Description
Technical Field
The utility model belongs to the awl ring field, concretely relates to awl ring that leakproofness is good.
Background
Since the transmission input shaft and output shaft rotate at their respective speeds, there is a "synchronization" problem with shifting gears. Two gears with different rotating speeds are forcibly meshed, so that impact collision is inevitable, and the gears are damaged. Therefore, the gear shifting of the old transmission adopts a two-foot clutch mode, the upshifting is stopped for a moment in the neutral position, and the downshifting is performed by a throttle in the neutral position so as to reduce the rotating speed difference of the gears. However, this operation is complicated and difficult to grasp accurately. The designer therefore creates a "synchronizer" by which the gears to be engaged are brought to a consistent rotational speed for smooth engagement. The intermediate ring and the inner ring of the synchronizer are generally conical ring structures, which are called conical rings for short.
For example, chinese patent No. CN110594416A discloses an elastic sealing device, which includes a first elastic module; the first elastic module is used for elastically fixing the support and keeping the static sealing ring and the rotary sealing ring sealed, and when the static sealing ring is pushed to the rotary sealing ring, the first elastic module can transmit elastic force to the static sealing ring due to the elasticity of the first elastic module; a second elastic module; the elastic auxiliary module as the first elastic module increases the elastic force of the first elastic module so that the rotary seal ring and the stationary seal ring can maintain surface contact with each other in a high-speed rotation state.
The elastic sealing device can set the static ring to be attached to the rotating ring, and prevent the fluid leakage caused by the gap between the rotor and the stator when the rotor rotates at high speed; however, the above-mentioned elastic sealing device still has some disadvantages, such as: firstly, a spring is adopted during sealing, and the spring is easy to generate a biasing force due to the fact that the spring is not a completely axisymmetric article, so that friction is large during sealing; furthermore, the sealing structure described above is complicated.
