Abstract
The utility model provides a kind of rotating ring with square cross section between outer land, including the oil guiding hole in rotating ring ring wall, the ring week of rotating ring is provided with two layers of step, it is characterised in that, the quantity of the oil guiding hole is 28, and the cross section of the between outer land in two layers of step is square.The oil guiding hole is facing each other.Described oil guiding hole etc. is divided into the ring wall of rotating ring.The utility model has the advantage of because the cross section of rotating ring between outer land is square, the cooperation between rotating ring and machine seal ring seat is closer, even if persistently carrying out circular motion, it will not also skid, while adding multiple oil guiding holes, the inflow velocity of lubricating oil can be improved, lubricant effect is thus significantly increased.For synthesis, the sealing effectiveness of part can be kept, extends the service life of product.
Description
Technical field
The utility model is related to a kind of rotating ring with square cross section between outer land, and it is difficult to produce skidding with machine seal ring seat,
And with the multiple oil guiding holes for possessing more preferable lubricant effect, belong to machine component field.
Background technology
Existing rotating ring is operated together with typically coordinating with machine seal ring seat.As shown in Figure 1, 2, one leads on rotating ring ring wall
Hole, for injecting lubricating oil, to rotating ring, the power transmission shaft internal with it is lubricated.But an empty design of Oil Guide frequently results in profit
Lubricating oil inflow velocity is slow, the easily degree of wear of increase part, and produce high temperature.In addition, the cross section of rotating ring between outer land 2 is circular
, coordinate with machine seal ring seat and circle, be also easy to produce skiddings between working time long two parts, significantly affect sealing and imitate
Really, the service life of product is further shortened.
The content of the invention
The purpose of this utility model is to provide a kind of rotating ring with square cross section between outer land, with more preferable lubricant effect
And be difficult to skid with machine seal ring seat.
To realize object above, the utility model provides a kind of rotating ring with square cross section between outer land, including located at dynamic
Oil guiding hole in ring ring wall, the ring week of rotating ring is provided with two layers of step, it is characterised in that the quantity of the oil guiding hole is 2-8,
The cross section of between outer land in two layers of step is square.The oil guiding hole is facing each other.Described oil guiding hole etc. is divided into dynamic
In the ring wall of ring.
The utility model has the advantage of because the cross section of rotating ring between outer land is square, between rotating ring and machine seal ring seat
Cooperation it is closer, even if persistently carrying out circular motion, will not also skid, while adding multiple oil guiding holes, profit can be improved
The inflow velocity of lubricating oil, thus significantly increases lubricant effect.For synthesis, the sealing effectiveness of part can be kept, extends product
Service life.
Brief description of the drawings
Fig. 1 is the horizontal midship section figure of existing rotating ring；
Fig. 2 is existing rotating ring top view；
Fig. 3 is the horizontal midship section figure of rotating ring that the utility model is related to；
Fig. 4 is the rotating ring top view that the utility model is related to.
Embodiment
Below in conjunction with drawings and examples, the utility model is described in further detail.
Embodiment
As shown in Figure 3,4,2-8 oil guiding hole 3 is provided with the ring wall of rotating ring 1, these oil guiding holes 3 are that decile is distributed in rotating ring
In 1 ring wall, and when the quantity of oil guiding hole 3 is even numbers, the position of oil guiding hole 3 is facing each other.The ring week of rotating ring 1
On have two layers of step, wherein, the cross section of between outer land (2 ') is square on the whole.
In use, the between outer land (2 ') of rotating ring 1 with machine seal ring seat with being connected, operation together.Due between outer land (2 ')
Cross section be square on the whole, its between outer land (2) with the more existing rotating ring 1 of resistance of machine seal ring seat junction greatly, is difficult to beat
It is sliding.In addition, adding lubricating oil by multiple oil guiding holes 3, the inflow velocity of lubricating oil can be obviously improved, lubricant effect is improved.Knot
Two improvement are closed, the sealing property of part can be kept, extend the service life of product.
Claims (3)
1. a kind of rotating ring with square cross section between outer land, including the oil guiding hole (3) in rotating ring (1) ring wall, rotating ring (1)
Ring week is provided with two layers of step, it is characterised in that the quantity of the oil guiding hole (3) is 2-8, the between outer land (2 ') in two layers of step
Cross section be square.
2. the rotating ring according to claim 1 with square cross section between outer land, it is characterised in that the oil guiding hole (3) two
Two is relative.
3. the rotating ring according to claim 2 with square cross section between outer land, it is characterised in that described oil guiding hole (3) etc.
In the ring wall for being divided into rotating ring (1).
