Description

Generator capable of preventing bearing from running out of outer ring

Technical Field

The utility model belongs to the technical field of the generator equipment technique and specifically relates to prevent that the bearing from running the generator of outer lane.

Background

The diesel generator is kinds of small-scale generating equipment, refer to the power machinery that uses diesel oil, etc. as the fuel, use the diesel engine as the prime mover to drive the generator to generate electricity, as shown in fig. 1-2, the outer end of central spindle of generator in the existing generator is fitted with the bearing, the bearing outer wall car has eccentric jump ring grooves, the jump ring is inlaid in the jump ring groove, while assembling, the highest point of jump ring rotates to the deepest of jump ring groove, then imbed the bearing into the mounting hole of the rear end cap of the generator, the outer wall of the bearing and inner wall of the mounting hole of the rear end cap bearing of the generator are the transition fit, in the course of putting into and operating, the jump ring can't jam rear end cap and bearing outer race in the above-mentioned structure, will cause the bearing to run out of the outer race, because the rear end cap of the generator is aluminium, the material is softer, cause the rear end cap of the generator to abrade seriously, the interval is enlarged, cause the rotor of the generator to tilt and stator to interfere, shorten the electrical machinery.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems that generators for preventing the bearing from running out of the outer ring are provided to overcome the defects in the prior art, the bearing outer ring can be clamped by the O-shaped ring, the bearing does not run out of the outer ring, and the rear end cover of the generator is not worn.

The utility model provides a generator that prevent that bearing from running the outer lane has generator rear end cap, bearing and generator center pivot, and the bearing is installed to generator center pivot outer end, and the bearing imbeds the bearing mounting hole of generator rear end cap, the ring channel has been seted up to the bearing mounting hole inner wall of generator rear end cap, has held O shape circle in the ring channel.

, the O-ring is in interference fit with the outer wall of the bearing to prevent the bearing from running out of the outer ring.

The utility model has the advantages that: the utility model discloses simple structure, reasonable in design, it is easy and simple to handle, the ring channel has been seted up to the bearing mounting hole inner wall of generator rear end cap, has held O shape circle in the ring channel, and O shape circle and bearing outer wall be interference fit, and this structure can block generator rear end cap and bearing inner race, prevents that the bearing from running the outer lane, does not lead to the fact wearing and tearing to the generator rear end cap, prolongs the life of generator, improves the generating efficiency of generator, has improved the silence performance of generator.

Drawings

The present invention will be further described in with reference to the accompanying drawings and embodiments.

FIG. 1 is an exploded view of a prior art structure;

FIG. 2 is a cross-sectional view A-A of FIG. 1;

fig. 3 is a schematic structural diagram of the present invention.

In the figure, 1 is a generator rear end cover, 2 is a bearing, 3 is a generator central rotating shaft, and 4 is an annular groove.

Detailed Description

The invention will now be described with reference to the accompanying drawings, which are simplified schematic drawings that are only schematic illustrations of the basic structure of the invention, and which therefore show only the components that are relevant to the invention.

The generator for preventing the bearing from running out of the outer ring as shown in fig. 3 is provided with a generator rear end cover 1, a bearing 2 and a generator central rotating shaft 3, wherein the bearing 2 is installed at the outer end of the generator central rotating shaft 3, the bearing 2 is embedded into a bearing installation hole of the generator rear end cover 1, an annular groove 4 is formed in the inner wall of the bearing installation hole of the generator rear end cover 1, and an O-shaped ring is accommodated in the annular groove 4; the O-shaped ring is in interference fit with the outer wall of the bearing 2.

The O-shaped ring is made of tough fluororubber with strength, and is not easy to age.

An O-shaped ring is arranged in the annular groove 4, the bearing 2 does not need to be adjusted in angle, and the bearing 2 is arranged in a bearing mounting hole of the rear end cover 1 of the generator by tapping the central rotating shaft 3 of the generator. O shape circle generator rear end cap blocks with the bearing inner race, prevents that the bearing 2 outer lane from following generator center pivot 3 to rotate, does not lead to the fact wearing and tearing to generator rear end cap 1, prolongs the life of generator.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable people skilled in the art to understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.

Claims
