Description

Technical Field

[0001] The utility model relates to the technical field of reducer gears, in particular to a high-reliability precision reducer gear. Background Art

[0002] The gear of the reducer is one of the mechanical elements that plays a role in reducing speed in the reducer. It realizes transmission, speed regulation and torque amplification through the meshing of gears. Specifically, the gear reducer is usually composed of two or more gears, each of which has a certain number of teeth, which mesh with each other when paired. The size, number of teeth and tooth shape of the gear will affect the speed ratio of the reducer.

[0003] For example, a high-reliability gear reducer with a cycloidal reducer housing disclosed in the publication number CN211117396U has the following beneficial effects: 1. The high-reliability gear reducer with a cycloidal reducer housing is provided with a connecting wall ring and a solid wall ring, which can prevent the internal oil from leaking along the connection gap between them during use by means of a snap connection, and this arrangement has a reinforcing effect on the connection part, has high strength and stability, and has a higher load-bearing capacity. 2. The high-reliability gear reducer with a cycloidal reducer housing is provided with an auxiliary bearing and a co-bearing, which can prevent the outer surface of the output shaft from contacting the parts of the auxiliary bearing and the co-bearing, reduce the friction between them, and play a role in increasing the conversion rate and reducing the power consumption of the rotation rate. A cycloidal wheel and a ring piece are provided, which can convert the rotation speed of the input shaft to achieve the effect of deceleration, and a rotating gear and a meshing gear are provided, which can increase the range of motion of the cycloidal wheel and reduce the frequency of rotation, thereby increasing the frequency of deceleration. 3. The high-reliability gear reducer with a cycloidal reducer housing is provided with a gear wheel and an attached shaft, which can be suitable for several commonly used gear sizes to improve the adaptability of different motor models, and is provided with a pin wheel and a gauge gear wheel, which can make the pin wheel and the internal parts rotate incoaxially, thereby reducing the rotation rate and the internal parts together to play a deceleration effect, so that the deceleration effect is better, and there are rings and balls, which can play a role in reducing the friction when the internal parts contact, and are provided with balls and roller rings, which can help reduce the noise when the machine is operating. In the above patent, when the reducer is damaged, although the operator will quickly take measures to suspend the reducer, due to the inherent physical properties of the reducer, that is, the inertia, the reducer will continue to rotate for a period of time, which will cause serious consequences in some high-precision mechanical systems. For example, in an automated production line, if the output shaft of the reducer continues to rotate after stopping, it may collide with other stationary or moving parts, causing equipment damage, production line interruption and even personal injury.

[0004] Therefore, there is an urgent need for a high-reliability precision reducer gear to solve the above problems. Utility Model Content

[0022] As attached Figure 1 To Attachment Figure 4 As shown: This embodiment provides a high-reliability precision reducer gear, including a gear reducer 1, an output shaft 2 extending from the front side of the gear reducer 1, and a fastening assembly 3 is arranged on the front side of the gear reducer 1.

[0023] The fastening assembly 3 includes a round block 1 31 rotatably connected to the front surface of the gear reducer 1, a movable plate 1 32 is fixedly connected to the surface of the round block 1 31, a linkage plate 33 is rotatably connected to the inner cavity of the movable plate 1 32, an adjusting plate 34 is rotatably connected to the surface of the linkage plate 33, a round block 2 35 is fixedly connected to one side of the adjusting plate 34, one side of the round block 2 35 is rotatably connected to the gear reducer 1, a movable plate 36 is rotatably connected to the inner cavity of the adjusting plate 34, a movable plate 2 37 is rotatably connected to the surface of the movable plate 36, a round block 38 is fixedly connected to one side of the movable plate 2 37, one side of the round block 38 is rotatably connected to the gear reducer 1, and a clamping plate 39 is fixedly connected to the opposite sides of the movable plate 2 37 and the movable plate 1 32.

[0024] A power assembly 4 is arranged on the left side of the front surface of the gear reducer 1. The power assembly 4 includes a rotating plate 41 rotatably connected to the gear reducer 1. An electric telescopic rod 42 is fixedly connected to one side of the rotating plate 41. The output end of the electric telescopic rod 42 extends to the inner cavity of the adjustment plate 34 and is rotatably connected to the adjustment plate 34. The power assembly 4 is used in conjunction with the fastening assembly 3.

[0025] Specifically, the bottoms of both sides of the gear reducer 1 are fixedly connected with mounting plates 5 , and the tops of the mounting plates 5 are penetrated by two fixing bolts 6 .

[0026] In this embodiment, the installation plate 5 and the fixing bolts 6 are used in combination to facilitate the installation and fixing of the gear reducer 1 , thereby facilitating the disassembly of the gear reducer 1 .

[0027] Specifically, a protective shell 7 is fixedly connected to the front surface of the gear reducer 1 , a through hole is opened on one side of the protective shell 7 , and the fastening assembly 3 and the power assembly 4 are both located in the inner cavity of the protective shell 7 .

[0028] In this embodiment, the protective shell 7 and the through hole are used in combination to protect the fastening assembly 3 and the power assembly 4. At the same time, the through hole can prevent the rotation of the output shaft 2 from being affected.

[0029] Specifically, the two clamping plates 39 are fixedly connected to the opposite sides thereof with rubber pads 8 , and one side of the rubber pads 8 is provided with an arc surface.

[0030] In this embodiment, by providing the rubber pad 8 , the rubber pad 8 is used to contact the output shaft 2 instead of the clamping plate 39 , which not only increases the friction between the output shaft 2 , but also helps to protect the clamping plate 39 .

[0031] The working principle and use process of the utility model are as follows: when the gear reducer 1 is damaged, the gear reducer 1 is manually paused and the electric telescopic rod 42 is started. The output end of the electric telescopic rod 42 drives one side of the adjustment plate 34 to move downward. At this time, the adjustment plate 34 rotates with the round block 2 35 as the axis point, and the left side of the adjustment plate 34 moves downward and the right side moves upward. The right side of the adjustment plate 34 drives the movable plate 36 to move upward. When the movable plate 36 moves upward, it drives the movable plate 2 37 to move upward with the round block 3 38 as the axis point. The movable plate 2 37 drives the rubber pad 8 to move toward the output shaft 2 through the transmission of the clamping plate 39. At the same time, the adjustment plate 34 When the left side of the adjusting plate 34 moves downward, the left side of the adjusting plate 34 will drive the linkage plate 33 to move downward, and the linkage plate 33 drives the movable plate 32 to rotate downward with the round block 1 31 as the axis point. When the movable plate 1 32 moves downward, the rubber pad 8 is driven by the clamping plate 39 to move toward the direction of the output shaft 2. At this time, both rubber pads 8 move toward the direction of the output shaft 2. By controlling the contact between the rubber pad 8 and the output shaft 2 and utilizing the friction between the rubber pad 8 and the output shaft 2, the output shaft 2 stops rotating, thereby preventing the gear reducer 1 from driving the output shaft 2 to continue rotating due to the inertia of the internal gear components, thereby effectively protecting the gear from further wear and damage in the shutdown state.

A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
