Abstract

PURPOSE:To provide a small-sized rotation-reciprocation converter having large load capacity by setting a difference of phase differences between adjacent grooves in such a manner as to keep a difference more than a value corresponding to a groove width, and lessening the maximum phase difference and its deviation. CONSTITUTION:Each difference ¦alpha2-alpha1¦, ¦alpha3-alpha2¦... ¦alpha1-alpham¦ of phase differences alpha1, alpha2...alpham between adjacent grooves of phase differences alpha1, alpha2...alpha3 between guide grooves 2, 2' is set in such a manner as to keep a difference more than a value corresponding to a groove width, and the maximum phase difference and its deviation are lessened. Thus, the grooves 2, 2' are kept from overlapping each other at an intersection portion, and the smoothness and counterbalance in giving and receiving power between a cylindrical surface 1 and a piston 5 can be enhanced, which can provide a small-sized rotation-reciprocation converter having large load capacity.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for mutually converting rotational motion and reciprocating motion.

There are many questions about changing rotational speed into 4119 motion, or conversely, changing reciprocating motion into rotary motion, and crank mechanisms, rotating swash plates, rocking plates, and many IIN sides have been used since ancient times. However, the conversion mechanism is not necessarily ideal in terms of shape constraints, efficiency, balance, etc. 3. In various compressors, bonnets, internal combustion engines, Stirling engines, etc. 4. Negative R7i rll: There is a force, the contact pressure is small on the 87 part, the force is balanced, but the rotation angle and the relationship between (,7) -
2 - A rotation/1) double-acting converter with a high degree of freedom is desired, but there is no one that fully satisfies these requirements (,!jmi1).
I'm not alone.

The present invention is a rotary/reciprocating conversion device that is small in size, has a large loading capacity, and has a degree of freedom and balance in the conversion relationship.
To provide equipment that can be used for each scale FF compressor, pump, internal combustion engine, Stirling engine, and other mechanisms [1]
It's spot on.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 41 of the piston that cums
Transmission of power and motion in the return motion will be explained.

The cylindrical surface 1 has guide grooves 2 and 2' whose phase is the circumferential angle.
is provided in a sinusoidal waveform with two periods per rotation, and is configured so that it can rotate while being restrained from moving in the axial direction by thrust bearings 4 and 4' that support the shaft 3. The outer periphery of the piston 5 is provided with screws 9 and 9' for controlling the rotation of the screws 1 and 9 with respect to the cylinder 8. The movable grooves 10 and 10' are stepped. The rotation of the shaft 3 (2, depending on the rotation of the screw (~ 5 per rotation of the rotating surface) produces 11 double movements at a ratio of II 4u. The guide groove rotates the cylindrical surface +r≦
As shown in Fig. 13, four intersections occur per two periods of one rotation, but the phase of each guide groove is set to (1/2).

In addition, J shown in Figure 4+1, the rolling ball 13 is placed on the roller 6.
6', 7, and 7' can be used as substitute moss, and the guide groove 4-2l) can also be shaped to suit this. Roughly, in order to reduce the slippage on the rollers, [1-La6
6', 7, and 7' as shown in FIG. 4C: The portion 13' in contact with the sea urchin guide groove 2G can also be shaped into a circle whose height covers the radius of the cylindrical surface.

In the case of two guide grooves in this device, a phase difference equivalent to 1゛ greater than the full width is given to ((-α1), and π/(m ・
It is easy to prevent the deviation from 0) from becoming too large. (α2-α1) is equivalent to full width -1-
As long as , the two pairs of rollers will never enter the intersection of the guide grooves at the same time, and as long as (α2-αI) is not extremely large, balance can always be maintained.

In the case of m-4, as shown in FIG. 5 (11), there are 12 intersections in one period, and the degree of freedom in selection is reduced.
