Description

Technical Field

[0001] This utility model belongs to the field of clutches, and in particular a tooth clutch. Background Technology

[0002] A jaw clutch typically consists of a pair of jaw discs, two end bushings, and a pressure spring. It transmits power through mechanical meshing. The two end bushings connect the driving shaft and the driven shaft, respectively. The jaw discs transmit power by engaging or disengaging the clutch teeth on them. The engagement and disengagement of the driving and driven shafts are achieved by the interlocking or disengaging of the clutch teeth. The sawtooth-shaped clutch teeth have a large axial force when they reverse, pushing the jaw discs away and causing slippage. This type of clutch is commonly used in jaw clutches for one-way applications.

[0003] Compared to roller clutches, jaw clutches can withstand higher torque and speed. Compared to friction clutches, they can achieve faster slippage and unloading, and have a higher slippage frequency. When overloaded, the axial force of the clutch teeth increases accordingly, pushing the jaw clutch plate open and slipping, thus acting as a safety clutch.

[0004] However, during engagement and disengagement of a jaw clutch, the clutch teeth collide with each other under alternating impacts, easily leading to fatigue fracture and fatigue wear. The clutch teeth of the two jaw discs are in surface contact, forming a lower-pair friction pair with high friction. Besides requiring a smooth mating surface, the contact surface of the clutch teeth must also have a suitable pressure angle. A large pressure angle results in a large axial force, reducing power transmission performance; a small pressure angle results in a small axial force, making it difficult to overcome friction, causing slippage difficulties, and reducing disengagement reliability. Power transmission performance and disengagement reliability become contradictory. Furthermore, overload slippage, while providing some overload protection for the components to be protected, can also lead to slippage. While usable, this type of clutch may cause transmission failure and damage to other parts, so the starting load and frequency for overload slippage must be limited. Furthermore, due to the large number of clutch teeth, the spring cannot provide uniform pressure to each tooth, resulting in uneven friction between teeth, leading to uneven load and localized wear. These defects severely limit the operating speed of the jaw clutch, making it incomparable to a roller clutch. Additionally, this type of clutch requires the use of wrenches and pipe wrenches for disassembly, assembly, and adjustment of the spring preload, and the components also need to be equipped with appropriate flat wrenches and pipe wrenches for support, resulting in a large space occupation and complex structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-speed jaw clutch that can balance reliable power transmission and separation, and effectively buffer the impact.

[0006] The technical solution of this utility model is: a high-speed jaw clutch one-way clutch, comprising: an outer sleeve, an L-shaped bushing, a clutch disc, a locking handle, a lower bushing, a jaw clutch disc, and an elastic cylindrical pin. The upper end of the lower bushing is externally threaded and fitted into the lower end of the outer sleeve's threaded hole. The upper end of the lower bushing's stepped hole is fitted into the lower end of the jaw clutch disc. The elastic cylindrical pin passes through the through hole F of the jaw clutch disc and the through hole G of the lower bushing, elastically connecting the two. The upper clutch teeth of the jaw clutch disc are in contact with the lower end of the clutch disc's roller frame. The upper end of the clutch disc is fitted into the inner hole of the L-shaped bushing. The upper side of the large end of the clutch disc is in contact with the lower side of the large end of the L-shaped bushing. The small end of the L-shaped bushing is fitted into the upper inner hole of the outer sleeve. The upper side of the large end of the L-shaped bushing is in contact with the upper step of the outer sleeve. The locking handle is respectively fitted into the threaded hole A of the lower bushing and the threaded hole B of the outer sleeve.

[0007] The inner hole of the outer sleeve is a stepped hole, with a larger inner hole on the lower side and a smaller inner hole on the upper side; the lower end of the lower inner hole is internally threaded, and the upper end is a straight hole, with annularly distributed threaded holes B on the internally threaded section.

[0008] The L-shaped bushing has a small end at the top and a large end at the bottom, with an L-shaped cross-section; it is made of phenolic resin-insulated fabric.

[0009] The clutch disc includes: an upper bushing, a tapered set screw, a compression spring, an open sleeve, a cylindrical set screw, and a roller bracket. The upper side of the roller bracket is fitted inside the open sleeve, which is fitted below the spring seat hole C of the upper bushing. The straight cut of the open sleeve is aligned with the keyway of the roller bracket, and the keyway of the roller bracket is aligned with the threaded hole D of the upper bushing. The threaded end of the cylindrical set screw is fitted into the threaded hole D of the upper bushing, and the cylindrical end is located inside the keyway of the roller bracket. The compression spring is located inside the spring seat hole C, with its lower end close to the upper end of the roller bracket, and the tapered end of the tapered set screw is fitted inside its upper end. The tapered set screw is fitted onto the upper side of the spring seat hole C of the upper bushing.

