, as shown in figure 1, the retainer structure capable of being taken out integrally is designed, the roller needs to be replaced under the condition that the bearing is not damaged, and the replacement time is saved. The utility model discloses an integrative holder structure specifically includes holder 1, holder pillar 2, roller 3, holder 1 is spaced apart through holder pillar 2, roller 3 installs the intermediate position of adjacent two sets of holder pillars 2, holder pillar 2 sets to special shape, holder pillar 2 in the past only need according to roller 3's the outer radian looks adaptation design into corresponding radian can, holder pillar 2 of this application sets the radian that roller 3 can be released in the position that is close to the bearing inner circle, see figure 2 and show, in the design in the past, roller 3 only has a work position in the position on holder 1, this application roller 3 is there are two kinds in the position on holder 1, one kind is the work position, be close to the bearing inner circle, bearing inner circle installation back bearing rotatable position, after the bearing inner circle falls, roller 3 can release the dismouting position to the bearing inner circle, the dismouting of roller 3 of being convenient for is changed. A machining centre is also included in the present application, which serves to allow the rollers 3 to move radially back and forth.

The specific principle is as follows: firstly, the retainer pillar 2 is set into a pillar with a special shape, two sides of the retainer pillar 2 are set into a form with radians, the whole retainer pillar 2 is tightened from the outer ring of the bearing to the inner ring of the bearing, the side radians of the retainer pillar 2 are adapted to the pushing and pushing of the rollers 3 and pushed to a working position, the rollers 3 cannot be detached from the bearing inner ring, a bearing working structure is formed, the rollers are pushed inwards to a detaching position, when the rollers 3 are positioned at the detaching position center 5, the points of the rollers 3 farthest from the center of the bearing to the center of the bearing are used as a radius circle, and the diameter of the circle is smaller than or equal to the inner diameter of the end face of the outer ring of the bearing. The bearing outer ring is provided with an inward edge, so that the retainer 1 and the roller 3 are integrally pushed out, and the roller 3 is convenient to replace. Adopt the utility model discloses an integrative holder structure has overcome the technical problem that present holder takes out the difficulty, and the installation of being convenient for is dismantled, and the inspection is changed at any time, satisfies the demand of special case simultaneously, but the bearing of this structure is strong in strain capacity, when roller 3 goes wrong, can change by oneself at any time, need not shut down, does not hinder time, reduce cost again.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
