Description

A kind of high-accuracy bearing arrangement

Technical field

It the utility model is related to mechanical part, bearing arrangement technical field, more particularly to a kind of high-accuracy bearing arrangement.

Background technology

Bearing is that part that is fixed and reducing load coefficient of friction is played in mechanical transmission course.It may also be said that when other Parts when producing relative motion each other on axle, for reducing coefficient of friction and the holding shaft center in power transmission process Fixed parts.

Bearing is a kind of very important parts in contemporary plant equipment.Its major function is support machinery rotation Body, to reduce mechanical load coefficient of friction of the equipment in transmission process.By the difference of motor element frictional property, bearing can It is divided into rolling bearing and the class of sliding bearing two.

The inventors discovered that existing construction design of journal bearings is single, and all it is a single design mostly, using strong Spend it is lower slightly, a ball go wrong may result in it is overall decommissions, it is and poor for the fixing intensity of internal ball, so Need that existing bearing arrangement is further improved and optimized.

Then, I adhere to the relevant industries for many years it is abundant design and develop and the experience of actual fabrication, for existing Structure and missing are studied improvement, there is provided a kind of high-accuracy bearing arrangement, to reach with more more practical value Purpose.

Utility model content

The purpose of this utility model is to provide a kind of high-accuracy bearing arrangement, to solve what is proposed in above-mentioned background technology The problem of structure design is single, and use intensity is lower slightly, and ball fixing intensity is poor.

The purpose and effect of the high-accuracy bearing arrangement of the utility model, are reached by technological means in detail below：

A kind of high-accuracy bearing arrangement, wherein, the high-accuracy bearing arrangement includes：

Bearing body, bearing outer ring, ball, bearing inner race, raceway oil groove and bearing fixing hole；

Bearing inner race is provided with the inside of the bearing body；Bearing fixing hole is offered inside the bearing inner race；It is described Raceway oil groove is offered outside bearing inner race；Ball is provided with the raceway oil groove；On the inside of the bearing outer ring Offer the raceway oil groove corresponding with raceway oil groove.

Further, the bearing body is that four groups of bearings collectively form.

Further, the raceway oil groove designs for ramp-like configuration, and raceway oil groove described in one two two groups Corresponding angle is in 150 degree.

Further, offered on the raceway oil groove madial wall on the bearing inner race and bearing outer ring and ball Corresponding semi-spherical grooves.

With existing structure in comparison, the utility model has the following advantages that：

1. the utility model bearing body is the setting that four groups of bearings collectively form design, be advantageous to increase its use intensity And service life, prevent the damage of one of ball must the situations of repair and replacement occur, effectively improve operating efficiency and guarantor Ship sth. under guard and make machine.

2. the utility model raceway oil groove designs for ramp-like configuration, and the corresponding folder of one two two groups of raceway oil grooves Angle is in the setting of 150 degree of designs, is advantageous to design the fixing intensity for improving ball by angle tilt, prevents ball from revolving Turn to emerge from side, and effectively improve the operating smoothness that ball is surveyed inside.

3. offered on the raceway oil groove madial wall on the utility model bearing inner race and bearing outer ring and ball The setting of corresponding semi-spherical grooves, is advantageous to improve the intensity of fixed ball, and facilitates ball among the semi-spherical grooves Operating.
