Description
Technical field
This utility model relates to a kind of drive mechanism, particularly relates to a kind of gear transmission structure.
Background technology
Existing automatic gear-box is divided into AT and CVT two kinds, wherein AT is actually the manual transmission of fluid drive, wherein gear transmission structure is that gear slides on splined shaft, it is axially engagement, utilize synchromesh gear adjustment, remove and beat tooth, send the drawbacks such as abnormal sound, but due to the construction features of synchromesh gear, it is impossible to transmitting large torque; And CVT changes speed ratio speed change without gear transmission structure, but utilize steel band transmission power, by changing the diameter speed change of drivewheel and follower, steel band easily skids, both are only suitable for small passenger car, so all can not use at the car that even discharge capacity is slightly larger such as medium-sized, heavy, particularly construction machinery gear box mostly adopts hand shift or power shift.
Utility model content
This utility model is in order that overcome the deficiencies in the prior art and provide a kind of simple in construction, it is possible to adjust the rotating speed of two gears and the gear transmission structure that transmission power capacity is strong before gear engages.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of gear transmission structure, including support, spring, the first friction pulley, connecting plate, the second friction pulley, driving gear, driven gear, active friction wheel and driven pulley; Described support is provided with spring; Described lower spring end is provided with rotating first friction pulley; Described first friction pulley is connected by connecting plate and the second friction pulley; Described second friction pulley is spindle rotationally arranged on connecting plate; Described driving gear and the driven gear back side are respectively equipped with active friction wheel and driven pulley; Described first friction pulley and the second friction pulley contact with active friction wheel and driven pulley respectively; Described driving gear Forced rotation is to when being meshed with driven gear, and the first friction pulley and the second friction pulley are compressed respectively by the compression stress of spring.
Preferably, described first friction pulley and the second friction pulley rotate respectively through the first rotating shaft and the second rotating shaft.
Preferably, the material of described first friction pulley, the second friction pulley, active friction wheel and driven pulley is wear-resistant material.
Utilization due to technique scheme, this utility model compared with prior art has the advantage that the gear transmission structure of this utility model scheme, it is simple and practical, with low cost, before driving gear and driven gear engage, the rotating speed of driving gear and driven gear transmission can be mixed up, improve the ability of the transmission power of gear transmission structure, meet the demand of reality, there is higher practicality and promotional value.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of gear transmission structure as illustrated in the accompanying drawings from 1 to 3, including support 1, spring the 2, first friction pulley 3, connecting plate the 4, second friction pulley 5, driving gear 6, driven gear 7, active friction wheel 8 and driven pulley 9; Described support 1 is provided with spring 2; Described spring 2 lower end is provided with rotating first friction pulley 3; Described first friction pulley 3 is connected with the second friction pulley 5 by connecting plate 4; Described second friction pulley 5 is spindle rotationally arranged on connecting plate 4; Described driving gear 6 and driven gear 7 back side are respectively equipped with active friction wheel 8 and driven pulley 9; Described first friction pulley and the second friction pulley contact with active friction wheel 8 and driven pulley 9 respectively; Described driving gear 6 Forced rotation is to when being meshed with driven gear 7, and the first friction pulley 3 and the second friction pulley 5 are compressed respectively by the compression stress of spring 2; Described first friction pulley 3 and the second friction pulley 5 rotate respectively through the first rotating shaft 10 and the second rotating shaft 11; The material of described first friction pulley the 3, second friction pulley 5, active friction wheel 8 and driven pulley 9 is wear-resistant material.
Described in the utility model a kind of gear transmission structure as illustrated in the accompanying drawings from 1 to 3, when it starts transmission, driving gear is engaged toward counterclockwise rotation and driven gear, in rotation process, first the first friction pulley and the second friction pulley contact active friction wheel and the driven pulley at driving gear and the driven gear back side, along with moving closer to of driving gear and driven gear, first friction pulley and the second friction pulley are compressed gradually by the spring pressure on support, until together with driving gear engages each other with driven gear, owing to the gear ratio of each group of friction pulley is identical with the gear ratio of the gear of each group, so it is just that adjustment of rotational speed is good before driving gear and driven gear engage, treat that gear is at a fully engaged to complete, each group of gear simultaneously participates in transmission power with friction pulley, so that the ability of transmission power is greatly enhanced, meet the user demand of reality.
Gear transmission structure of the present utility model, it is simple and practical, with low cost, before driving gear and driven gear engage, the rotating speed of driving gear and driven gear transmission can be mixed up, improve the ability of the transmission power of gear transmission structure, meet the demand of reality, there is higher practicality and promotional value.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all falls within this utility model rights protection scope.
