Abstract

The invention relates to a rolling coupler, which is to solve the problem of power transmission between two shafts with misaligned center lines. The known two-coupler modes are elastic joint, and particularly hole plate pin shaft joint is used in a speed reducer with few teeth difference. The transmitted torque is restrained because the sectional area of the pin roll is limited and only half of a pin shaft participates in the transmission of torque in the torque transmission process. The input shaft of the rolling coupler drives the driving block on a left driving disk and pushes the rolling body on a side of the driving block; then the rolling body pushes a hole, corresponding to the left driving block, on the hole plate to rotate the hole plate. The hole plate pushes a right driving block to rotate through the rolling body in a hole corresponding to the right driving block thereon. In the movement process, all driving blocks take part in the transmission of torque, the sectional area of the driving block is several times that of the pin roll, and therefore, the torque transmitted by the driving blocks is by far larger than that transmitted by the hole plate pin roll structure. The driving block moves in a hole of the hole plate in a rolling friction way under the action of the rolling body.

Description

Rolling coupler

Technical field the present invention relates to a kind of coupling.

Background technique is for solving the not transmission of power between coincident axes of two center lines.Two modes of known connection such as resilient connection, especially usefulness porose disc bearing pin connection in few tooth difference speed reducer.Have only 1/2 bearing pin to participate in the transmission of moment of torsion in the moment of torsion transmittance process because of the restriction of the sectional area of bearing pin in addition, its moment of torsion that transmits is restricted.

Its input shaft of summary of the invention rolling coupler of the present invention drives the driving block on the left drive plate, promotes the rolling element of driving block two sides, and the hole that is promoted on the porose disc by rolling element makes the porose disc rotation again.Porose disc promotes right driving block and makes right drive plate rotation by the rolling element in the hole on it.The effect of rolling element is that the motion of driving block in the porose disc hole carried out in the mode of rolling friction.Driving blocks all in its movement process all participate in transmitting torque, and the driving block sectional area is the moment of torsion that its moment of torsion that is transmitted of several times of bearing pin can transmit much larger than the porose disc bearing pin in addition.

The measure that overcomes the above problems

1, replaces bearing pin with the left and right driving piece

2, place rolling element in the rolling coupler on driving block on the drive plate and the porose disc with it between corresponding aperture.Making the motion between each relative movement part is rolling friction.

The invention has the beneficial effects as follows that using less part to make center line not overlap two between centers transmits more high pulling torque with high efficiency more.

Description of drawings is illustrated the example of executing of the present invention below in conjunction with accompanying drawing

Accompanying drawing Fig. 1 rolling coupler structural drawing,

Fig. 2 is the A-A sectional view of Fig. 1

The embodiment the invention process for example Fig. 1, Fig. 2, shown in

Among the figure: the solid of left drive plate [1], left side cover [2], the kinetoplast baffle plate [3] that rolls left, porose disc [4], right drive plate [5], right rolling element baffle plate [6], right cover [7], left driving block [8], rolling element [9], right driving block [10], left drive plate [1]-be superimposed as by right-hand member large cylinder, small cylinder and supercentral circular hole.Be processed with keyway on its circular hole.A left side is processed with the slotted hole that left driving block [8] can be installed on drive plate [1] right side.(left driving block [8] can be made an integral body with left drive plate [1]).

The solid of left side cover [2]-be superimposed as by outer cylinder and center hole.Its supercentral circular hole is gone up the small cylinder outer cylinder with left drive plate [1] and is cooperated.

The solid of kinetoplast baffle plate [3]-be superimposed as by outer cylinder and center hole rolls left.Its supercentral circular hole is gone up the small cylinder outer cylinder with left drive plate [1] and is cooperated.

The solid of porose disc [4]-be superimposed as by outer cylinder and center hole.The end face of this part is processed with the through hole that can assemble left driving block [8], right driving block [10] and rolling element [9].

The solid of right drive plate [5]-be superimposed as by left end large cylinder, small cylinder and supercentral circular hole.Be processed with keyway on the circular hole.Right drive plate [5] is processed with the slotted hole that right driving block [10] can be installed on the left side.

(right driving block [10] can be made an integral body with right drive plate [5]).

It is right that rolling element baffle plate [6]-kinetoplast baffle plate [3] is identical with rolling left.

Right cover [7]-identical with left side cover [2].

Left side driving block [8]-be the projection of left drive plate [1] right-hand member.

Needle roller in rolling element [9]-its shape such as the needle bearing.

Right driving block [10]-be the projection of right drive plate [1] left end.

Assembling was finished by following six steps

One, left driving block [8] is installed in left drive plate [1] the right-hand member slotted hole.

Two, porose disc [4] is gone up the borehole jack corresponding with left driving block [8] to left driving block [8], in left driving block [8] and porose disc [4] corresponding aperture gap, rolling element [9] is installed.

Three, will roll left kinetoplast baffle plate [3], left side cover [2], successively be installed on left drive plate [1] small cylinder.

Four, right driving block [10] is installed in right drive plate [5] slotted hole; Behind right driving block [10] two side coating butters, rolling element [9] is placed into right driving block [10] two sides

Five, with the right driving block [10] on the 4th step mounted right drive plate [5] and on rolling element [9] be installed in the corresponding with it hole of porose disc [4].

Six, right rolling element baffle plate [6], right cover [7] are installed to the small cylinder of right drive plate [5] right-hand member.

In input shaft was packed left drive plate [1] hole into, the input shaft rotation drove left drive plate [1] rotation by key; Left side driving block [8] rotation.Left side driving block [8] promotes porose disc [4] rotation by its side rolling element [9], porose disc [4] by with the corresponding hole of right driving block [10], promote rolling element [9], under rolling element [9] effect, with the motion of porose disc [4], pass to right drive plate [5] by right driving block [10].By the key of installing in right drive plate [5] circular hole, give output shaft with its transmission of movement.If do not overlap with the output shaft center line with input shaft, then left driving block [8] and right driving block [10] move separately with in their corresponding apertures at porose disc [4], make the left end input shaft pass to the output shaft that does not overlap with its center line around the round Yuncheng of own center line.This structure is as using the moment of torsion that then can increase substantially few tooth difference speed reducer output on few tooth difference speed reducer.
