Abstract
The utility model discloses a transmission shaft assembly. A transmission shaft 5 is sheathed in and connected with a transmission shaft sleeve 6 and is movably connected with a shaft 1 of a seed sowing device by a universal joint; the universal joint comprises a first universal joint 2 and a second universal joint 7 which are respectively fixed at the two ends of the transmission shaft 5; the second universal joint 7 is internally provided with a connecting block 3; the first universal joint 2 is articulated with the connecting block 3; the shaft 1 of the seed sowing device is a spline transmission shaft; and the connecting block 3 is firmly fixed on the second universal joint 7 by a cylindrical pin 4. Compared with the prior art, the transmission shaft assembly has the beneficial effects that the spline transmission shaft is mainly used for replacing a circular shaft; since the spline transmission shaft is stressed with a whole surface, so that the problem of breakage can be solved, and the phenomenon of seeding omission can be avoided.
Description
Technical field
The utility model relates to a kind of driving-shaft assembly, belongs to the technical field of the shaft coupling of conveying rotary motion.
Background technology
Being used in power transmission shaft in the seeding unit mostly for circular shaft, is bullet type straight pin because circular shaft is connected with the awl tooth, shearing bullet type straight pin in the middle of power transmission shaft repeatedly starts, so bullet type straight pin easy fracture, life-span weak point.In addition,, in the middle of the sowing process, be not easy to realize, cause the generation of broadcast leakage phenomenon often because turning cylinder is inboard at seeding unit.
The utility model content
The purpose of the utility model is to provide a kind of not easy fracture, long driving-shaft assembly of life-span, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of driving-shaft assembly; Power transmission shaft 5 is socketed in the drive-shaft tunnel 6 and through gimbal joints and seeding unit axle 1 and flexibly connects; Said gimbal joints comprises that being provided with contiguous block 3, the first gimbal joints 2 in first gimbal joints 2 that is fixed on the power transmission shaft 5 and second gimbal joints, 7, the second gimbal joints 7 is hinged on this contiguous block 3; It is characterized in that said seeding unit axle 1 is a spline shaft.
Further, said contiguous block 3 is fastened on second gimbal joints 7 through a straight pin 4.
The utility model utilizes spline shaft mainly to replace circular shaft, splined shaft be whole stressed, do not have breakage problem, the broadcast leakage phenomenon does not appear yet.
Description of drawings
Fig. 1 is the structural representation of the utility model driving-shaft assembly.
Embodiment
Through facing the description of embodiment down; To help public understanding the utility model more; But can't be regarded as restriction by the concrete embodiment that the applicant is given to the utility model technical scheme, any definition to parts or technical characterictic change and/or to overall structure do form but not the conversion of essence all should be regarded as the protection domain that technical scheme limited of the utility model.
The utility model preferred embodiment as shown in Figure 1; Driving-shaft assembly comprises power transmission shaft 5 and the seeding unit axle 1 that is connected with this power transmission shaft 5 through gimbal joints; Said seeding unit axle 1 is a spline shaft; The outer cover of power transmission shaft 5 is connected to drive-shaft tunnel 6, and gimbal joints comprises in first gimbal joints 2 that is fixed on the power transmission shaft 5 and second gimbal joints, 7, the second gimbal joints 7 and is provided with contiguous block 3; Contiguous block 3 is fastened on second gimbal joints 7 through standard round pin 4, and first gimbal joints 2 is hinged on this contiguous block 3.In the driving-shaft assembly of present embodiment, utilize spline shaft mainly to replace circular shaft, splined shaft be whole stressed, do not have breakage problem, the broadcast leakage phenomenon does not appear yet.
Certainly; The utility model can also have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
