Description
Technical field
The utility model relates to a kind of retarder, particularly relates to the power input mechanism on a kind of retarder.
Background technique
In power transmission process, usually can be applied to retarder to realize the deceleration transmission to power.Retarder has multiple gearing down form, has planetary gear reducing mechanism, turbine and worm decelerator, reducing reduction gears mechanism.In order to reach deceleration object, sometimes need to arrange multiple reducing gear.The setting of multiple reducing gear then likely can cause the volume of retarder itself comparatively large, then the cost of retarder can be brought high, the shortcoming that structure is not compact.
Disclose a kind of retarder in Chinese invention patent (patent No. 200910306517.2), belong to field of mechanical technique.It solve existing retarder exist transmission efficiency low, install inconvenience etc. technical problem.This retarder, comprise housing, be located in housing for the gearwheel of outputting power, the small gear engaged with gearwheel and one and the joining transmission shaft of power mechanism, the shaft axis of described transmission shaft is vertical with the shaft axis of gearwheel to be arranged and the shaft axis of transmission shaft is positioned at directly over gearwheel, described small gear is engaged on the top of gearwheel, and small gear is connected by steering gear and above-mentioned transmission shaft.The size of the worm type of reduction gearing that this retarder and MOTOVARIO company produce is completely the same, is the most ideal product directly replacing this product, and this retarder also has advantages such as transmission efficiency is high, energy-conserving and environment-protective.
The power input shaft of this retarder is partial to top, when being connected with exterior power mechanism, deflection setting is belonged to owing to rotating input shaft itself, this is unfavorable for retarder transmission in the course of the work and the stability of position, and inconvenience makes the transmission joint of power input shaft and exterior power mechanism.
Summary of the invention
For overcoming above-mentioned defect, the utility model technical issues that need to address are: provide a kind of reducer power input mechanism, this power input mechanism be arranged so that the transmission stability in retarder working procedure is good.
For solveing the technical problem, the technical solution of the utility model: a kind of reducer power input mechanism, be arranged on the outer side surface of reducer shell, comprise input shaft, the reducing gear transmission joint of input shaft and retarder inside, it is characterized in that, reducer shell is provided with driving shaft, and driving shaft and input shaft be arranged in parallel and are positioned at the homonymy of reducer shell, and driving shaft is provided with driving gear, input shaft is provided with driven gear, and driving gear and driven gear are meshed.With this power input mechanism retarder operationally, exterior power is first delivered on driving shaft, is then passed on the reducing gear of retarder inside by active and passive gear and input shaft.Exterior power mechanism is directly fixedly connected with input shaft, but is directly fixedly connected with driving shaft.
Driving shaft is positioned at the center position of reducer shell one outer side surface.Correspondingly, due to the setting of active and passive gear, input shaft is partial to the central position of reducer shell one outer side surface, by the diameter design between active and passive gear, meet the requirement that driving shaft is positioned at described position, and be convenient to arrange more step reduction mechanism in retarder.Driving shaft is positioned at described position, and when driving shaft connects with exterior power mechanism driving, the pto＝power take-off of exterior power mechanism is positioned at the medium position place of retarder short transverse, and retarder transmission stability is in the course of the work good, is convenient to the installation of retarder.
The diameter of driven gear is greater than the diameter of driving gear.Designed by the diametric requirements of described active and passive gear, the reducing gear being passed to retarder inside is gone forward, obtain primary speed-down at power, this is conducive to the abundant deceleration of retarder to power.
Driving gear and driven gear are engaged by helical teeth between the two.Engaged by helical teeth between them, this has adapted to the characteristic of rotating between driving shaft and input shaft well, is convenient to the smooth and easy transmission of power, can reduces the torsion suffered by driving shaft, and is convenient to install driving shaft.
Helical teeth length on driving gear and driven gear is equal.This makes driving gear and driven gear engagement fully, effectively can ensure the stability of both transmission of power.
Block bearing is socketed with respectively in the outer end of driving shaft and input shaft.This power input mechanism is assemblied in after on retarder, outside in power input mechanism on reducing gearbox is snapped with case, set block bearing is assemblied in the undertaking hole set by case internal surface, can provide stable support function for the rotation of driving shaft and input shaft.
The beneficial effects of the utility model are: because the outside at reducer shell is provided with driving shaft in addition, and this driving shaft is used for and extraneous power mechanism direct-drive connects, special consideration is not needed for the position of input shaft on retarder, this makes the setting being convenient to carry out reducing gear in retarder inside, makes the design of retarder to fully take into account slowing effect.By the diameter design of active and passive both gears, and driving shaft is made to be in the medium position place of retarder, so that exterior power mechanism stably can realize the transmission joint between driving shaft.And active and passive gear itself also can realize the deceleration transmission of power by the design of diameter, thus the deceleration making retarder can fully realize power.
Accompanying drawing explanation
Fig. 1 is the using state reference drawing of this reducer power input mechanism.
Embodiment
See in figure, this reducer power input mechanism is the outside being arranged on reducer shell 1, structure comprises input shaft 4, input shaft 4 is arranged on reducer shell 1 one outer side surface rotationally, the inner of input shaft 4 extend into the inside of reducer shell 1, with the reducing gear transmission joint set by reducer shell 1 inside.
Be provided with driving shaft 3 at the center position of reducer shell 1 one outer side surface, driving shaft 3 and both input shafts 4 are positioned at the homonymy of reducer shell 1, and driving shaft 3 and input shaft 4 are between the two every be arrangeding in parallel.
