The first drive wheel face 74 includes a first drive wheel drive face 132 that is aligned with the intermediate drive wheel first face 66 of the intermediate drive wheel 44.

The transmission wheel overlap of the present invention provides a transmission ratio of the transmission wheel to decelerate or increase the speed, which may be 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:16, 1:17, 1:18, 1:19, 1: 20,1:>20,>20:1,19:1,18:1,17:1,16:1,15:1,14:1,13:1,12:1,11:1,10: 1,9:1,8:1,7:1,6:1,5:1,4:1,3:1,2:1,0.5:1,0.25:1,0.3:1,0.1:1, 0.05:1, 0.25:0.6, and other variations and their incremental ratios. Those skilled in the art will recognize that multiple combinations of multiple sets of drive wheels can be used to achieve a particular pass. The combination and combination of the plurality of sets of drive wheels of the present invention are well adapted to the desired gear ratio.

The combination of drive gear teeth and drive wheel layout allows torque and speed to be varied between input and output values. For example, the combination of the 8-tooth drive wheels 160a, 160b, 160c and the 40-tooth drive wheels 162a, 162b, 162c significantly reduces the gear ratio. For example, the final gear ratio between the 8-tooth drive wheel 160a and the 40-tooth drive wheel 162a is 125:1. This is achieved by the fact that the 8-tooth drive wheel 160a drives the 40-tooth drive wheel 162b at a gear ratio of 5:1, and the 8-tooth drive wheel 160b drives the 40-tooth drive wheel 162c at a gear ratio of 5:1, and the 8-tooth drive wheel 160c is driven. The combination of the 5 tooth drive wheel 162a is driven 5:1, thereby converting the input of 100 rpm to an output of 0.8 rpm (this conversion can also be achieved by converting the input of 0.8 rpm to the output of 100 rpm). For example, the 40-tooth active drive wheel 162 is coupled to the 8-tooth drive wheel 160 to form a 1:5 gear ratio such that the rotational speed of the drive wheel 160 is 5 rpm depending on the rotational speed of the primary drive wheel 162 of 1 rpm. The 20-tooth drive wheel 164 and the 24-tooth drive wheel 166 are coupled to the 40-tooth main drive wheel 162 to form a gear ratio of 1:2 and 1:1.66, respectively, such that the drive wheel 164 and the drive wheel 166 are 1 rpm based on the drive gear 162. The rotational speeds were 2 rpm and 1.66 rpm, respectively. For example, the 8-tooth main drive wheel 160 is coupled to the 40-tooth drive wheel 162 to form a 5:1 gear ratio, with the drive wheel 162 rotating at 1 rpm depending on the main drive wheel 160 speed of 5 rpm. The 8-tooth drive wheel 160 is also coupled to the 20-tooth drive wheel 164 at a gear ratio of 2.5:1, which in turn is coupled to the 24-tooth drive wheel 166 to form a 1.2:1 gear ratio.

Moreover, the present invention includes a transmission that can withstand a significant amount of stress, strain, torque, and friction because the transmission utilizes a spline-type drive wheel profile to distribute forces or loads to more surface areas. The invention includes a splined drive wheel configuration wherein the first drive wheel includes a first set of teeth extending over at least a portion of the surface of the drive wheel. The second transmission wheel is engaged with the first transmission wheel in such a manner as to allow the transmission wheels to increase or decrease relative to each other. In some cases, the drive wheels are curved or tapered to allow for contact and to account for the positioning and rotation of the drive wheels relative to one another. One example includes a bevel gear that meshes with a second drive wheel. However, the drive wheel can be circular, elliptical or other shape if desired. phase Similarly, the second drive wheel can be tapered, tapered, flat or even smooth, and the drive wheel shape can be any desired shape.

Moreover, the teeth or slots of the drive wheel of the present invention can have any size, shape, curvature, bevel, profile, and the like. For example, the grooves between the teeth can be curved, right angled or at any angle. Similarly, the tooth pitch and tooth height can be any desired size. For example, the top of the teeth can be shaped, rounded, angled, smooth, and the like. In addition, the present invention ensures engagement at different angles, and the ring gear and pinion are merely examples. This combination allows the configuration of the drive train or transmission to be between 0 and 90 degrees. The present invention provides, in one embodiment, a drive wheel deceleration or speed increase and utilizes a spline drive wheel transmission of another embodiment to provide increased strength.

