Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structural representation of the oily joint of mistake of the present utility model;
Fig. 2 is the structural representation crossing oil draining bolt of the present utility model;
Fig. 3 is the sectional view at A place in Fig. 2.
Embodiment
Fig. 1 is structural representation of the present utility model, Fig. 2 is driven wheel structure schematic diagram of the present utility model, Fig. 3 is the sectional view of driving shaft of the present utility model, the throttle type of the present embodiment crosses oil draining bolt 8 auxiliary connection, the oily joint of mistake comprising oil draining bolt 8 and be connected by screw-thread fit with described oil draining bolt 8 excessively, the described screw rod 9 crossing oil draining bolt 8 is provided with oil channel 11 vertically and screw rod 9 sidewall is provided with the labyrinth-like throttle orifice be communicated with this oil channel 11, the circulation path of mazy type throttle orifice is labyrinth-like, namely 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 mazy type throttle orifice, passing through these kinks, the flow direction of fluid will change, and then realize restriction effect, the flow velocity of fluid is necessarily controlled, avoided occurring cavitation in oil draining bolt 8, flash distillation, vibration and noise problem.
In the present embodiment, described labyrinth-like oil-through hole 7 comprises the sprue 10 and multiple runner 12 that are interconnected, sprue 10 one end is communicated with oil channel 11, the other end is communicated with outside mistake oil draining bolt 8 by runner 12, fluid produces in the intersection at sprue 10 and runner 12 and interacts, thus reduces the flow velocity of medium further.
In the present embodiment, the oily joint of described mistake comprises barrel-shaped joint body, described mistake oily joint body 5 two ends are provided with the screw 3 coordinated with mistake oil draining bolt 8, described mistake oily joint inside is provided with the barrel-shaped diameter crossed oil pocket 4 and this minimum diameter crossing oil pocket 4 and be greater than screw 3, this internal diameter crossing oil pocket 4 is reduced to two ends gradually by centre, crossing oil pocket 4 is that middle internal diameter is large, the barrel-shaped inner cavity that two ends internal diameter is little, compare existing cylindrical cavity, the internal surface surface area of this barrel-shaped inner cavity is larger, therefore, it is possible to effectively reduce liquid to the pressure crossing oily joint inner chamber, on the other hand, the arc-shaped inner surface of barrel-shaped inner cavity effectively can cut down the percussion of liquid, greatly improved the working life of oily joint.
In the present embodiment, described oil-through hole 7 is evenly distributed with multiple along crossing oil draining bolt 8 radial direction, thus increase the liquid communication section area entered in oil draining bolt 8, reduce the flow resistance of liquid, on the other hand, this oil-through hole 7 be uniformly distributed circumferentially can make oil draining bolt 8 external force suffered in the course of the work comparatively balance, and avoids oil draining bolt 8 after long-term use concentrated wear to occur, and improves its working life.
The present embodiment transverse and longitudinal, described barrel-shaped joint body sidewall is provided with for jack 2 oily with the mistake of oil pipe 1 grafting, this crosses in oily jack 2 internal thread that can arrange for being fixedly connected with oil pipe 1, and certainly, this internal thread can adopt seal of tube bolt to improve the sealability of link position.
In the present embodiment, the oily jack 2 of described mistake for outside internal diameter be greater than inner side internal diameter cone shape hole 6, the oil pipe 1 be attached thereto can be the flexible pipes such as rubber pipe, this pipeline inserts in the process in cone shape hole 6, oil pipe 1 front end will be subject to the radially inside extruding force in cone shape hole 6 inside, thus the sealability that raising oil pipe 1 is connected with the oily jack 2 of mistake.
In the present embodiment, throttle element has been provided with in described oil-through hole 7, throttle element effectively can control the speed of fluid, pipeline is avoided to occur cavitation, flash distillation, vibration and noise, or oil-through hole 7 can be arranged multiple kink to realize restriction effect, namely oil-through hole 7 comprises the sprue 10 and multiple runner 12 that are interconnected, and sprue 10 one end is communicated with oil channel 11, and the other end is by each runner 12 and cross oily joint inner space.
