The depth of the one end of sink far from the main shaft.
The taper positioned at the outer surface of the ring body is additionally provided on the ring body as a preferred technical solution,
The small end of water dumping cylinder, the taper water dumping cylinder is fixedly mounted on the ring body, the taper water dumping cylinder and the annular
Ontology coaxial arrangement.
The root of the taper water dumping cylinder is equipped with through-hole as a preferred technical solution, and the through-hole leads to the water dumping
The outer surface of ring.
As a preferred technical solution, the inner surface and the outer surface of the taper water dumping cylinder be equipped with radially extend it is recessed
Slot, depth of the groove adjacent to one end of the root of the taper water dumping cylinder are greater than the depth of the outer end of the groove.
The groove and the through-hole are interconnected as a preferred technical solution,.
The diameter of the ring body is greater than the diameter of the big end of the taper water dumping cylinder as a preferred technical solution,.
By adopting the above-described technical solution, a kind of water pump shaft connecting bearings, including main shaft and outer ring, the main shaft and described
It is equipped with roller between outer ring, water seal is equipped between the both ends of the outer ring and the main shaft main shaft, the main shaft is adjacent to described
One end of water pump inner cavity is equipped with throw rijng；Water is thrown away by throw rijng, so as to avoid water from water seal enter main shaft and outer ring it
Between, caused bearing damage.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the embodiment of the present invention one；
Fig. 2 is the structural schematic diagram of throw rijng in the embodiment of the present invention two；
Fig. 3 is the partial enlarged view in Fig. 2 at I.
Specific embodiment
Embodiment one:
As shown in Figure 1, a kind of water pump shaft connecting bearings, including main shaft 1 and outer ring 2, between the main shaft 1 and the outer ring 2
Equipped with roller 3, water seal 4 is equipped between the both ends of the outer ring 2 and the main shaft main shaft 1, the main shaft 1 is adjacent to the water pump
One end of inner cavity is equipped with throw rijng 5.Water is thrown away by throw rijng, is entered between main shaft and outer ring so as to avoid water from water seal,
Caused bearing damage.
Embodiment two:
As shown in Figures 2 and 3, the structure of the structure of embodiment two and embodiment one is essentially identical, the difference is that, institute
Stating throw rijng 5 includes ring body 6, and the inner hole of the ring body is connected with the sleeve 11 covered outside the main shaft, the ring
The outer surface of shape ontology 6 adjacent to the water pump inner cavity and be equipped with the radial sink 7 that radially extends.
The depth of the one end of the radial direction sink 7 adjacent to the main shaft is greater than the radial sink far from the main shaft
The depth of one end.It allows the water to easier throw away from radial sink in this way.
The taper water dumping cylinder 8 positioned at the outer surface of the ring body 6, the taper are additionally provided on the ring body 6
The small end of water dumping cylinder 8 is fixedly mounted on the ring body 6, the taper water dumping cylinder and ring body coaxial arrangement.
Taper water dumping cylinder favours the outer surface of ring body, and water is thrown away by the inclination of taper water dumping cylinder, increases the direction of water dumping, improves
The efficiency of water dumping.
The root of the taper water dumping cylinder 8 is equipped with through-hole 9, and the through-hole 9 leads to the outer surface of the throw rijng 5.
The inner surface and the outer surface of the taper water dumping cylinder 8 is equipped with the groove 10 radially extended, and the groove 10 is neighbouring
Depth in one end of the root of the taper water dumping cylinder 8 is greater than the depth of the outer end of the groove 10.
The groove 10 is interconnected with the through-hole 9.Water can enter groove by through-hole and be got rid of again by taper maching wringing tube
Out.
