Description

Technical Field

[0001] This utility model relates to the field of gear technology, and in particular to a transmission gear. Background Technology

[0002] Gears are widely used in equipment transmission structures, such as freshwater pumps. Due to their small size, the main components are the impeller and the motor. When the motor shaft transmits power to the impeller, it needs to be driven by gears. Gears have the characteristics of high transmission efficiency, long service life and compact structure.

[0003] A search revealed that application number CN202020139115.X discloses a transmission gear, including a gear body. The outer wall of the gear body has circumferentially distributed convex teeth. The two sides of the convex teeth are arc-shaped. A groove is provided on the end face of the convex teeth. The groove passes through the top of the arc-shaped ends of the two sides of the convex teeth. A rubber block is placed in the groove. The edge of the rubber block extends beyond the side walls of the convex teeth. The distance by which the rubber block extends beyond the side walls of the convex teeth is between 0.8mm and 1.3mm. This achieves a technical solution of reliable transmission and low vibration.

[0004] With the continuous development of science and technology, many precision instruments are produced. Gear sets and gearboxes are widely used, and various types of gears mesh with each other to control the speed of the equipment. However, adjusting the speed involves changing the number, type, and position of the gears, making the adjustment process cumbersome. Utility Model Content

[0005] This utility model discloses a transmission gear, which aims to solve the technical problem that gear sets and reducers have a wide range of movements, and various types of gears mesh with each other to achieve the effect of controlling the speed of the equipment. When adjusting the speed, the adjustment process is cumbersome due to the need to change the number, type and position of the gears.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A transmission gear includes a gear disk, on both sides of which are integrally provided with pads. The gear disk is disc-shaped, and the circumferential wall of the gear disk is provided with a plurality of teeth, each of which is equidistantly distributed. The gear disk is also connected to an extension drive member.

[0008] Preferably, the extended drive component is specifically configured as a drive component such as a worm gear or a bevel gear.

[0009] Preferably, a slot is provided on one side of the gear plate, and a connecting shaft is fixedly connected to one side of the extension drive member, with the slot and the connecting shaft being configured to cooperate with each other.

[0010] Preferably, the slot, the extension drive, and the connecting shaft are coaxially provided with screw holes, and screws are provided in the screw holes to clamp the gear plate and the extension drive together.

[0011] Preferably, the pad is made of nylon, and the internal slots are also made of nylon.

[0012] Preferably, the thickness of the teeth is 3-5 times the thickness of the pad.

[0013] Preferably, the cross-section of the tooth is trapezoidal, and the two sides of the upper end of the tooth are provided with rounded corners.

[0014] As can be seen from the above, the transmission gear provided by this utility model has the following technical effects.

[0015] Firstly, by rotating the gear plate into the equipment, some space can be left inside the equipment to accommodate the extended drive component. The extended drive component can be a worm gear, bevel gear, or other drive parts. The specific configuration depends on the actual use of the machine. When adjusting the output shaft rotation speed of the gearbox, there is no need to disassemble the gear. Simply replace it with an extended drive component with different transmission characteristics (such as different modules, number of teeth, helix angle, or cone angle) and mesh it with the extended drive component. Similarly, the extended drive component can also be set as a transmission gear of different sizes to meet different equipment needs. This solves the problem mentioned in the background technology that many precision instruments are also produced as a result. Gear sets and gearboxes have a wide range of movements, and various types of gears mesh with each other to achieve the effect of controlling the speed of the equipment. When adjusting the speed, the process of changing the number, model, and position of gears is cumbersome. This simplifies the gear replacement process and saves manpower and resources.

