Abstract
Disclosed is an open type symmetrically-supported high-speed fluid coupling which comprises a spindle. A shell is arranged outside the spindle, the rear end of the shell is supported through a second tapered roller bearing, the front end of the shell is provided with a close cover which is supported through a first tapered roller bearing, a turbine and an impeller are arranged inside the shell and located on the outer side of the spindle, the impeller is supported through radial ball bearings, the two tapered roller bearings are disposed on the two sides, the radial ball bearings are disposed in the middle, the bearings are all mounted on the spindle, the impeller is connected with the spindle through the radial ball bearings, the turbine is connected with the spindle through a spline and located in the impeller, and a gap is formed between the turbine and the impeller. A transmission medium moves in an open working chamber, and the bearings in the coupling can be lubricated; meanwhile, since only a little of liquid exists in the working chamber of the coupling at first, the coupling is low in starting torque; after normal operation, due to open design, the working speed can reach above 10000r/min.
Description
Technical field
The utility model relates to a kind of high speed fluid coupling, relates in particular to a kind of high speed fluid coupling of open symmetric support.
Background technique
Fluid coupling is that one is widely used and for implementing flexible transmission of torque.As everyone knows, fluid coupling has two and is the radial impeller that is evenly arranged some blades, two impellers are installed in a sealing working cavity the inside that is filled with certain capacity liquid, because liquid is in the body-internal-circulation of sealing active chamber, can only rely on the mode of natural heat dissipation cooling, so need to arrange a melting plug that can melt at specified temp, in the time that coupler reaches the uniform temperature limit, melting plug melts discharge section internal liquid, avoids high temperature injury fluid coupling.This coupler design input speed is lower, can not meet the use of high rotating speed input operating mode.
Summary of the invention
The utility model object is to provide a kind of high speed fluid coupling of open symmetric support, for high speed power is implemented flexible transmission of torque.
The technical solution adopted in the utility model: a kind of high speed fluid coupling of open symmetric support, it comprises main shaft, main shaft is provided with housing outward, housing rear end is supported by the second tapered roller bearing, housing front end is provided with capping, capping is supported by the first tapered roller bearing, in housing, be positioned at main shaft outside and be provided with turbine and pump impeller, pump impeller supports by radial ball bearing, wherein two tapered roller bearings are arranged in both sides, in the middle of radial ball bearing is arranged in, and three is installed on main shaft, pump impeller is connected with main shaft by radial ball bearing, turbine is connected with main shaft by spline, described turbine is positioned at pump impeller, between turbine and pump impeller, form gap, after pump impeller rotates, under the effect of centrifugal force, lubricant oil enters coupler rotor chamber and carries out work, wherein, part Lubricants is known from experience along with discharge in the gap at turbine edge, the liquid of this part discharge is lubricating for the first tapered roller bearing both, again for taking away the heat of part coupler, reach the effect of cooling coupler.
One side of above-mentioned radial ball bearing is provided with spacer ring, and opposite side is provided with locknut.
Above-mentioned spline is involute splines.
Above-mentioned radial ball bearing arranges a pair of.
The technique effect that the utility model is obtained: driving medium of the present utility model moves in an open active chamber, can be lubricated coupler inner bearing, simultaneously because coupler rotor chamber starts to only have little a part of liquid most, so coupler detent torque is lower, after normal work, owing to adopting open by design, more than working speed can reach 10000r/min, special structural design and suitable gap can make coupler reach the combination of ultrahigh rotating speed and transmission efficiency, meet in low detent torque, the flexible output of power under high rotating speed, Transfer Medium can be used as lubricant oil simultaneously and uses, can carry out cooling to bearing, lubricated, they can be in Aero-Space, weaving, generating, extensive use in the industries such as internal-combustion engine.
