Description

Technical Field

[0001] The utility model relates to the technical field of speed reduction devices, in particular to a braking mechanism of a speed reducer. Background Technique

[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. The speed reducer is generally used for transmission equipment with low speed and high torque. The power of an electric motor, internal combustion engine, or other high-speed rotating power is reduced by meshing a gear with fewer teeth on the input shaft of the speed reducer with a large gear on the output shaft. Ordinary speed reducers also have several pairs of gears with the same principle to achieve an ideal speed reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio, which plays a role in matching the speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. The speed reducer plays a role in matching the speed and transmitting torque between the prime mover and the working machine or actuator, and is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety of types and models, and different types have different uses. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers, and planetary gear reducers; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers; according to the shape of the gears, they can be divided into cylindrical gear reducers, bevel gear reducers, and bevel-cylindrical gear reducers; according to the layout form of the transmission, they can also be divided into expansion type reducers, split type reducers, and coaxial type reducers.

[0003] The application number is CN202323352426.7, which discloses a braking mechanism for a speed reducer, including a mounting seat and a rotation positioning structure that is movably matched. The mounting seat includes a mounting plate and a positioning plate; the rotation positioning structure includes an L-shaped locking member, a braking operation member, and a stretching and rebounding member. The middle of the L-shaped locking member is rotatably connected to the side of the mounting plate. One side of the middle position of the locking member is in limit cooperation with the mounting plate. The other side of the middle position of the locking member is respectively connected to one end of the braking operation member and the stretching and rebounding member. The other ends of the braking operation member and the stretching and rebounding member are connected to the positioning plate; by pressing down the braking operation member, the L-shaped locking member is driven to move movably with the positioning plate, and at the same time, the stretching and rebounding member is tightened. By lifting the braking operation member, the stretching component automatically lifts the locking member. It has the advantages of simple structure, convenient operation, and good use effect.

[0004] Although the above utility model drives the L-shaped locking part and the positioning plate to move actively by pressing down the brake operating part, and at the same time tightens the stretching and resilient part, by lifting the brake operating part, the stretching component automatically lifts the locking part. It has the advantages of simple structure, convenient operation and good use effect, but the deficiency is that when the device is installed and used, its installation method is relatively unified and traditional, so that it is very easy to loosen during daily use after connection, and then cause damage to the internal machine.

[0005] Therefore, it is necessary to install an anti-loosening installation upper shell component at the top of the device, which can make the installation effect brought by the component very stable when using this device, avoiding the problem that the traditional bolt and nut connection is easy to loosen, so that this device can be used stably and continuously, and reducing the problem of screw loosening.

[0030] The second rotating component 2 includes a connecting rotating rod 201. A first limiting plate 202 is installed at the rear side of the connecting rotating rod 201, and a driven screw rod 203 is installed at the rear side of the first limiting plate 202. When using this device, first, the motor installed on the outside drives the connecting rotating rod 201 inside the second rotating component 2, and then drives the driven screw rod 203 installed at the rear side. After that, it drives the driving runner 101 installed on one side of the driven screw rod 203, so as to achieve the rotating effect. And after the driving runner 101 rotates, it can drive the device installed on the outside.

Then, after rotating and tightening the bifurcated thread piece 3048, release the hand, and push the tension ball 3043 inwards. Since the diameter of the pressing rod 3046 is larger than the through-hole diameter between the bifurcated thread pieces 3048, the fixing effect can be achieved by the pressing rod 3046 at the bottom slightly expanding the bifurcated thread piece 3048. When using this device, first, the motor installed on the outside drives the connecting rotating rod 201 inside the rotating component two 2, which then drives the driven screw rod 203 installed at the back, and then drives the driving wheel 101 installed on one side of the driven screw rod 203, so as to achieve the rotation effect.
