Abstract
This application discloses a kind of sealing device of water turbulence retarder, comprise the rotating shaft being provided with rotor and two stators being sheathed on rotating shaft, two stators are positioned at rotor both sides, sealing ring and threaded portion is provided with between rotating shaft and stator, space is provided with between threaded portion and stator, threaded portion is relative to sealing ring closer to rotor, and to rotor can be pushed water in threaded portion.Thus, by arranging sealing ring and threaded portion at stator between rotating shaft, threaded portion is along with axis of rotation, water in retarder is driven to rotor place, water is not easily flowed in bearing, and sealing ring also better prevents water from flowing into bearing, extends the life-span of bearing and retarder.
Description
Technical field
The utility model relates to sealing device, particularly relates to a kind of sealing device of water turbulence retarder.
Background technology
Vehicle with a varied topography, especially in some knobs, cause vehicle be in operation need continuous down hill braking, the major casualties caused because of brake system failure constantly increases.
Facts have proved, retarder solves the malfunctioning preferred plan of motor vehicle braking system.In city vehicle, retarder can extend the life-span of braking system 4 ~ 8 times, effectively reduces vehicle maintenance, cost of business operation.In coach, for steep slope topography, the heat fading that retarder effectively can alleviate the hot generation of hub for vehicle wheel causes braking ability to decline, and the easy layering of tire causes the disadvantage of Earlier cracking, vehicle is travelled safer, reduces the generation of traffic accident.
Traditional water turbulence retarder only arranges sealing ring usually between rotating shaft and stator, but after long-time use, ring wear is easily revealed, and causes water to enter bearing, causes damaging.
Utility model content
The purpose of this utility model is the sealing device being to provide a kind of water turbulence retarder, solves one or more in above-mentioned prior art problem.
According to an aspect of the present utility model, a kind of sealing device of water turbulence retarder is provided, comprise the rotating shaft being provided with rotor and two stators being sheathed on rotating shaft, two stators are positioned at rotor both sides, sealing ring and threaded portion is provided with between rotating shaft and stator, be provided with space between threaded portion and stator, threaded portion is relative to sealing ring closer to rotor, and to rotor can be pushed water in threaded portion.
The utility model by arranging sealing ring and threaded portion at stator between rotating shaft, water in retarder, along with axis of rotation, is driven to rotor place by threaded portion, and water is not easily flowed in bearing, sealing ring also better prevents water from flowing into bearing, extends the life-span of bearing and retarder.
In some embodiments: threaded portion is formed in one in the screw thread of rotating shaft ring side face, and the direction of motion of screw thread is towards rotor.Thus, screw thread can rotate along with rotating shaft, is driven by water to rotor place.
In some embodiments: threaded portion comprises the axle sleeve being sheathed on rotating shaft and the screw thread being located at axle sleeve ring side face.Thus, axle sleeve can protect rotating shaft not easy to wear, and water can be driven to rotor place by the screw thread on axle sleeve, and when screw thread has wearing and tearing, only need change axle sleeve, cost is low, convenient and swift.
In some embodiments: sealing ring is hydraulic sealing ring.Thereby, it is possible to anti-sealing enters bearing, cause damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sealing device of a kind of water turbulence retarder of the utility model.
Embodiment
Illustrate below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of sealing device of water turbulence retarder, comprise the rotating shaft 1 being provided with rotor 11 and two stators 2 being sheathed on rotating shaft 1, rotor 11 key is connected to rotating shaft 1, two stators 2 and is positioned at rotor 11 both sides, sealing ring 3 and threaded portion 4 is provided with between rotating shaft 1 and stator 2, sealing ring 3 is sheathed on rotating shaft 1, and sealing ring 3 is hydraulic sealing ring, is provided with space 5 between threaded portion 4 and stator 2, threaded portion 4 is relative to sealing ring 3 closer to rotor 11, and to rotor 11 can be pushed water in threaded portion 4.
In the present embodiment, threaded portion 4 can also comprise the axle sleeve 41 being sheathed on rotating shaft 1 and the screw thread being shaped in axle sleeve 41 ring side face, and axle sleeve 41 is connected with rotating shaft 1 key, and threaded portion 4 and rotating shaft 1 rotate simultaneously, and the direction of motion of screw thread is towards rotor 11.When retarder is braked, water is filled with between rotor 11 and stator 2, when water will enter between rotating shaft 1 and stator 2, is subject to the resistance of the screw thread on axle sleeve 41, and shipwreck, with near sealing ring 3, also can not damage the bearing of retarder.During space 15 if water bleeds between rotating shaft 1 and stator 2, sealing ring 3 also block water can enter the bearing of retarder.
In addition, threaded portion 4 can also be formed in one in the screw thread of rotating shaft 1 ring side face, and the direction of motion of screw thread is towards rotor 11.
In sum, the utility model by arranging sealing ring and threaded portion at stator between rotating shaft, and threaded portion is along with axis of rotation, water in retarder is driven to rotor place, water is not easily flowed in bearing, and sealing ring also better prevents water from flowing into bearing, extends the life-span of bearing and retarder.
The above is only a kind of execution mode of the present utility model; it should be pointed out that to those skilled in the art, under the prerequisite not departing from the utility model creation design; can also make some similar distortion and improvement, these also should be considered as within protection range of the present utility model.
