Abstract

A roller-disk type stepless speed variator features that multiple rollers take part in transferring greater torque, and it has zero, forward rotation and reverse rotation outputs. Its advantages are high speed rate and high drive rate.

Description

Roller square position stepless speed variator

The invention belongs to a kind of mechanical stepless transmission, specifically, belong to a kind of roller square position stepless speed variator.

Existing technology is the pattern of single roller, and the moment of torsion that can transmit is less.

The objective of the invention is In view of the foregoing to provide a kind of roller square position stepless speed variator that can transmit than high pulling torque.

In order to achieve the above object, thinking of the present invention is the quantity that increases the roller that participates in transmitting torque.

The invention of claim 1 is a kind of roller square position stepless speed variator, and it comprises: can output shaft and the intermediate gear of free rotation ground supporting on housing; The location is connected in the pressurization disk on the output shaft; The output disc that can free rotation ground supporting on output shaft and by end cam, engages with pressurization disk; Spring between output disc and pressurization disk; Locate the input disc that is linked together with intermediate gear; The roller that contacts simultaneously and can freely rotate and move along self gyration center line with input disc and output disc; It is characterized in that: around around aforesaid output shaft, be uniform-distribution with three cover or quadruplet input disc, roller and intermediate gears, have and freely to rotate and central gear that the while is meshed with all intermediate gear.According to this formation, have three or four rolling participation transmitting torque simultaneously, on the torsion theory that is transmitted three times or four times of single roller.

The invention of claim 2 is, require in the 1 described invention formation at aforesaid right, additional following characteristics: along the centerline direction of aforesaid output shaft, with the symmetrical position of aforesaid input disc on all have the input disc that same and aforementioned intermediate gear location is linked together, with the symmetrical position of aforesaid roller on all have same roller, with the symmetrical position of aforesaid output disc on have a location and be connected in output disc on the aforesaid output shaft.According to this formation, have six or eight rollers participation transmitting torques simultaneously, on the torsion theory that is transmitted six times or octuple of single roller.

Fig. 1, Fig. 2 and Fig. 3 are the plan views of structural principle sketch of the present invention.

Fig. 4 is the left side view of Fig. 1 and Fig. 3.

Fig. 1 with reference to the accompanying drawings, Fig. 2, Fig. 3 and Fig. 4 are illustrated structure of the present invention and principle.

At first come with reference to the Fig. 1 in the accompanying drawing, Fig. 2 and Fig. 4, output shaft 1, input shaft 7 and intermediate gear 10 can free rotation ground supporting on housing 2, pressurization disk 4 location are connected on the output shaft 1, output disc 5 can engage with pressurization disk 4 on output shaft 1 and by end cam by free rotation ground supporting, between output disc 5 and pressurization disk 4, be provided with spring 3, input disc 8 is linked together with intermediate gear 10 location, roller 6 contacts with input disc 8 and output disc 5 simultaneously and can freely rotate and move along self gyration center line, input gear 9 location are connected on the input shaft 7 and with intermediate gear 10 and are meshed, around around output shaft 1, be uniform-distribution with three cover input discs 8, roller 6 and intermediate gear 10, central gear 11 can freely rotate and be meshed with all intermediate gear 10 simultaneously.Need to prove in addition, also can be at even distribution quadruplet input disc 8, roller 6 and intermediate gear 10 on every side around output shaft 1.

Rotation is from input shaft 7 inputs, be delivered on the intermediate gear 10 that is meshed with it by input gear 9 then, and then be delivered on two other intermediate gear 10 by central gear 11, be delivered on the output disc 5 through input disc 8 and roller 6 again, output disc 5 is delivered to rotation on the pressurization disk 4 through end cam, finally will rotate output by output shaft 1.When all rollers 6 when separately gyration center line locking moves, continuous variation will take place in the position of the point of contact between roller 6 and output disc 5, the input disc 8, make velocity ratio take place to change continuously, thereby the rotating speed that makes output shaft 1 produces stepless variation, output shaft 1 can produce zero rotating speed and forward and backward output, and has bigger speed increasing ratio, therefore has bigger gear range, owing to have three or four rolling 6 participation transmitting torques simultaneously, so can transfer larger torque, on vehicle, have broad application prospects.Need to prove in addition, as shown in Figure 2, also can remove input shaft 7 and input gear 9, will rotate from central gear 11 inputs.

And then come with reference to the Fig. 3 in the accompanying drawing and Fig. 4, centerline direction along output shaft 1, with the symmetrical position of input disc 8 on all have the same input disc 8 that is linked together with intermediate gear 10 location, with the symmetrical position of roller 6 on all have same roller 6, with the symmetrical position of output disc 5 on have a location and be connected in output disc 12 on the output shaft 1.Need to prove both to have had six input discs 8, six rollers 6 and three intermediate gears 10 in addition, also can have eight input discs 8, eight rollers 6 and four intermediate gears 10.

Rotation is from input shaft 7 inputs, be delivered on the intermediate gear 10 that is meshed with it by input gear 9 then, and then be delivered on two other intermediate gear 10 by central gear 11, process input disc 8 and roller 6 will rotate and be delivered to respectively on output disc 5 and the output disc 12 again, output disc 5 is delivered to rotation on the pressurization disk 4 through end cam, and the rotation of output disc 12 and pressurization disk 4 is finally by output shaft 1 output.When all rollers 6 when separately gyration center line locking moves, roller 6 and output disc 5, input disc 8, continuous variation will take place in the position of the point of contact between the output disc 12, make velocity ratio take place to change continuously, thereby the rotating speed that makes output shaft 1 produces stepless variation, output shaft 1 can produce zero rotating speed and just, counter-rotating output, and has bigger speed increasing ratio, therefore has bigger gear range, owing to have six or eight rollers 6 participation transmitting torques simultaneously, so can transmit bigger moment of torsion, on vehicle, have more wide application prospect.