[0010] The outer edge of the upper bushing is a cylindrical step with a larger lower edge and a smaller upper edge. The upper end of the lower step is provided with spring seat holes C evenly distributed in a ring according to the virtual circle φ. The screw holes D are evenly distributed in a ring along the outer edge of the lower step, and are aligned with the spring seat holes C one by one. Their center lines are collinear with the normal line of the virtual circle φ. The middle hole of the upper bushing is a straight hole with a keyway.

[0011] The spring seat hole C is a through hole, with a screw hole on the upper side and a straight hole on the lower side.

[0012] The virtual circle φ is the virtual circle formed when the spring seat hole C is in operation.

[0013] The open sleeve is a cylindrical sleeve with a straight cut on the side that matches the keyway of the roller frame and the cylindrical end of the cylindrical end set screw; the material is phenolic resin reinforced fabric.

[0014] The roller frame includes: a shift fork, a bolt for reaming holes, a washer, a sleeve, a roller, and a lock nut. The roller is located between the two side plates on the lower side of the shift fork, and the central hole of the roller is aligned with the pin holes E on the two side plates of the shift fork. The washer is located on the inner side of the two side plates of the shift fork and on both sides of the roller, and the central hole of the washer is aligned with the central hole of the roller and the pin holes E on the two side plates of the shift fork. The smooth section of the bolt for reaming holes is sleeved on the central holes of the washer and sleeve, the central hole of the roller, and the pin holes E on the two side plates of the shift fork, and the threaded end is sleeved with a lock nut.

[0015] The upper side of the shift fork is a cylinder, and the side of the cylinder has a straight keyway that matches the cylindrical end of the set screw. The lower side is a rectangular plate, and there are side plates on both sides of the rectangular plate. The upper side of the two side plates is rectangular, and the lower side is semicircle. The center of the semicircle is a pin hole E. The center line of the pin hole E in the left view coincides with the center line of the straight keyway in the left view. The pin holes E on the two side plates are mirror symmetrical.

[0016] The gasket has a centrally located circular structure and is made of phenolic resin-insulated fabric.

[0017] The sleeve is a cylindrical sleeve made of phenolic resin reinforced fabric.

[0018] The outer edge of the roller is a spherical ring, the two sides are flat, and the central hole is a straight hole.

[0019] The locking handle is smaller on the left and larger on the right, with a cone at the left end and an arc at the right end. The smaller section on the left is a screw, and the larger section on the right has a knurled surface.

[0020] The lower bushing is smaller on the upper side and larger on the lower side. The upper side is a stud with a stepped hole at the upper end. The stepped hole at the upper end has annularly distributed through holes G inside. The lower side is a stepped cylinder with annularly distributed threaded holes A outside. The middle hole is a straight hole with a keyway.

[0021] The lower end of the dental insert is flat, the middle section has annularly distributed through holes F, and the upper end has a clutch tooth; one side of the clutch tooth is an inclined step with a pressure angle of β, and the other side is a semi-circular step r, the radius and height of the semi-circular step r are consistent with the outer radius of the roller; the material is glass fiber filled nylon.

[0022] The pressure angle β is 60°–70°.

[0023] In this utility model, the upper stepped hole of the lower bushing is fitted to the lower end of the toothed disc. An elastic cylindrical pin passes through the through hole F of the toothed disc and the through hole G of the lower bushing, elastically connecting the two. The upper external thread of the lower bushing is fitted to the threaded hole at the lower end of the outer sleeve. The upper end of the lower stepped cylindrical pin abuts against the lower end face of the outer sleeve to position the toothed disc. The locking handle screw is fitted to the threaded hole A of the lower bushing. The left end cone presses against the upper external thread of the lower bushing to prevent the thread from loosening.

