Abstract
The utility model belongs to the technical field of the technique of end cap seal equipment for the casing and specifically relates to an end cover and bearing installation device is related to, the middle part on the medial surface of end cover is equipped with the installation cavity of bearing, installs the bearing in the installation cavity, being equipped with annular mounting groove on the inside wall of installation cavity, being equipped with O type circle between the outer lane of mounting groove and bearing, the outer lane diameter of bearing is less than the diameter of installation cavity. The advantage is: structure through to the end cover improves, has improved the relation of connection between bearing and the installation cavity simultaneously, adopts non - interference fit between bearing and the installation cavity to through adding cooperation relation between the O type of establishing circle reinforcing bearing and the installation cavity, can effectively reduce the wearing and tearing of bearing like this, reduce equipment trouble and rate and reduced because of the noise that the bearing wear produced, simultaneously the bearing the installation accuracy with require also corresponding reduction, the operation of being convenient for has also improved the life of product.
Description
Technical field
The utility model relates to the technical field of casing end cap equipment, especially relates to a kind of end cap and bearing Mounting device.
Background technique
Usually all play a part very important at the end cap of the casings such as water pump at present, to the usability of complete machine and play vital effect the working life of product.Under normal circumstances, the middle part on the inner side surface of end cap traditional is at present provided with the installation cavity of bearing, is provided with bearing in installation cavity, is provided with the penetration hole communicated with the outer side surface of end cap at the bottom of the chamber of installation cavity.Between bearing outer ring and installation cavity is utilize the mode of interference fit to carry out installation to ensure that bearing outer ring does not operate with bearing inner race mostly, and make bearing failure, but easily cause ball and the raceway groove damage of bearing in installation process, the whole service life of bearing and product is caused to reduce, in addition because bearing wear, cause that the noise of equipment is large, vibration increases, simultaneously the accuracy of manufacturing of bearing and installation precision require very high, operation also difficulty extremely, directly has influence on the financial cost of product.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of damage ratio reduced in bearing installation process, reduces equipment failure rate, reduces installation precision and equipment noise, improves end cap and the bearing Mounting device in the working life of product.
For realizing above-mentioned object, the utility model provides following technological scheme:
A kind of end cap and bearing Mounting device, middle part on the inner side surface of end cap is provided with the installation cavity of bearing, in installation cavity, bearing is installed, the madial wall of described installation cavity is provided with the mounting groove of annular, be provided with O type circle between mounting groove and the outer ring of bearing, the race diameter of bearing is less than the diameter of installation cavity.
The utility model is set to further: the axial height of bearing is not more than the axial height of installation cavity.
By adopting technique scheme, the technique effect that the utility model reaches is: by improveing the structure of end cap, improve the annexation between bearing and installation cavity simultaneously, non-interference fit is adopted between bearing and installation cavity, and strengthen matching relationship between bearing and installation cavity by adding O type circle, the wearing and tearing of bearing can be effectively reduced like this, reduce equipment failure rate and reduce the noise because bearing wear produces, the installation precision of bearing also reduces accordingly with requiring simultaneously, convenient operation, also improves the working life of product.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is sectional structure principle schematic of the present utility model.
Embodiment
With reference to Fig. 1, a kind of end cap and bearing Mounting device disclosed in the utility model, middle part on the inner side surface of end cap 10 is provided with the installation cavity of bearing 11, bearing 11 is installed in installation cavity, the madial wall of installation cavity is provided with the mounting groove of annular, be provided with O type circle 12 between the outer ring of mounting groove and bearing 11, the race diameter of bearing 11 is less than the diameter of installation cavity, and the axial height of bearing 11 is not more than the axial height of installation cavity.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
