Description

Technical Field

[0001] The invention belongs to the technical field of clutches and relates to a clutch device, in particular to a tapered clutch brake device with a braking function. Background Art

[0002] The clutch is widely used. It is not only used in the flywheel housing between the engine and gearbox of the car to temporarily separate and connect the engine and gearbox, but also widely used in processing equipment such as machine tools or lathes. In other words, it is the so-called industrial clutch. This clutch can realize the rotation or stop of the shaft while the motor continues to drive the pulley to rotate, thereby avoiding repeated starting and stopping of the electronics, extending the service life of the motor and reducing energy consumption.

[0003] At present, most of the existing industrial clutches adopt electromagnetic or pneumatic friction type, but both types of clutches have problems. The electromagnetic clutch uses electric current to pass through the magnetic induction coil to generate a magnetic field to attract the clutch plate, so that the driven wheel and the driving wheel are combined. A lot of heat will be generated during the attraction process. Poor heat dissipation or excessively high ambient temperature will cause the electromagnetic coil to overheat and burn out. The pneumatic friction clutch mainly adopts plane friction clutch. The clutch plate is generally made of asbestos or other compound materials pressed together. These materials will generate a lot of heat during the clutch process, causing them to decompose and oxidize, affecting the service life of the clutch, and at the same time generating a lot of It emits harmful gases and has poor environmental protection. Another disadvantage is that it is easy to slip, has poor stability and poor use effect. In addition, most of the existing industrial clutches can only play the role of clutch, with a single function, and cannot achieve braking of the rear axle after separation, so that the shaft cannot be quickly stopped, which greatly reduces the processing efficiency of the processing equipment. At the same time, it also increases the safety risk of the processing equipment. The current clutch and brake are two different accessories, and most manufacturers design them separately. If used in combination, it is inconvenient to use and has poor stability, resulting in a larger size of the entire equipment and a larger footprint, which reduces the peripheral use space and has higher requirements for the site.

[0004] In summary, in order to solve the technical problems existing in the above-mentioned clutch, it is necessary to design a tapered clutch brake device which has a long service life, is safe to use, is environmentally friendly, has good stability, has a compact structure and can realize clutching and braking at the same time. Summary of the invention

[0010] A brake seat, which is fixedly arranged and separated from the transmission seat, and the transmission shaft passes through the brake seat;

[0011] A transmission member is circumferentially fixedly connected to the transmission shaft, the transmission member is located between the transmission seat and the brake seat and is separated from the two, and the transmission member can move axially relative to the transmission shaft;

[0012] When the transmission member moves to the transmission seat, the transmission member and the transmission seat are in contact with each other through a conical surface, and the transmission shaft and the transmission member rotate synchronously with the driving wheel;

[0013] When the transmission member moves to the brake seat, the transmission member and the brake seat are in contact with each other through a conical surface and the transmission shaft stops synchronously with the transmission member.

[0014] In the above-mentioned tapered clutch brake device, the transmission member includes a shaft sleeve and a transmission cover connected to one end of the shaft sleeve, the transmission shaft passes through the shaft sleeve and the transmission cover and is circumferentially fixedly connected to the shaft sleeve, a first tapered hole is provided at one end of the transmission cover adjacent to the transmission seat, a first tapered block is protruding from the transmission seat and the first tapered block can extend into the first tapered hole.

[0015] In the above-mentioned tapered clutch brake device, the other end of the sleeve is movably connected with a brake cover, and a second tapered hole is provided at one end of the brake cover adjacent to the brake seat. A second tapered block is protruding from the brake seat and can extend into the second tapered hole.

[0016] In the above-mentioned tapered clutch brake device, a connecting hole communicating with the second tapered hole is axially penetrated through the brake cover, the connecting hole is threadedly connected to the sleeve, and the rotation direction of the sleeve is the same as the installation direction of the brake cover.

[0017] In the above-mentioned tapered clutch brake device, the sleeve is connected to the transmission shaft by a spline, and the moving distance of the sleeve on the transmission shaft is less than or equal to the length of the keyway on the transmission shaft.

