Abstract

The invention discloses a double slewing bearing. The double slewing bearing mainly comprises a base, two slewing support assemblies with the same structure which are symmetrically distributed at the two sides of the base, wherein the base is a square plate, fixed orifices are formed in the four angulus parietalis of the base, each slewing support assembly comprises two support plates with the same structure and a fixed block, the two support plates are welded vertically on the base and are parallel with each other, reamed holes with the same size are respectively arranged at the centers of the two support plates, a wear-resistant coating is coated in the reamed holes, the fixed blocks are welded between the two support plates, and are provided with mounting holes for mounting guide pins. According to the double slewing bearing disclosed by the invention, the strength requirement under a heavy load situation can be guaranteed, simultaneously, the soldering form is adopted, so that wholistic processing cost is lower, and the double slewing bearing can be used widely.

Description

A kind of dual AC power bearing

Technical field

The present invention relates to mechanical fitting field, be specifically related to a kind of dual AC power bearing.

Background technique

At present, most of machinery all needs use pivoting support, but pivoting support of the prior art adopts the mode of overall digital control processing mostly, cause the fabricating cost of single pivoting support higher, can not accept by masses, meanwhile, adopt the pivoting support of digital control processing mode to cause its bulk strength poor because of its structural limitations, some underloading application operating modes can only be met, and meet its requirement of strength for being difficult under case of heavy load.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of dual AC power bearing, this pivoting support adopts welding method to process, and simultaneously its structure can meet the requirement of strength under case of heavy load.

Object of the present invention carrys out specific implementation by the following technical programs:

A kind of dual AC power bearing, mainly comprise base and the identical revolving support assembly of two groups of structures, two groups of revolving support assemblies are symmetrically distributed in the both sides of base, described base is square plate, four drift angle places of base are provided with fixed hole, the described revolving support assembly often organized comprises two identical dunnages and fixed block, two dunnages are parallel to each other and are vertically welded on base, the identical fraising of size is provided with in the center of two dunnages, wear resistant coating is coated with in described fraising, described fixed block is welded between two dunnages, described fixed block is provided with the mounting hole for installing guide finger.

Described each dunnage is square plate and at its Jun Daoyou oblique angle, top.

A kind of dual AC power bearing of the present invention, pivoting support comprises base and is symmetrically distributed in the identical revolving support assembly of two groups of structures on base, often organize revolving support assembly and comprise two identical dunnages and fixed block, be provided with in the center of same ancestral's dunnage and ream and be coated with wear resistant coating, requirement of strength under adopting this kind of structure can ensure case of heavy load, adopt the form of welding simultaneously, make overall processing cost low, can be widely used.

Accompanying drawing explanation

According to drawings and embodiments the present invention is described in further detail below.

Fig. 1 is the structural representation of a kind of dual AC power bearing of the present invention.

In figure: 1-base; 2-dunnage; 3-fixed hole; 4-reams; 5-fixed block; 6-mounting hole; 7-oblique angle.

Embodiment

As shown in Figure 1, a kind of dual AC power bearing described in the embodiment of the present invention, mainly comprise base 1 and the identical revolving support assembly of two groups of structures, two groups of revolving support assemblies are symmetrically distributed in the both sides of base 1, base 1 is square plate, four drift angle places of base 1 are provided with fixed hole 3, often organize revolving support assembly and comprise two identical dunnages 2 and fixed block 5, two dunnages 2 are parallel to each other and are vertically welded on base 1, the identical fraising of size 4 is provided with in the center of two dunnages 2, wear resistant coating is coated with in fraising 4, fixed block 5 is welded between two dunnages 2, fixed block 5 is provided with the mounting hole 6 for installing guide finger.

Preferred embodiment, each dunnage 2 is square plate and at its Jun Daoyou oblique angle, top 7 to one.

A kind of dual AC power bearing of the present invention, pivoting support comprises base and is symmetrically distributed in the identical revolving support assembly of two groups of structures on base, often organize revolving support assembly and comprise two identical dunnages and fixed block, be provided with in the center of same ancestral's dunnage and ream and be coated with wear resistant coating, in use, axle is arranged in fraising 4, the sidewall of axle is provided with guiding groove, and in mounting hole 6, be provided with the guide finger cooperatively interacted with guiding groove, axle can move along its axial direction, guide finger plays spacing effect, requirement of strength under adopting this kind of structure can ensure case of heavy load, adopt the form of welding simultaneously, make overall processing cost low, can be widely used.

Last it is noted that the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; it still can regulate the technological scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
