The invention has the beneficial effects as follows: the bolt connection pair with restricting element of the present invention, cross oil draining bolt side
Wall is provided with labyrinth type throttle orifice and connected, by this labyrinth type throttle orifice, the mistake that whelk stricture of vagina is outer and crosses in oil draining bolt
Oil duct, the circulation path of labyrinth type throttle orifice is labyrinth-like, i.e. its circulation path has one or more bending
Portion, enters in oil channel from the fluid crossed outside oil draining bolt by this labyrinth type throttle orifice, curved through these
During folding part, the flow direction of fluid will change, and then realizes restriction effect, makes the flow velocity of fluid necessarily be controlled
System, it is to avoid in crossing oil draining bolt, cavitation, flash distillation, vibration and noise problem occur.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation crossing oil joint of the present invention；
Fig. 2 is the structural representation crossing oil draining bolt of the present invention；
Fig. 3 is the sectional view in Fig. 2 at A.
Detailed description of the invention
Fig. 1 is the structural representation of the present invention；Fig. 2 is the driven wheel structure schematic diagram of the present invention；Fig. 3 is
The sectional drawing of the driving shaft of the present invention, the throttle type of the present embodiment crosses oil draining bolt 8 auxiliary connection, including whelk
Bolt 8 and with described cross oil draining bolt 8 by threaded engagement be connected cross oil joint, described mistake oil draining bolt 8 spiral shell
Bar 9 is provided with oil channel 11 vertically and screw rod 9 sidewall is provided with the labyrinth-like throttling connected with this oil channel 11
Hole, the circulation path of labyrinth type throttle orifice is labyrinth-like, i.e. its circulation path has one or more bending part,
Enter in oil channel 11 from the fluid crossed outside oil draining bolt 8 by this labyrinth type throttle orifice, curved through these
During folding part, the flow direction of fluid will change, and then realizes restriction effect, makes the flow velocity of fluid necessarily be controlled
System, it is to avoid in crossing oil draining bolt 8, cavitation, flash distillation, vibration and noise problem occur.
In the present embodiment, described labyrinth-like oil-through hole 7 includes a sprue 10 being interconnected and multiple points
Runner 12, sprue 10 one end connects with oil channel 11, and the other end is by sub-runner 12 and crosses oil draining bolt 8
Outside connection, fluid produces in the intersection at sprue 10 with sub-runner 12 and interacts, thus enters one
Step reduces the flow velocity of medium.
In the present embodiment, the described joint of oil excessively includes barrel-shaped joint body, described joint body 5 two ends of oil excessively
Being provided with and cross the screw 3 that coordinates of oil draining bolt 8, described mistake is provided with barrel-shaped mistake oil pocket 4 and this mistake inside oil joint
The minimum diameter of oil pocket 4 is more than the diameter of screw 3, and this internal diameter crossing oil pocket 4 is gradually subtracted to two ends by centre
Little, crossing oil pocket 4 is that middle internal diameter is big, and the barrel-shaped inner cavity that two ends internal diameter is little compares existing cylindrical cavity
For, the inner surface surface area of this barrel-shaped inner cavity is relatively big, therefore, it is possible to effectively reduce liquid to crossing oil joint
The pressure of inner chamber, on the other hand, the arc-shaped inner surface of barrel-shaped inner cavity can effectively cut down the percussion of liquid,
It was greatly improved the service life of oil joint.
In the present embodiment, described oil-through hole 7 along cross oil draining bolt 8 radially uniform be distributed multiple, thus increase into
Enter the liquid communication area of section in oil draining bolt 8, reduce the flow resistance of liquid, on the other hand, this edge
The external force that the equally distributed oil-through hole 7 of circumference can make oil draining bolt 8 suffered in the course of the work more balances,
Avoid oil draining bolt 8 that concentrated wear occurs after long-term use, improve its service life.
The present embodiment transverse and longitudinal, described barrel-shaped joint body sidewall is provided with for the jack 2 of oil excessively with oil pipe 1 grafting, should
Can be provided for the female thread that be connected fixing with oil pipe 1 in crossing oil jack 2, certainly, this female thread can use
Seal of tube bolt is to improve the sealing property of link position.
In the present embodiment, described oil jack 2 of crossing is more than the bellmouth 6 of inner side internal diameter, therewith for outside internal diameter
The oil pipe 1 connected can be the flexible ducts such as rubber tube, during this pipeline inserts in bellmouth 6, and oil
Oil pipe 1 by the most inside extruding force of bellmouth 6, thus will be improved with the most oily in pipe 1 front end
The sealing property that jack 2 connects.
In the present embodiment, being provided with restricting element in described oil-through hole 7, restricting element can effectively control stream
The speed of body, it is to avoid cavitation, flash distillation, vibration and noise occurs in pipeline, or can be arranged by oil-through hole 7
Multiple kinks are to realize restriction effect, i.e. oil-through hole 7 includes a sprue 10 being interconnected and multiple
Sub-runner 12, sprue 10 one end connects with oil channel 11, and the other end passes through each sub-runner 12 with the most oily
Joint inner space.
In the present embodiment, it is provided with sealing ring between described oil joint excessively and excessively oil draining bolt 8 head, it is to avoid fluid oozes
Leakage.
In the present embodiment, described oil-through hole 7 to distance bottom oil draining bolt 8 screw rod 9 be more than oil pocket 4
Height, therefore by regulating oil draining bolt 8 relative to the axial location crossing oil joint, can be by making
It is outer to realize blocking the circulation of fluid that oilhole 7 was fully located at oil joint inner chamber.
Although being described in detail the present invention with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from skill of the present invention
The objective of art scheme and scope, it all should be contained in the middle of scope of the presently claimed invention.