[0018] In the above-mentioned tapered clutch brake device, a drive sleeve is arranged on the outside of the sleeve, and the drive sleeve is located between the transmission cover and the brake cover. The drive sleeve is axially fixed to the sleeve and the sleeve can rotate relative to the drive sleeve. The drive sleeve is connected to cylinders axially fixed on both sides thereof, and the cylinders can drive the drive sleeve and the sleeve to move synchronously.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention can realize the contact between the transmission member and the transmission seat or the brake seat by the axial movement of the transmission member on the transmission shaft. When the transmission member contacts the transmission seat, the transmission shaft and the driving wheel rotate synchronously. When the transmission member contacts the brake seat, the transmission shaft can be quickly stopped. The whole structure can realize both the clutch function and the braking function. The combination of clutch and braking greatly improves the processing efficiency of the processing equipment and also improves the safety performance of the equipment.

[0025] 2. In the whole structure, the clutch function is realized by the contact or separation between the transmission member and the transmission seat through the conical surface, and the braking function is realized by the contact between the transmission member and the brake seat through the conical surface. The conical surface contact greatly increases the contact area between the transmission member and the transmission seat and the brake seat, and increases the friction between the transmission member and the transmission seat or the brake seat, thereby improving the transmission efficiency and braking efficiency of the transmission member, and the transmission member has higher stability during transmission and braking.

[0026] 3. The matching structure of the conical contact enables the transmission part to generate forces in both radial and axial directions when it contacts the transmission seat or the brake seat. Therefore, the closer the transmission part is to the transmission seat or the brake seat, the closer they are to the transmission seat or the brake seat, and the transmission part will not rotate relative to the transmission seat or the brake seat, which greatly improves the reliability of the transmission part during transmission and braking.

[0027] 4. The whole structure is matched with the driving wheel, transmission seat, brake seat, transmission parts and transmission shaft, which realizes the combination of the functions of clutch and brake. It has simple structure, convenient use, good compactness, reduced installation and use space, and smaller site requirements.

[0028] 5. The entire structure is made of metal parts. Due to its simple structure, it is easier to disassemble and assemble. For each component, maintenance and replacement are more flexible. When a component is damaged, only the corresponding component needs to be replaced without replacing the entire component, which greatly reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] The clutch brake device is mainly aimed at improving the clutch or reducer in various processing and manufacturing equipment in existing industrial manufacturing. However, due to its integrated clutch and brake function, the structure is not limited to use in processing or manufacturing equipment, but is also applicable to other fields such as automobiles.

[0036] like Figure 1-Figure 4 As shown, a tapered clutch brake device of the present invention mainly includes a transmission shaft 10, a driving wheel 20, a transmission seat 30, a brake seat 40 and a transmission member 50.

[0037] The transmission shaft 10 is axially extended, and the driving wheel 20 is installed on the transmission shaft 10 through a bearing (not shown in the figure). The bearing makes the driving wheel 20 axially fixed to the transmission shaft 10. At the same time, the driving wheel 20 can rotate relative to the transmission shaft 10. The driving wheel 20 is provided with a belt groove, and the driving wheel 20 can be rotated by connecting the motor with a belt. The transmission seat 30 is circular, which is arranged on one side of the driving wheel 20 and is detachably connected to the driving wheel 20. The transmission seat 30 can rotate synchronously with the driving wheel 20. The transmission shaft 10 passes through the transmission seat 30, and the brake seat 40 is fixedly arranged and separated from the transmission seat 30. That is to say, the brake seat 40 is in a fixed state. When installed and used, a fixed seat (not shown in the figure) can be located at one end of the transmission shaft 10 on the processing table and separated from the transmission shaft 10 and fixedly installed. The brake seat 40 is fixedly installed on the fixed seat. The transmission shaft 10 passes through the brake seat 40, and the transmission member 50 is circumferentially fixedly connected to the transmission shaft 10. That is to say, the transmission member 50 is installed on the transmission shaft 10 and can only move in its axial direction relative to the transmission shaft 10, but the transmission member 50 cannot rotate circumferentially relative to the transmission shaft 10. The transmission member 50 is located between the transmission seat 30 and the brake seat 40 and is separated from the two.

