Abstract

PURPOSE: An apparatus for changing a rotational motion and a linear reciprocating motion into the reciprocating motion and the rotational motion is provided to accurately transfer power and to effectively use energy. CONSTITUTION: An 180degrees spur gear is installed at one side of the top of two pinion cam gears. A timing belt(31) is installed at the bottom of the two pinion cam gears. A ball bush(19) is built in the center of a cylinder rod(15). A male screw of one end of the cylinder rod is connected to a female screw of both cross sections of a double-sided rack gear(25). A guide part is fixed and installed on the top of a body lower plate(21). The two pinion cam gears are rotated by the timing belt and the double-sided rack gear reciprocates when torque is transferred to a driving shaft.

Description

A device that converts rotary and linear reciprocating motions into linear reciprocating and rotary motions. {A EQUIPMENT FOR POWER TRANSMISSION}

In general, efficient transformation of the direction of force is necessary in the overall field of industry.

In the case of automobiles, it is a representative case of converting linear reciprocating motion into rotational motion, and a conveying device of a cutting machine such as lathe and milling is a representative case of converting rotational motion into linear reciprocating motion.

However, the above devices cannot be converted efficiently because the power and speed before conversion are significantly different from the power and speed after conversion, and the efficiency thereof is low, so the present invention provides an efficient power converter. There is a purpose.

The present invention is a device using a cam-shaped gear of the half (cam-type pinion gear installed only the range of tooth teeth 180 °) and a rack gear of both sides and a guide device for maintaining a straight reciprocating motion through the ball bush, timing belt, etc. By using the power transmission device using the technology using the parts through the kinematic analysis can be called the background technology.

As described above, in the power converter, the power must be converted to the same force and speed so that it is efficient.

The present invention uses a cam-shaped gear of one half (a cam-type pinion gear having a gear tooth only 180 ° range) and one double-sided rack gear. If there is a backlash that occurs, the two pinion gears will collide, so in the transmission of the rotational motion, it is necessary to transmit the correct power.

Therefore, the present invention enables accurate transmission of power by using a timing belt and a gear.

As described above, since before and after the power transmission is converted into the same force and speed, the efficiency is high, so that the energy is efficiently used, and thus, the present invention may be a necessary invention at the present time of serious energy shortage.

Figure 1: Planar cross section of the present invention
2 is a right cross-sectional view of the present invention

The configuration of the present invention will be described in detail with reference to FIGS. 1 and 2 as follows.

First, in order to effectively explain the present invention, the case in which the air cylinders 13 are installed on both sides and the rotational force is converted into a linear reciprocating motion will be described.

A ball bush 19 is built in the middle of the cylinder rod 15, and the housing 19 in which the fixing body 27 is installed in one end is fitted to the cylinder rod 15, thereby providing two air cylinders 13 installed. Prepare.

Then, the check valve 11 is provided in the inlet port of the air cylinder 13, and the electromagnetic valve 37 and the check valve 29 are firmly installed in the outlet port through pipe joints.

Subsequently, the cylinder rod 15 is attached to both end surfaces of the double-sided rack gear 25 in which the rack gears are provided on both sides of the circular rod.

On the other hand, the 180 ° spur gear is installed in the upper portion, the rest is installed as a cylindrical portion having a smaller radius than the tooth root circle of the gear, the lower portion is a timing belt gear is installed, the center portion is penetrated in a circular shape so that the key 23 groove is The pinion cam gears 35 and 36 provided are prepared, respectively.

On the other hand, the drive shaft 33 is provided with ball bearings 39 at two places at predetermined intervals on the upper surface of the body upper plate 21, and the pinion cam gears 35 and 36 prepared as the key 23 are fixed. ) And the driven shaft 35 are installed through the respective ball bearings 39, and the timing belt 31 is installed in two timing gears.

At this time, the gear part center of the pinion cam gear 35 installed on the drive shaft 33 and the gear part center of the pinion cam gear 36 installed on the driven shaft 34 must be exactly coincident, and the directions in which the gear parts are located are also the same. It must be direction.

Subsequently, the prepared double-sided rack gear 25 is positioned in the middle of the drive shaft 33 and the driven shaft 34, and the fixed body 27 and the body lower plate 21 are firmly installed.

Subsequently, after installing the body upper plate 22 symmetrically installed with the body lower plate 21 to coincide with the ball bearing center, the circular rod 38 is installed between the body upper plate 22 and the body lower plate 21. After the screw joint, if firmly fixed installation is completed the configuration of the present invention.

Referring to the operation of the present invention in detail on the basis of the accompanying drawings as follows.

1 and 2, when the rotational force is transmitted to the drive shaft 33, the two pinion cam gears 35, 36 are rotated simultaneously by the timing belt 31, the double-sided rack gear 25 Let reciprocate).

On the contrary, when the double-sided rack gear 25 is linearly reciprocated, the drive shaft 33 and the driven shaft 35 are rotated.

At this time, the strongest force is required near the top dead center where the highest pressure of the air cylinder is formed. When compressing as a crank mechanism, the weakest force is generated, but it is not efficient. Since the speed is constant, high compression efficiency can be obtained.

For reference, the electronic valve 37 is for adjusting an initial load when using energy such as wind power.

On the contrary, when the present invention combines the two devices on a coaxial line, a strong rotational force can be obtained.

What has been described above is just one embodiment for carrying out the present invention of the apparatus for converting the rotational movement and the linear reciprocating motion into a linear reciprocating motion and the rotational movement, the present invention is not limited to the above embodiments, Various modifications can be made by those skilled in the art without departing from the spirit of the invention as claimed in the claims.