[0016] Secondly, the thickness of the toothed teeth is set to be 3-5 times the thickness of the backing plate. By reasonably adjusting the tooth width, the load is not concentrated at one point when the gear rotates, thus improving the load-bearing capacity of the gear. The teeth are equipped with rounded corners to reduce the contact stress on the tooth surface. The stress is adjusted according to the rotational force to ensure that it is less than the contact stress of the gear plate material itself, preventing pitting and other failure modes on the tooth surface, thus improving the service life of the equipment. In addition, a nylon backing plate is added to give the gear a shock-absorbing effect. Attached Figure Description

[0023] Reference Figures 1 to 3 A transmission gear includes a gear disk 1, with integrated pads 2 on both sides of the gear disk 1. The gear disk 1 is disc-shaped, and its circumferential wall has a plurality of teeth 3, each tooth 3 being equidistantly distributed. The gear disk 1 is also connected to an extension drive component 4, which is specifically configured as a worm gear, bevel gear, or other drive component. A slot 7 is provided on one side of the gear disk 1, and a connecting shaft 5 is fixedly connected to one side of the extension drive component 4. The slot 7 and the connecting shaft 5 are configured to cooperate with each other. A screw hole 8 is coaxially provided on the slot 7, the extension drive component 4, and the connecting shaft 5, and a screw hole 8 is provided on the screw hole 8. The screw 6 clamps the gear plate 1 and the extension drive component 4 together, and rotates the gear plate 1 into the equipment. Some space can be left inside the equipment to accommodate the extension drive component 4. The extension drive component 4 can be a worm gear, bevel gear, or other drive components. The specific setting depends on the actual use of the machine. When adjusting the output shaft rotation speed of the gearbox, it is not necessary to disassemble the gear. Just change the position or model of the adjacent drive component to make it mesh with the extension drive component 4. Similarly, the extension drive component 4 can also be set as a transmission gear of different sizes to meet different needs of the equipment.

[0024] In this embodiment, the pad 2 is made of nylon, and the groove 7 inside it is also made of nylon. The thickness of the tooth 3 is 3-5 times the thickness of the pad 2. By reasonably adjusting the tooth width, the load on the gear is not concentrated at one point when it rotates, thus improving the load-bearing capacity of the gear. The tooth 3 is provided with a rounded corner 301 to reduce the contact stress on the tooth surface. It is adjusted according to the rotational force to ensure that it is less than the contact stress of the material of the gear disk 1 itself, preventing pitting and other failure modes on the tooth surface, improving the service life of the equipment, and the addition of the nylon pad 2 gives the gear a shock-absorbing effect.

[0025] In this embodiment, the cross-section of the tooth 3 is trapezoidal, and rounded corners 301 are provided on both sides of the upper end of the tooth 3.

[0026] Working principle: During use, the gear disk 1 is rotated and installed inside the equipment. Some space is left inside the equipment to accommodate the extension drive component 4. The extension drive component 4 can be a worm gear, bevel gear, or other drive components. The specific setting depends on the actual use of the machine. When adjusting the output shaft rotation speed of the gearbox, there is no need to disassemble the gear. Simply replace it with an extension drive component 4 that has different transmission characteristics (such as different modules, number of teeth, helix angle, or cone angle) and mesh it with the extension drive component 4. Similarly, the extension drive component 4 can also be set as a transmission gear of different sizes to meet different needs of the equipment. This solves the problem mentioned in the background technology that many precision instruments are also produced, gear sets and gearboxes have wide movement, and various types of gears mesh with each other to achieve the effect of controlling the speed of the equipment. When adjusting the speed, the process of changing the number, model, and position of the gears is cumbersome. This simplifies the gear replacement process and saves manpower and resources.

[0027] The thickness of the tooth 3 is 3-5 times that of the pad 2. By reasonably adjusting the tooth width, the load is not concentrated at one point when the gear rotates, thus improving the load-bearing capacity of the gear. The tooth 3 is provided with a rounded corner 301 to reduce the contact stress on the tooth surface. It is adjusted according to the rotational force to ensure that it is less than the contact stress of the material of the gear disk 1 itself, preventing pitting and other failure modes on the tooth surface, and improving the service life of the equipment. In addition, a nylon pad 2 is added to give the gear a shock-absorbing effect.