[0038] During operation, the transmission member 50 can move back and forth between the transmission seat 30 and the brake seat 40 relative to the transmission shaft 10. When the transmission member 50 moves toward the transmission seat 30, the transmission member 50 and the transmission seat 30 can contact with each other with a conical surface. At this time, that is, with the conical surface structure matching, the transmission shaft 10 and the transmission member 50 can rotate synchronously with the driving wheel 20, so that the timing driving wheel 20 drives the transmission shaft 10 to rotate. The transmission shaft 10 can be used as a processing axis to process a stationary workpiece, and can also be used as a workpiece mounting axis to drive the workpiece to rotate, so as to realize a stationary tool. The tool is used to process dynamic workpieces. When the transmission member 50 moves toward the brake seat 40, the transmission member 50 and the brake seat 40 are also in contact and matched with the conical surface structure. At this time, since the transmission member 50 is separated from the transmission seat 30, the transmission member 50 and the transmission shaft 10 will gradually stop rotating. After the transmission member 50 contacts the brake seat 40, the transmission member 50 and the transmission shaft 10 quickly stop rotating, thereby achieving a rapid braking effect, and the driving wheel 20 continues to work driven by the motor, ensuring that the motor is always in a working state without repeated start and stop.

[0039] The present invention can realize rapid rotation of the transmission member 50 and the transmission seat 30 and rapid braking of the transmission member 50 and the brake seat 40 through the contact of the conical surface structure, realizing an integrated design of transmission and braking, with more comprehensive functions, simple structure, strong reliability and stability, safe and environmentally friendly use, compact structure, and less restrictive site requirements.

[0040] Based on the above structure, the present invention makes further improvements and refinements thereto.

[0041] like Figure 2-Figure 4As shown, the transmission member 50 includes a sleeve 51 and a transmission cover 52 fixedly connected to one end of the sleeve 51. The sleeve 51 and the transmission cover 52 can be connected in a split manner or in an integrated manner. The transmission shaft 10 passes through the sleeve 51 and the transmission cover 52 and the transmission shaft 10 and the sleeve 51 are fixedly connected circumferentially. The transmission cover 52 and the transmission seat 30 are adjacent to one end and are provided with a first tapered hole 52a from the outside to the inside. The transmission seat 30 is convexly provided with a first tapered block 31. When the sleeve 51 and the transmission cover 52 move synchronously toward the transmission seat 30, the first tapered block 31 can extend into the first tapered hole 52a to achieve the matching of the transmission cover 52 and the conical surface of the rotating seat.

[0042] The matching structure of the conical contact greatly increases the contact area between the transmission cover 52 and the transmission seat 30, and the friction force is greater, so that the closer the transmission cover 52 is to the transmission seat 30, the closer the transmission cover 52 and the transmission seat 30 are. In addition, the special structure of the conical surface makes the transmission seat 30 and the transmission cover 52 generate forces in both radial and axial directions at the same time after contact, and the friction force is further increased, the transmission efficiency is higher, and the transmission cover 52 will not rotate relative to the transmission seat 30, which greatly improves the reliability of the transmission cover 52 during transmission.

[0043] like Figure 3 , Figure 4 As shown, a plurality of mounting holes 32 are provided on the periphery of the transmission seat 30 , and the transmission seat 30 is connected to the driving wheel 20 via bolts (not shown in the figure) through the mounting holes 32 .

[0044] The transmission seat 30 is a wearing part and needs to rub against the transmission cover 52. Compared with other parts, the service life of the transmission cover 52 is slightly shorter. When the transmission seat 30 is severely worn, it needs to be replaced. The bolt connection facilitates the installation and disassembly of the transmission seat 30 and the drive wheel 20, which facilitates the replacement of the transmission seat 30 at a later time.

[0045] like Figure 2-Figure 4 As shown, the other end of the sleeve 51 is movably connected with a brake cover 53, and a second tapered hole 53a is provided from the outside to the inside at one end of the brake cover 53 adjacent to the brake seat 40. A second tapered block 41 is protruding from the brake seat 40. When the brake cover 53, the sleeve 51 and the transmission cover 52 move synchronously toward the brake block, the second tapered block 41 can extend into the second tapered hole 53a, thereby realizing the conical surface matching between the brake cover 53 and the brake seat 40.