The drive wheel 200 includes a first drive wheel face 202 having two or more teeth 204 adapted to create friction between the surfaces. The first drive wheel face 202 has two or more teeth 204 disposed about the exterior of the first drive wheel face 202 and also has a central toothless face 206 in the first drive wheel face 202. The central flank 206 also includes an opening 208 that is sized and shaped to vary depending on the particular application. The first drive wheel face 202 includes a tooth face 210 and a tooth height 212. The tooth width 214 is the width of the tooth surface 210 and is the distance from the first tooth height 212 to the second tooth height 212 and may vary depending on the particular application. The flank 210 and the tooth height 212 provide a frictional contact zone when in contact with another face (not shown). The tooth width 214 and the tooth height 212 may vary depending on the particular application and the particular amount of force applied to the drive wheel 200.

The flank 210 and the tooth height 212 provide a frictional contact zone when in contact with another face (not shown). The tooth width 214 and the tooth height 212 may vary depending on the particular application and the particular magnitude of force applied to the drive wheel 200. In some embodiments, the tooth width 214 can be larger, while in other embodiments, the tooth width 214 can be smaller. Additionally, the first tooth height 212 and the drive wheel base 218 are combined in thickness and included in the drive wheel thickness 216. Gear pitch line 220 and tooth surface 210 form a gear segment taper angle 222. Gear section taper angle 222 is typically the angle of tooth surface 210. If the first tooth height 212 is not perpendicular to the gear pitch line 220, the angle may be different. In some cases, the first tooth height 212 is not perpendicular to the gear pitch line 220, thereby creating an overhang from the first drive wheel surface 202 to the second drive wheel surface 202. Although the flank 210 and the tooth height 212 are straight as shown, other shapes may be employed, including concavities, protrusions, textures, and other surface treatment structures known to those skilled in the art.

The set of gears 808 may include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more gears having different or the same pitch and different gear ratios, and may also include its tooth orientation. The opposite direction of the embedded face gear. As in any of the examples given herein, the gear ratio can be changed to any suitable ratio by varying the pitch, size, position, etc. of the gears and/or teeth, for example, the gear ratio can be 1.5:1, 2.5:1. , 3.5:1, 4.5:1, 5.5:1, 6.5:1, 7.5:1, 8.5:1, 9.5:1, 10.5:1, 1:1, 2:1, 3:1, 4:1, 5 : 1, 6: 1, 7: 1, 8: 1, 9: 1, 10: 1, 11: 1, 12: 1, 13: 1, 14: 1, 15: 1, 20: 1, 25: 1 50:1, etc., the ratio can be used in the reverse direction of the transmission ratio, or 50:1.

While the drive wheels described in the different embodiments give specific gear types, those skilled in the art will recognize that other types of drive wheels can be employed. For example, a spur gear has a predominantly rolling tooth contact where slip occurs during engagement and disengagement. tooth The strips and pinions are basically linearly deformed versions of the spur gears. The inner ring gear includes a cylindrical gear with meshing teeth inside or outside the ring, often used in conjunction with a spur gear. The inner ring gear can be used in the planetary gear structure. The helical gear includes a cylindrical gear having helical teeth. The helical rack gear is linear in shape and cooperates with a rotating helical gear. The herringbone gear can have left-handed and right-handed helical teeth. The face gear is a disk body that cuts a ring of teeth on one side. The gear teeth taper toward the center of the tooth. The worm gear teeth mesh similarly to the helical gears except that they envelop the worm when viewed along the worm axis. The double-enveloped worm gear has a radially varying pitch circle diameter. This increases the number and size of the tooth shear zones. Straight bevel gears have tapered tapered teeth that intersect the same tooth shape. Bevel gears are used to transfer motion between the axes where the centerlines intersect. The angle of intersection is usually 90 degrees, but can be as high as 180 degrees. If the mating gears are the same size and the shafts are placed at 90 degrees to each other, they are called equal-diameter bevel gears. The teeth of the bevel gear can also be cut in a curved manner, resulting in a spiral bevel gear that is smoother and quieter than a straight-cut three-gear. The spiral bevel gear has a helical angle helical tooth. The helical gears (cross helical gears) are helical gears with opposite helix angles that mesh with the axis crossing.