[0024] The rollers of the lower roller frame of the clutch disc fit against the clutch teeth of the jaw clutch disc, and the friction pair between the two is a rolling pair. The reamed hole of the roller frame is connected to the smooth section of the bolt to the middle hole of the washer and sleeve, the middle hole of the roller, and the pin hole E on both sides of the shift fork. The washer and sleeve are made of phenolic resin reinforced board, which has high strength, good crack resistance, good self-lubrication effect, and good wear resistance, and acts as a sliding bearing. The roller and the jaw clutch disc are made of glass fiber filled nylon, which avoids rigid collisions during clutch engagement. The elastic cylindrical pin connecting the through hole F of the jaw clutch disc and the through hole G of the lower bushing can effectively absorb the impact load generated by the collision in the torque direction. The compression spring of the clutch disc can effectively buffer the impact load generated by the axial collision. By adjusting the tapered end set screw in each spring seat hole of the clutch disc, the compression amount of the compression spring in each spring seat hole can be adjusted to ensure that the preload of each roller frame on the clutch teeth is uniform.

[0025] The center line of the screw hole D coincides with the normal of the virtual circle φ formed by the evenly distributed annular spring seat holes C during operation. The cylindrical end of the set screw fitted into the screw hole D of the upper shaft sleeve is located in the keyway of the roller frame, which restricts the axial rotation and sliding stroke of the roller frame, so that the direction of movement of the roller is tangent to the virtual circle φ.

[0026] An open sleeve isolates the upper bushing and roller frame, while an L-shaped bushing isolates the clutch disc and outer sleeve. Both are made of phenolic resin-reinforced fabric and function as sliding bearings.

[0027] The roller and clutch tooth semicircular step r have the same radius. The nylon material is elastic and can fully fit together when rotating forward, resulting in good load-bearing effect. The rolling pair friction is very small, and the required axial force is small. The height of the semicircular step r can be consistent with the outer radius of the roller. When rotating in reverse, the required axial force of the friction pair is even smaller, and the pressure angle β of the inclined step can also be reduced accordingly.

[0028] When disassembling or assembling the clutch, simply screw the locking handle into the outer sleeve threaded hole B and the lower shaft sleeve threaded hole A respectively; no corresponding wrench or pipe wrench is required, and the parts do not need to be equipped with corresponding flat squares for wrench and pipe wrench support. It occupies little space and has a simple structure.

[0029] Compared with the existing technology, the present invention has the following advantages:

[0030] This invention features high power transmission efficiency. The friction pair between the roller and clutch teeth is a rolling pair. The bolt with the reamed hole has a washer and sleeve embedded between it and the roller frame and shift fork, which act as a sliding bearing. The open sleeve isolates the upper bushing and the roller frame, and the L-shaped bushing isolates the clutch disc and the outer sleeve, also acting as a sliding bearing. During clutch engagement, the friction force is greatly reduced, and the required axial force is small. The height of the semi-circular step r of the clutch teeth can be consistent with the outer radius of the roller. The nylon material is elastic and can fully fit during forward rotation, resulting in good load-bearing capacity and effectively improving power transmission performance.

[0031] This invention features excellent shock absorption. Both the rollers and the jaw clutch are made of glass fiber-filled nylon, preventing rigid impacts during clutch engagement. The elastic cylindrical pin connecting the jaw clutch through hole F and the lower bushing through hole G effectively absorbs the impact load generated by impacts in the torque direction. The clutch disc compression spring effectively buffers the impact load generated by axial impacts. This effectively reduces overload slippage caused by impact loads and improves the overall safety of the system.

[0032] This invention features high operating speed, low friction of the rolling pair during clutch engagement, low required axial force, and significantly reduced wear. The glass fiber-filled nylon material prevents rigid collisions between the rollers and the jaw disc during clutch engagement. The compression spring and elastic cylindrical pin effectively absorb the impact loads generated by torque direction and axial collisions, balancing clutch frequency and separation reliability, and effectively improving operating speed.

[0033] This invention provides good uniformity of load bearing. By adjusting the set screws at the tapered ends of each spring seat hole in the clutch disc, the compression of the springs in each spring seat hole can be adjusted, ensuring that the preload of each roller frame on the clutch teeth is uniform.

[0034] This utility model is highly versatile. It can not only perform unidirectional transmission, but also has the functions of a safety clutch and a flexible coupling, making it a multi-purpose device.

[0035] This invention is easy to maintain. When disassembling or assembling the clutch, simply screw the locking handle into the outer sleeve screw hole B and the lower shaft sleeve screw hole A respectively and turn it. It occupies little space and has a simple structure.

[0036] This utility model has good thread anti-loosening performance. The set handle screw is sleeved into the threaded hole A of the lower bushing, and the left end cone presses against the external thread of the upper end of the lower bushing, which plays a role in preventing thread loosening.