[0046] Similarly, the matching structure of the conical contact increases the contact area between the brake hood 53 and the brake seat 40, and the friction force is greater, so that the closer the brake hood 53 is to the brake seat 40, the closer the brake hood 53 is to the brake seat 40. In addition, the special structure of the conical surface allows the brake seat 40 to generate forces in both radial and axial directions after the brake hood 53 contacts the brake seat 40, further increasing the friction force and improving the transmission efficiency. The brake hood 53 will not rotate relative to the brake seat 40, which greatly improves the reliability of the brake seat 40 during braking.

[0047] Of course, in addition to protecting this conical surface matching structure, other clutch or brake structures that realize transmission through conical surface matching and other conical surface matching structures are also within the protection scope of this application.

[0048] In the prior art, common clutches and brakes all use planar contact to achieve clutch and braking functions, but the planar contact structure has a small contact area between the two components. In addition, only axial force is generated during contact, and the friction force is small, resulting in poor clutch and braking effects and low clutch and braking reliability.

[0049] like Figure 3 , Figure 4 As shown, the brake cover 53 is axially penetrated by a connecting hole 53 b communicating with the second tapered hole 53 a , the connecting hole 53 b is threadedly connected to the shaft sleeve 51 , and the rotation direction of the shaft sleeve 51 is the same as the installation direction of the brake cover 53 .

[0050] The brake hood 53 is threadedly connected to the shaft sleeve 51, which realizes the split installation of the brake hood 53 and the shaft sleeve 51, avoids the integral molding of the entire transmission component 50 structure, and facilitates the processing and molding of the entire structure. The brake hood 53 is a consumable part, which is in long-term friction with the brake seat 40 and has a limited service life. The threaded connection improves the disassembly and assembly flexibility of the brake hood 53 and the shaft sleeve 51, facilitates installation and later replacement, and at the same time, the transmission hood 52 and the shaft sleeve 51 can also be replaced in a targeted manner.

[0051] Furthermore, the shaft sleeve 51 is connected to the transmission shaft 10 by a spline, and the moving distance of the shaft sleeve 51 on the transmission shaft 10 is less than or equal to the length of the keyway on the transmission shaft 10 .

[0052] The spline connection can realize the rapid disassembly and assembly of the shaft sleeve 51 and the transmission shaft 10, with high installation efficiency and convenient installation. At the same time, it can ensure the synchronization of the shaft sleeve 51 and the transmission shaft 10. The distance range of movement of the shaft sleeve 51 on the transmission shaft 10 must be less than or equal to the length of the keyway on the transmission shaft 10. In this way, it can be ensured that the shaft sleeve 51 is always matched with the transmission shaft 10, and the matching reliability of the shaft sleeve 51 and the transmission shaft 10 is guaranteed. Of course, the shaft sleeve 51 and the transmission shaft 10 can also be connected in other ways, as long as it can play a circumferential fixing role and can move axially.

[0053] like Figure 1-Figure 4 As shown, a drive sleeve 60 is provided on the outside of the sleeve 51, and the drive sleeve 60 is located between the transmission cover 52 and the brake cover 53. The drive sleeve 60 is axially fixed to the sleeve 51 and the sleeve 51 can rotate relative to the drive sleeve 60. The drive sleeve 60 is connected to the cylinders 70 axially fixed on both sides thereof. The two cylinders 70 can be fixed on a fixed seat or on other fixed components. The two cylinders 70 can synchronously drive the drive sleeve 60 and the sleeve 51 to move synchronously.

[0054] The setting of the drive sleeve 60 provides power for the entire transmission member 50 to move on the transmission shaft 10. The drive sleeve 60 is axially fixedly connected to the shaft sleeve 51 and the shaft sleeve 51 can rotate relative to the drive sleeve 60, so that the drive sleeve 60 and the cylinder 70 do not rotate synchronously with the shaft sleeve 51, but only play a driving role. The two cylinders 70 are symmetrically arranged and connected to the drive sleeve 60 at the same time, which improves the stability and movement accuracy of the entire drive sleeve 60 during movement. As a fixed part, the cylinder 70 can also be fixed on the fixed seat of the processing table, or fixed on other fixed parts.

