The roller bearing 31 for being used to export rotary force on the chassis 331 of housing 33 is arranged in the housing 33 that chimb 332 is constituted, and equably
Between the roller bearing 31 and the chimb 332 and two sides are distributed in be able to rotatably be embedded in the periphery of the roller bearing 31
Several rolling members 32 on face and on the inner peripheral surface of chimb 332, the corresponding spiral on the chimb 332 of the housing 33
Structure 22 is formed with the opening 333 that can be embedded in helical structure 22, and the rolling member 32 is at the opening 333 and institute
The helical structure 22 on shaft 21 is stated to be meshed for driving the roller bearing 31 rotation acting, the chassis 331 and roller bearing 31
It is centrally formed with the axis hole 311 for being used to be inserted into output shaft to connect.
As shown in fig. 7, monosymmetric be formed with of the opening 333 on the chassis 331 can run through the shaft 21
Through hole 334.
As shown in figure 8, monosymmetric be formed with of the opening 333 on the chassis 331 can support the shaft 21
Groove 335.
As shown in Fig. 4, Fig. 5, Fig. 6, the spiral linkage 2 further includes having screw rod bracket 23, the screw rod branch
Frame 23 is Π type structure, and the shaft lever hole 24 that can run through shaft 21 is asymmetrically formed on two side arms of the Π type structure.
As shown in Fig. 9, Figure 14, the rolling member 32 between roller bearing 31 and chimb 332 is by several balls
321 are constituted, or are made of several rollers 322.
As shown in Fig. 9, Figure 10, Figure 12, Figure 13, when the rolling member 32 is made of several balls 321, institute
The ball embedded groove that a circle can be embedded in several balls 321 is circumferentially equally spaced formed on the outer peripheral surface for the roller bearing 31 stated

A kind of screw rod roller bearing dynamic transfer system of the invention is conducted screw rod power by ball (roller), is pushed
Roller bearing rotation, to reach energy transmission.Known, bearing is that the smallest component is lost in machine driving, so in Machine Design
In, it is desirable to reduce the place of frictional force all uses it.The present invention exactly takes full advantage of this characteristic:Roller portion is substantially equivalent
In a bearing core, the push power of screw rod makes the ball (roller) on roller bearing when following rotation before participating in energy transmission, from
The adjustment state of adaptation intervenes power transmitting in the case where frictional force minimum and maximum conductive contacts face.Due to being in always
Under rolling friction state, running efficiency is high, noise is small, generates heat low.Manufacturing cost is a few minutes even tens of conventional worm worm screw
/ mono-, service life really its several times or even tens times.Belong to transmission field and overturn sexual revolution design, thinking surmounts completely
Traditional gear drive theory.
A kind of transmission process of screw rod roller bearing dynamic transfer system of the invention is (by taking ball as an example):Shaft 21 revolves
Turn, to make helical structure 22 that ball 321 be driven to do circulatory motion, due to there is constraint 321, ball on housing 33 and roller bearing 31
The ball insertion slot 312 of shifting and the first guide groove 336 limit (sliding fit), and the ball insertion slot 312 on roller bearing limits
Ball is individually moved, so roller bearing 31 is driven and does circular-rotation.
Destructive testing was done to a kind of screw rod roller bearing dynamic transfer system of the invention:It adjusts spiral linkage and moves
The gap of power output mechanism makes mechanism " critical stall ", is run at high speed with powerful machine driving spiral linkage.Output machine
Housing, roller bearing in structure are all macromolecule materials, and shaft, helical structure are aluminium alloy, and ball is standard rolling bearing ball.20 minutes
After check, the helical structure on shaft, shaft temperature 50-60 degree can not discover abrasion, still maintenance locked rotor condition.It is existing
Conventional worm worm decelerating machine, under this violence damage, heating can be very high, and device will not be locked rotor condition again, is easy to turn
It is dynamic, illustrate that component produces abrasion.Also, ball both is worn in the present invention, only needs transducer set ball, and if worm and gear whirlpool
Wheel damage, speed changer almost without maintenance meaning.One turbine accounts for speed reducer 60-80% cost.There is worm screw affirmative again simultaneously
Abrasion, only changing turbine can accelerate to damage again, a kind of screw rod roller bearing dynamic transfer system absolutely not this respect of the invention
Misgivings.