The sleeve joint can be configured to mount a sleeve having a conventional size (eg, 1/4, 1/2, 3/4, 11⁄4, 11⁄2, 13⁄4, 2, 21⁄4, 21⁄2, 23⁄4, 3 inches, etc., ie Corresponds to 0.635, 1.27, 1.905, 2.54, 3.175, 4.445, 5.08, 5.715, 6.35, 6.985, 7.62 cm, etc.). Furthermore, the sleeve joint can be configured as a spline transmission or as a face gear. The textured region of the handle may be formed in the handle portion or on the handle portion and may be constructed of rubber, plastic, metal, polymer, leather, wood, or other suitable material.

As used herein, the term "sleeve" means a conventional sleeve, such as a metric sleeve, a grading sleeve, a long sleeve, a short sleeve, a chrome sleeve or an impact sleeve, etc., in the shape of a hexagonal head, a twelve-corner head, and a flower. Key, Torx star, etc.

In this context, a number of examples can be constructed and adapted for use in all types of wrenches, such as open-end wrenches or open wrenches: one-piece wrenches with U-shaped openings that grip the bolts or The opposite sides of the nut. Such wrenches are typically double-ended with openings at each end having different sizes. The ends are often oriented at an angle of approximately 15 degrees relative to the longitudinal axis of the handle. This allows a wide range of movements in the enclosed space by flipping the wrench; a ring wrench or socket wrench (double-ended staggered): an integral wrench with a closed opening that grips the faces of the bolt or nut. The notches are typically hexagonal or dodecagonal openings for polygonal nuts or bolt heads. The dodecagonal opening is mounted to the fastener at up to twice the angle, with the advantage that the swing is limited. An octagonal wrench is also manufactured for the square nut and bolt head. Ring wrenches are usually double-ended and generally have staggered handles for better access to nuts or bolts.

The ends are usually suitable for bolts of the same size. Tapered nut wrench, pipe wrench or wire wrench: used to clamp the nut at both ends of the pipe. This type of wrench is similar to a socket wrench but does not completely enclose the nut. It has a small opening but is wide enough to allow the wrench to rest on the tube. This allows for maximum contact with the vertical nut, which is usually a softer metal and therefore more susceptible to damage by the wrench; adjustable wrench/wrench, end adjustable wrench, adjustable wrench or adjustable wrench: adjustable ( Usually smooth) jaw wrench open end wrench; adjustable wrench or pneumatic clamp, is an old end adjustable wrench with straight arm handle and smooth jaw; pipe wrench: end adjustable wrench with self-tightening performance and Hard zigzag jaws that only grip soft iron pipes and pipe joints; socket wrenches, universal joints and socket wrenches: hollow cylinders placed on one end of a nut or bolt head, which may include a handle, but usually Used in conjunction with a variety of drive tools, and it typically has hexagonal notches or doweled notches, which may be of the short sleeve type or of the long sleeve type, and may have an embedded universal joint. Commonly used drive handles are: bent (hinge) handles, also known as connecting nut wrenches or soft nut wrenches, often referred to as demolition bars. It is a long non-ratchet bar that is often used for self-locking bolts and nuts. The extra length of the tamper bar allows the same amount of force to be applied to produce a force that is significantly greater than the ratchet wrench that can be applied with a standard length. Ratchet Wrench: Includes a one-way mechanism that allows the sleeve to rotate without removing the nut and bolt, just to bring the wrench back and forth Move back; snap handle, rocker handle or snap crank; screwdriver handle: for sleeves like nut drivers; break bar: it is an extension handle for socket wrenches that adds extra torque for loosening Tighten the dead or stuck fasteners. Torque Wrench: A socket wrench drive tool that measures the amount of rotational force applied to the sleeve, which can be visually represented by a rod or scale, or simply slipped when the set torque is exceeded. Torque wrenches are also classified as measuring tools; Crowfoot socket wrenches: A sleeve designed to mount some of the same drive handles as conventional sleeves, but not cylindrical. Both ends have the same shape as the ends of the wrench, socket wrench or tapered nut wrench. These sleeves are used where space where conventional sleeves cannot be used is limited, and they are in principle used with torque wrenches. Tortus Wrench: Designed similar to a socket wrench, it features a sleeve that is permanently attached to the handle. The sleeve is not interchangeable like a socket wrench, and the sleeve is often rotated around the handle to allow the user to Approach fasteners at different angles. Typically, a torque wrench is part of a double-ended wrench with the wrench head on the opposite side of the socket head. Socket wrench: a tube with a 6-sided sleeve at both ends, which is inserted into two holes in the middle of the tube by a short rod (such as a screw or a T-bar); a tap/impact wrench: a wrench (a wrench) Both the type and the ring wrench type have a closed end to the handle and are designed for use with a hammer. They are often used to remove large nuts and bolts, where the percussion vibration is effective against broken rust paint.