[0055] Of course, the driving of the driving sleeve 60 can also be achieved by using other driving sources, such as a motor or a cylinder.

[0056] Preferably, Figure 2-Figure 4 As shown, a bearing 61 is disposed in the driving sleeve 60 and the shaft sleeve 51 is located in the bearing 61 , and the bearing 61 is fixedly connected to the shaft sleeve 51 and the driving sleeve 60 , respectively.

[0057] The bearing 61 serves as a transmission component when the shaft sleeve 51 moves. It not only realizes the fixed connection between the drive sleeve 60 and the shaft sleeve 51 in the axial and radial directions, but also prevents the drive sleeve 60 from moving in the axial direction. At the same time, it can realize the rotation of the shaft sleeve 51 relative to the drive sleeve 60, so that the axial drive of the drive sleeve 60 and the circumferential rotation of the shaft sleeve 51 do not interfere with each other. Of course, the connection method between the drive sleeve 60 and the shaft sleeve 51 is not limited to the connection using the bearing 61, and can also be connected through gear transmission or other methods.

[0058] In addition, the threaded connection between the brake cover 53 and the shaft sleeve 51 also facilitates the installation of the bearing 61 and the drive sleeve 60, greatly improving the installation convenience of the entire structure. The entire structure is highly detachable and flexible, which facilitates the flexible replacement of various components after damage.

[0059] like Figure 2-Figure 4 As shown, a retaining ring 62 is protruding from the inner surface of the driving sleeve 60 , and the bearing 61 abuts against the retaining ring 62 .

[0060] The setting of the retaining ring 62 plays a positioning role during installation. In addition, the bearing 61 rests on the retaining ring 62. During the operation of the drive sleeve 60, the relative movement of the bearing 61 and the drive sleeve 60 can be avoided, thereby ensuring the integrity of the bearing 61, the drive sleeve 60, and the bearing 61 sleeve, thereby ensuring that the drive sleeve 60 can normally drive the shaft sleeve 51 to move, thereby ensuring normal transmission and braking.

[0061] like Figure 1-Figure 4 As shown, connecting blocks 63 are protruded from the outer surfaces of both sides of the driving sleeve 60 , and the piston rod of the cylinder 70 axially penetrates the connecting block 63 and is detachably connected to the connecting block 63 .

[0062] The setting of the connecting block 63 facilitates the connection and fixation between the drive sleeve 60 and the cylinder 70, and is easy to disassemble and assemble. At the same time, the connecting block 63 can effectively separate the cylinder 70 from the brake cover 53, the brake seat 40 and other components, and form a safe working distance between the cylinder 70 and the brake cover 53, the brake seat 40 to ensure the normal operation of each component.

[0063] The working principle of the present invention is as follows:

[0064] The structure is installed as a whole in the processing equipment as a part of the processing equipment.

[0065] In the initial state, the brake seat 40 and the cylinder 70 are both fixedly mounted on the processing table, and the transmission member 50 is located between the transmission seat 30 and the brake seat 40 and is separated from the transmission seat 30 and the brake seat 40 respectively.

[0066] The motor of the processing equipment works and drives the driving wheel 20 to rotate idly on the transmission shaft 10 .

[0067] During transmission, the two cylinders 70 work and push the drive sleeve 60 toward the transmission seat 30, and the drive sleeve 60 drives the entire transmission member 50 to approach the transmission seat 30 until the transmission cover 52 is in close contact with the transmission seat 30. At this time, under the cooperation of the transmission cover 52 and the conical surface of the transmission seat 30, the transmission shaft 10 and the transmission member 50 rotate synchronously with the driving wheel 20, thereby realizing the rotation of the workpiece or the rotation of the processing tool.

[0068] During braking, the two cylinders 70 work synchronously and drive the drive sleeve 60 to move in opposite directions. The drive sleeve 60 drives the transmission member 50 to gradually move away from the transmission seat 30 and approach the brake seat 40 until the brake cover 53 is in close contact with the brake seat 40. At this time, since the transmission seat 30 is separated from the transmission cover 52, the transmission member 50 and the transmission shaft 10 stop rotating quickly under the cooperation of the conical surface of the brake cover 53 and the brake seat 40, thereby achieving the purpose of rapid braking.

[0069] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
