Description
Technical Field
The utility model relates to a gear drive technical field specifically, relates to a novel gear drive structure and high-speed gear box thereof.
Background
In the field of high-speed gearboxes, in order to ensure smooth transmission, the high-speed gearboxes are often designed into a two-stage transmission structure, the traditional two-stage transmission structure is that gears which are meshed with each other are respectively offset to one side, namely the gears are not positioned at the central position of a fulcrum, so that the radial force borne by bearings at the two fulcrum is not uniform, the flexible deformation of two ends of the gears is inconsistent, and the advance failure of the bearing at one side can be generally caused and the running of the gears is not stable.
Disclosure of Invention
The utility model provides a technical problem lie in overcoming prior art's defect, provide one kind and ensure that high-speed drive is level and smooth stable and can make each axle both ends bearing atress unanimous novel gear drive structure.
The utility model discloses provide one kind simultaneously and be equipped with novel gear drive structure's high-speed gear box.
The purpose of the utility model is realized through the following technical scheme:
the utility model provides a novel gear drive structure, includes low-speed axle and high-speed gear axle, is equipped with the intermediate gear axle between low-speed axle and the high-speed gear axle, and intermediate gear axle middle section part is from taking tooth portion, and the low-speed epaxial install with central gear axle tooth portion meshing driven low-speed gear wheel, intermediate gear axle installs middle gear wheel in tooth portion bilateral symmetry, the high-speed gear axle be equipped with respectively with two middle gear wheel meshing driven meshing tooth portion.
The distance between the installation position of the low-speed gearwheel and the bearing arrangement positions at the two ends of the low-speed shaft is equal, the distance between the two end faces of the tooth part of the intermediate gear shaft and the bearing arrangement positions at the two ends of the intermediate gear shaft is equal, and the distance between the two meshed tooth parts of the high-speed gear shaft and the bearings arranged at the two ends of the high-speed gear shaft is equal.
Preferably, the installation position of the middle large gear is close to the tooth end face of the middle gear shaft.
A high-speed gear box is provided with the novel gear transmission structure.
Compared with the prior art, the utility model discloses following beneficial effect has:
the concept that the gears meshed with each other in the traditional two-stage transmission structure are respectively offset is overturned, the middle gear shaft is provided with the tooth part and the two middle large gears, balanced transmission connection is formed between the low-speed shaft and the high-speed gear shaft, all the gears in the transmission structure are located in the center of the supporting point, the bearing stress at two ends is ensured to be consistent, the flexible deformation at two ends of the gears is ensured to be consistent, the high-speed transmission smoothness of the transmission structure is finally ensured, and the transmission structure can be widely popularized and applied to a high-speed gear box.
Drawings
Fig. 1 is a schematic structural view of the novel gear transmission structure according to embodiment 1.
Detailed Description
The invention will be further described with reference to specific embodiments, wherein the drawings are designed solely for the purpose of illustration and not as a definition of the limits of the patent; for a better understanding of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Example 1
As shown in fig. 1, a high-speed gear box is provided, a novel gear transmission structure is arranged in the high-speed gear box, specifically, the novel gear transmission structure comprises a low-speed shaft 1 and a high-speed gear shaft 2, an intermediate gear shaft 3 is arranged between the low-speed shaft 1 and the high-speed gear shaft 2, the middle section of the intermediate gear shaft 3 is provided with a toothed part, a low-speed gear 4 meshed with the toothed part of the central gear shaft 3 is arranged on the low-speed shaft 1, an intermediate gear 5 is symmetrically arranged on two sides of the toothed part 3, the mounting position of the intermediate gear 5 is close to the end face of the toothed part of the intermediate gear shaft 3, and the high-speed gear shaft 2 is.
The middle big gear is attached to the end face of the tooth part of the middle gear shaft, so that the whole assembly of the transmission structure provides a limiting effect, and the collision between the end faces of the tooth part of the middle big gear and the tooth part of the low-speed big gear can be prevented.
By adopting the related transmission arrangement of the gears and the tooth parts, the offset phenomenon in the traditional two-stage transmission structure can be effectively avoided, and in addition, in order to ensure that the bearing stress at the two ends of each shaft is consistent, the arrangement positions of the gears and the tooth parts need to follow the following principle: the distance between the installation position of the low-speed gearwheel and the bearing arrangement positions at the two ends of the low-speed shaft is equal, the distance between the two end faces of the tooth part of the intermediate gear shaft and the bearing arrangement positions at the two ends of the intermediate gear shaft is equal, and the distance between the two meshed tooth parts of the high-speed gear shaft and the bearings arranged at the two ends of the high-speed gear shaft is equal. Therefore, all gears in the transmission structure are positioned in the center of a fulcrum formed by the bearings, the bearings at two ends of each shaft are stressed uniformly when the transmission structure runs at a high speed, the uniform flexible deformation at two ends of the gears is ensured, and the high-speed transmission process is smooth and stable.
It should be understood that the above-mentioned embodiments are only examples for clearly illustrating the technical solutions of the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