Fire hydrant wrench (valve operating part): This five-corner (five-sided) socket wrench avoids the use of a hexagonal shape for the projection so that the valve is not damaged, and the opposite sides are not parallel. It is almost impossible to open a fire hydrant illegally because the person who wants to open does not have the proper tools.

In addition to the mechanical direction selection mechanism and the separation mechanism, the present invention also employs a magnet mechanism to select a direction, select a gear, engage or disengage one or more gears. Many permanent magnets can be used in the present invention, such as rare earth magnets, ceramic magnets, Alnico magnets, which can be rigid, semi-rigid, and flexible magnets. Flexible magnets are made by doping a flexible material such as chloroprene rubber, ethylene, nitrile, nylon or plastic with magnetic materials such as magnetic iron filings, which will be used in the present invention.

Other examples for use as described above are rare earth magnets, including neodymium iron boron (NdFeB) and samarium cobalt (SmCo) based magnets. There are multiple levels in each category that have a variety of performance and application requirements. Rare earth magnets are available in sintered and bonded form.

The ceramic magnet is a sintered permanent magnet composed of barium ferrite (BaO(Fe ₂ O ₃ ).sub.n) or tin ferrite (SnO(Fe ₂ O ₃ ) _n ), where n is the number of ferrites Variables. Also known as anisotropic hexagonal ferrites, such magnets are useful because of their good resistance to demagnetization and low cost. Although ceramic magnets tend to be hard and brittle and require special processing techniques, these magnets can be used in very precise magnetic retention mechanisms. The anisotropy level is oriented in manufacturing and must be magnetized in a particular direction. Ceramic magnets can also be isotropic, and are generally more practical due to lower cost. Ceramic magnets can be used in many applications and can be pre-packaged or formed for use in the present invention.

A flexible magnet is a magnet composed of a material that is flexible and bonded to a magnetic material. Flexible magnets offer product designers a unique combination of performance at a low cost. A material advantage of flexible and in combination with magnetic compositions is that they can be bent, twisted, crimped, stamped and otherwise machined into almost any shape. There is no loss of magnetic field. Under normal operating conditions, it is desirable to use a flexible magnet because it does not require coating, corrosion resistance, ease of processing, ease of handling, and can be compounded with magnetic materials having high magnetic energy.

More expensive magnet materials such as rare earth metal magnets can be applied to flexible backing materials such as plastic, nylon and polypropylene and will have excellent magnetic strength and flexibility. In addition, the flexible magnet can be made very thin, for example, having a thickness of 1/18 inch or less.

The flexible magnet can also be attached to the magnetic retention mechanism of the present invention by an adhesive suitable for various environments. The type of adhesive used to bond the flexible magnet will depend on the particular application, for example the adhesive may be pressure sensitive. The magnet may be laminated with, for example, a pressure sensitive adhesive. Adhesives useful in the present invention are known to those skilled in the art.

Alnico magnets are mainly composed of AlNiCo and are characterized by excellent temperature stability, high residual flux density and relatively high energy. Alnico magnets are manufactured by casting or sintering. Cast magnets can be manufactured to very high specifications and can have very specific shapes. Sintered AlNiCo magnets are slightly less magnetic than cast magnets but have higher mechanical properties.

Alnico magnets are very resistant to corrosion. Although the AlNiCo magnet is easily demagnetized, this problem can be overcome with a simple operating instruction. The advantage of Alnico magnets is that temperature has little effect on their magnetic properties.

Additionally, the invention can be used in both clockwise and counterclockwise directions. Specifically, the jaws can be used to select clockwise or counterclockwise rotation by selecting the knob to move the jaws to engage the gears and to limit rotation in the opposite direction. In other embodiments, the jaws can be used to separate a gear set to limit motion. Magnets can also be used in place of the jaws to engage a set of gears or split gears or gear sets. Additionally, the magnets and jaws can be used in combination as a redundant system or as an engagement mechanism. In still other embodiments the gear teeth are disposed about the edge of the gear and the jaws are selectively engaged to the teeth.
