Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a gear reducer which can be quickly installed. Background Art

[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. The reducer needs to be fixed in a specific position because it is used in conjunction with related machinery.

[0003] According to the Chinese patent announcement number: CN220706367U, a gear reducer that can be quickly installed is disclosed. The mounting plate at the bottom of the reducer body is directly placed into the mounting groove by providing a device. After the lower end of the mounting plate contacts the inclined surface, the locking block is pushed into the through hole, and the spring inside the locking block is squeezed. When the locking block corresponds to the locking groove position, the spring pushes the locking block to be stuck in the locking groove, and the mounting plate is pressed against the gasket to make the mounting plate and the mounting groove installed and fastened. When the reducer body needs to be removed, one of the turntables is rotated, the turntable drives the rotating shaft to rotate, and the wire rope drives the locking block to no longer be stuck with the locking groove. At this time, the reducer body can be removed from the base, and the reducer body can be quickly disassembled and assembled when replaced, which saves time, labor and efficiency. After the reducer body in the technical solution is installed, its bottom does not have a corresponding shock-absorbing structure, resulting in the vibration that may be generated by the reducer body during operation. Wear on its own internal structure, thereby affecting the service life of the reducer body, for this reason, we propose a gear reducer that can be quickly installed. Utility Model Content

[0027] Embodiment 1:

[0028] The preferred embodiment of the gear reducer that can be quickly installed provided by the utility model is as follows: Figures 1 to 7 As shown: a gear reducer that can be quickly installed, including a reducer body 1 and a base 3, a mounting plate 2 is fixedly installed at the bottom end of the reducer body 1, a fixing plate 4 is fixedly installed at the bottom end of the base 3, and a mounting mechanism 5 is arranged between the mounting plate 2 and the base 3;

[0029] The mounting mechanism 5 includes a mounting groove 501 and a top plate 502. The mounting groove 501 is provided at the top of the base 3. The mounting plate 2 is inserted into the mounting groove 501. The top plate 502 contacts the bottom end of the mounting plate 2. A top rod 503 is fixedly installed at the bottom end of the top plate 502. A piston chamber 1 507 and a piston chamber 2 510 are provided inside the base 3. The top end of the inner wall of the piston chamber 1 507 of the top rod 503 is connected with the bottom end of the inner wall of the mounting groove 501 and a rod hole 505 is provided. The top rod 503 movably passes through the rod hole 505. A hole pad 506 is fixedly installed on the inner wall of the rod hole 505. The hole pad 506 is in close contact with the outer wall surface of the top rod 503. The outer wall of the top rod 503 is surrounded by a disc spring 504. The disc spring 504 It is fixedly installed between the bottom end of the top plate 502 and the bottom end of the inner wall of the mounting groove 501, a piston plate 508 is fixedly installed at the bottom end of the top rod 503, the piston plate 508 is slidably connected to the inner wall of the piston chamber 1 507, the inner wall of the piston chamber 2 510 is slidably connected to the piston plate 2 511, the top of the piston plate 2 511 is rotatably connected to the rotating rod 512 through a bearing, a contraction groove 513 is provided at the top of the base 3, the rotating rod 512 movably passes through the top end of the inner wall of the piston chamber 2 510 and extends into the contraction groove 513, a clamping plate 514 is fixedly installed at the top of the rotating rod 512, the clamping plate 514 is clamped on the top of the mounting plate 2, and an airway 509 is provided between the piston chamber 1 507 and the piston chamber 2 510.

[0030] Specifically, in the above technical solution, when the reducer body is installed, the mounting plate 2 is inserted into the mounting groove 501, so that the mounting plate 2 presses the top plate 502 downward under the gravity of the reducer body 1, and the top plate 502 compresses the disc spring 504. The top plate 502 drives the piston plate 1 508 to move downward through the push rod 503, so that the piston plate 1 508 compresses the air in the piston chamber 1 507, and the compressed air is transported to the piston chamber 2 510 through the airway 509, so that the piston plate 2 511 in the piston chamber 2 510 moves upward, and the piston plate 2 511 drives the card plate 514 to move upward through the rotating rod 512, so that the card plate 514 extends out of the contraction groove 513, and then the card plate 514 is rotated to make the card plate 514 clamped on the top of the mounting plate 2, so that the mounting plate 2 is limited to complete the installation of the reducer body 1.

By setting the pressure plate 6, the clamping tightness between the clamping plate 514 and the mounting plate 2 can be increased, and the pressure plate 6 has a certain elasticity to avoid hard collision between the mounting plate 2 and the clamping plate 514, thereby ensuring the normal use of the clamping plate 514.

[0037] Furthermore, the shape of the pressing plate 6 is an arch, and the material of the pressing plate 6 is an elastic steel sheet;
