Abstract
Description
Technical field:
[0001] The utility model relates to a novel centrifugal gear coupler. Background technology:
[0002] Traditional couplers are divided into hydraulic couplers and centrifugal friction couplers. Hydraulic couplers are easy to damage, leak oil, have high cost and complex manufacturing process. Centrifugal friction couplers have simple processing technology, poor use effect, poor bearing capacity and are prone to fire when overloaded. Utility model content:
[0003] The technical problem to be solved by the utility model is to provide a new transmission mode formed by combining an internal meshing gear transmission and an eccentric weight. Under the action of centrifugal force, the eccentric weight on the disc drives the pin shaft and the gear to tilt outward, and the gear no longer rolls along the gear ring, but directly drives the gear ring and the output shaft to rotate and output power. The hydraulic force and friction force are changed into gear centrifugal transmission, and the internal gear planetary transmission structure and the eccentric device are organically combined to achieve efficient transmission, which not only reduces the volume and weight, but also improves the bearing capacity and safety. The manufacturing process is simple, easy to install, easy to maintain, and the manufacturing cost and maintenance cost of the new centrifugal gear coupling are greatly reduced.
[0004] The utility model adopts the following technical solution to solve the above technical problems: the input shaft is fixed at the left middle part of the disc of the novel centrifugal gear coupling, the pin shaft is arranged at the middle part of the disc, the pin shaft is sleeved with gears and eccentric weights, the gears mesh in the gear ring, the eccentric weights tilt outwards under the action of centrifugal force, and the pin shaft and the gears also tilt outwards, at this time the gears no longer roll along the gear ring, but directly rotate with the gear ring and the output shaft.
[0005] The beneficial effects of the utility model are as follows: due to the combination of internal meshing gear transmission and eccentric weights to form a new transmission mode, under the action of centrifugal force, the eccentric weight on the disc drives the pin shaft and the gear to tilt outward, the gear no longer rolls along the ring gear, but directly drives the ring gear and the output shaft to rotate together to output power, the hydraulic force and friction force are changed into centrifugal gear transmission, the internal gear planetary structure and the eccentric device are organically combined, and efficient transmission is realized, which not only reduces the volume and weight, but also improves the bearing capacity and safety.
[0006] 1. The starting current is small, saving 50% compared with rigid connection.
[0007] 2. When in use, no oil is required, saving 30% compared to the hydraulic type.
[0008] 3. When overloaded, it will not generate heat, which is safer than the friction type and can prevent fire.
[0009] 4. When starting, it will not affect the reduction of network voltage, ensuring the normal operation of other equipment.
[0010] 5. During operation, if overload or mechanical failure occurs, it will automatically separate to avoid accidents.
[0011] 6. Easy maintenance, using planetary structure, many meshing teeth, strong bearing capacity, not easy to damage.
[0012] 7. It can be used in all regions, including plateaus and cold areas. Description of the drawings:
[0013] Figure 1 It is a structural schematic diagram of the utility model.
[0014] Figure 2 yes Figure 1 AA view. Specific implementation method:
[0015] Example 1: Figure 1 , Figure 2 As shown, the input shaft 1 is fixed to the left middle part of the disc 2 of the new centrifugal gear coupling, and the pin shaft 5 is set in the middle part of the disc 2. The pin shaft 5 is sleeved with a gear 4 and an eccentric weight 3. The gear 4 meshes in the ring gear 6. Under the action of centrifugal force, the eccentric weight 3 tilts outward, and the pin shaft 5 and the gear 4 also tilt outward. At this time, the gear 4 no longer rolls along the ring gear 6, but directly rotates with the ring gear 6 and the output shaft 7.
[0016] Example 2: Figure 1 , Figure 2 As shown, the output shaft 7 of the novel centrifugal gear coupling is fixedly arranged at the right middle part of the ring gear 6.
[0017] Example 3: Figure 1 , Figure 2 As shown, the novel centrifugal gear coupling can also be externally meshed for transmission, the planetary gears can be evenly distributed in 3, 4, or 6 numbers, and the tooth module and the number of gears can be determined according to the load-bearing capacity.
[0018] Example 4: Figure 1 , Figure 2 As shown, the input shaft 1 and the output shaft 7 of the novel centrifugal gear coupling are movably arranged in the middle of both ends of the housing through bearings, and the input shaft 1 is connected to the driving motor.
[0019] Embodiment 5: The working principle of the utility model is:
[0020] A disc with a pin (made of spring steel) is fixed on the input shaft, and an eccentric weight with a gear is mounted on the pin (bearings are installed in the gear and the eccentric weight). The gear meshes with the ring gear. When the speed is low, the centrifugal force of the eccentric weight is also small, and it cannot overcome the resistance of the output shaft, and can only rotate around the pin; therefore, the gear rolls in the ring gear. When the speed increases (the speed reaches 1200-1500 revolutions per minute), under the action of centrifugal force, the eccentric weight tilts outward, causing the pin to shift outward, and the gear also shifts outward, and the displacement is greater than the meshing clearance between the gear and the ring gear (the meshing clearance is 0.2-0.1 mm). The gear no longer rolls along the ring gear, but directly drives the ring gear and the output 7 to rotate together. This transmission reduces the number of parts, eliminates noise, and improves stability and carrying capacity. When overloaded, the gear rolls in the ring gear again, and the eccentric weight begins to rotate around the pin, so the speed of the output shaft decreases and automatically disengages. This also improves safety. Small size, light weight, good safety, strong bearing capacity, simple manufacturing and assembly process. High transmission efficiency, greatly reducing manufacturing and maintenance costs.
[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
