Abstract
The utility model discloses a bearing configuration for a diving sewage pump. The bearing configuration comprises a shaft, an impeller and a deep groove ball bearing and is characterized in that an angular contact ball bearing and a cylinder roller bearing are arranged at the bottom of the shaft; and internal check rings and external check rings are between the angular contact ball bearing and the cylinder roller bearing. The bearing configuration has the advantages that the angular contact ball bearing is used for bearing the axial force and the cylinder roller bearing is used for bearing the radial force; and the internal check rings and the external check rings are used for guaranteeing the angular contact ball bearing and the cylinder roller bearing not to mutually interfere with each other.
Description
Technical field
The utility model relates to a kind of bearing configuration, the particularly improvement that bearing is disposed that is used for proof submersible sand discharging pump.
Background technique
The bearing of proof submersible sand discharging pump not only will bear axial force and also want bearing radial force, thus have only rational bearing configuration that proof submersible sand discharging pump is normally moved, otherwise water pump just can't move or the life-span reduces.Existing submersible sewage pump structure middle (center) bearing is configured to: the upper end is a deep groove ball bearing, and the lower end is the angular contact ball bearing of formula back-to-back.Because the radial force of large diving pollution discharge pump is very big, and the ability of back-to-back angular contact ball bearing bearing radial force is little,, be easy to cause the damage of deep groove ball bearing so radial force all will be born by the deep groove ball bearing of upper end greatly.And back-to-back angular contact ball bearing is very high to the play requirement, and just manufacturing and the installation requirement to bearing is all very high, has also increased cost of production greatly.
Summary of the invention
The purpose of this utility model is that the bearing that solves proof submersible sand discharging pump in the prior art disposes existing the problems referred to above, and a kind of novel bearing configuration is provided.A kind of bearing configuration that is used for proof submersible sand discharging pump of the utility model design, comprise axle, impeller, deep groove ball bearing, it is characterized in that: an angular contact ball bearing and a roller bearing are installed in the bottom of axle, inner shield ring and outer back-up ring are arranged in the middle of angular contact ball bearing and the roller bearing.The utility model has the advantages that angular contact ball bearing is used to bear axial force, roller bearing is used for bearing radial force, and the purpose of inner shield ring and outer back-up ring is to guarantee the two mutual noninterference.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is the original structure schematic representation; Accompanying drawing 2 is a structural representation of the present utility model.
Embodiment
Comprise axle 2, impeller 4, deep groove ball bearing 1 among the figure, it is characterized in that: an angular contact ball bearing 5 and a roller bearing 7 are installed in the bottom of axle 2, in the middle of angular contact ball bearing 5 and the roller bearing 7 inner shield ring 8 and outer back-up ring 6 are arranged.
At first an angular contact ball bearing is contained on the axle, loads onto inner shield ring and outer back-up ring then respectively, load onto a roller bearing at last.Wherein angular contact ball bearing is used to bear axial force, and roller bearing is used for bearing radial force.Its advantage is that two bearings have born axial force and radial force respectively, and the purpose of inner shield ring and outer back-up ring is to guarantee the two mutual noninterference.Because the roller bearing bearing radial force is very capable, so just reduced the radial force that deep groove ball bearing bore of upper end greatly, prolong its working life.
Claims (1)
