Abstract
The utility model discloses a front bearing box being convenient for parallelism adjustment. Internal holes of the two ends of a box body are of through-hole structures; and an isolating ring is additionally arranged during assembly. The outside diameter of the isolating ring is matched with the inside diameter of through holes. The isolating ring is of an annular shape with a circular hole at the middle. After improvement, the bearing box has the advantages that the structure is simple, the accuracy of a drawing is very easily met during processing, the processing cost is reduced, and the accuracy of products is improved. The life is long, the average life of an original front bearing box is one year, and the average life of the improved front bearing box is five years, so that the cost of enterprises is greatly saved.
Description
Technical field
The present invention relates to a kind of front bearing box, particularly a kind of front bearing box of being convenient to regulate parallelism.
Background technique
Bearing housing is a kind of box parts that plays support and lubricating bearings effect, simultaneously, and the axial and radial force that the equipment that bears produces when work.In the equipment of running shaft was arranged, axle was generally got up to rotate by bearings, and bearing then is installed in the bearing housing, is marked with lubricant oil in the bearing housing, in the course of the work, used bearing to be lubricated.Simultaneously, axle suffered various power when work also can be delivered on the bearing housing, are carried by bearing housing.The material of bearing housing is generally cast iron and cast steel.Existing bearing housing housing structure is integrative-structure as shown in Figure 1, must reverse end for end processing owing to add man-hour two endoporus, so be difficult to parallelism and the requirement of beating in the control graph.Such bearing housing makes whole transmission system uneven, has affected the transmission accuracy of whole front bearing box.
Summary of the invention
The purpose of this utility model is: for the problem of above-mentioned existence, improve the integral structure of bearing housing of the prior art, directly made former casing two endoporus into through hole, and increased a spacer ring in when assembling, thereby the parallelism that only need adjust the spacer ring both ends of the surface just can guarantee the parallelism of bearing housing, has greatly simplified technique.
The technical solution adopted in the utility model is:
A kind of front bearing box of being convenient to regulate parallelism, casing two endoporus is the passing hole type structure, and increases a spacer ring when assembling.The external diameter of described spacer ring and the internal diameter of described through hole are complementary.Described spacer ring is middle round-meshed annular.
Owing to adopted technique scheme, the utlity model has following advantage:
1, the bearing housing after the improvement is simple in structure, is easy in the processing satisfy the drawing precision, has reduced processing cost, has improved Product Precision.
2, the life-span is long: original front bearing box mean lifetime is 1 year.Front bearing box mean lifetime after the improvement is 5 years, has greatly saved entreprise cost.
Description of drawings
Fig. 1 is the structural representation of fore bearing casing in the prior art;
Fig. 2 is a kind of structural representation of being convenient to regulate the front bearing box of parallelism of the utility model;
Fig. 3 is the structural representation of the spacer ring that matches with the utility model front bearing box;
Fig. 4 is the utility model front bearing box transmission schematic representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Specific embodiment described herein is only in order to explaining the utility model, and is not used in restriction the utility model.
Fig. 1 is the structural representation of fore bearing casing in the prior art.Existing fore bearing casing must be reversed end for end processing owing to add man-hour two endoporus, so be difficult to parallelism and the requirement of beating in the control graph.
The utility model is a kind of be convenient to regulate parallelism front bearing box structure as shown in Figure 2; The spacer ring structure that matches with it as shown in Figure 3.
A kind of front bearing box of being convenient to regulate parallelism, casing two endoporus is the passing hole type structure, and increases a spacer ring when assembling.The external diameter of described spacer ring and the internal diameter of described through hole are complementary.Described spacer ring is middle round-meshed annular.
Fig. 4 is the utility model front bearing box transmission schematic representation.When working, because casing two endoporus is the passing hole type structure, and increase a spacer ring when assembling, the parallelism that only need adjust the spacer ring both ends of the surface just can guarantee the parallelism of bearing housing, has greatly simplified technique.Bearing housing after the improvement is simple in structure, is easy to satisfy the drawing precision in the processing, has reduced processing cost, has improved Product Precision.Life-span is long, and original front bearing box mean lifetime is 1 year, and the front bearing box mean lifetime after the improvement is 5 years, has greatly saved entreprise cost.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
