Abstract
The utility model discloses a harmonic drive reducer capable of being used vertically. The harmonic drive reducer capable of being used vertically comprises a rigid gear, a flexible gear, a wave generator, an input shaft and an output shaft, wherein the flexible gear is connected with the input shaft, the wave generator is arranged in the flexible gear and connected with the input shaft, the output shaft is connected with the flexible gear, the input shaft and the output shaft are both vertically arranged, and a bearing used for outputting torque in a rotating mode and fixedly supporting the output shaft is arranged on the output shaft. By means of the harmonic drive reducer capable of being used vertically, the fact that the output shaft is vertically downward is guaranteed, the requirement for vertical output and use of the reducer is met, the application range of the reducer is expanded, and the service life of the reducer is prolonged.
Description
Technical field
The utility model relates to a kind of harmonic wave drive speed reducer, relates in particular to (output shaft vertically downward) harmonic wave drive speed reducer of a kind of vertical use.
Background technique
Harmonic wave drive speed reducer is to rely on flexible part to produce a kind of mechanical driver that the elastic mechanical ripple comes transferring power and motion.Harmonic driving comprises the three basic member: wave-generator, flexbile gear and firm wheel.Three members are fixed arbitrarily one, and all the other two one is that initiatively another is driven, can realize slowing down or speedup (fixed drive ratio), also can be transformed into two inputs, and an output forms differential gearing.Maintain static such as firm wheel, take wave-generator as driving link, flexbile gear is driven member, oval cam in the wave-generator rotates in flexbile gear, just make flexbile gear produce distortion, when the flexbile gear gear teeth of locating at the oval cam major axis two ends of wave-generator and the firm wheel gear teeth had entered engagement, the flexbile gear gear teeth that the minor axis two ends are located were thrown off with the firm wheel gear teeth.For the gear teeth between major axis of wave generator and the minor axis, along being in half engagement that progresses into engagement in the different sections of flexbile gear and firm wheel girth, be called engaging-in; Be in half engagement that withdraws from gradually engagement, be called and nibble out.The continuous rotation of wave-generator, make engaging-in, mesh, nibble out and throw off four kinds of motions and constantly change original separately working staties, this motion is called the side set motion, the side set motion rotates input to become the output of slowing down rotates.
Harmonic wave drive speed reducer have velocity ratio large and scope is wide, precision is high, backlash is little, bearing capacity is large, volume is little, lightweight, transmission efficiency is high, stable drive, noise are little, can to advantages such as confined space transmission campaigns, be widely used in recent years the industries such as robot, Aero-Space, medical apparatus, lathe.
The structural representation of horizontal type level output harmonic wave gearing speed-reducer commonly used as shown in Figure 1, comprise shell 10, just take turns 11, wave-generator 12 and flexbile gear 13, described flexbile gear 13 connects output shaft 15, two bearings 14 are set on the described output shaft 15, the stability that bearing 14 can strengthen output shaft is set, satisfies the requirement of moment output.But existing harmonic wave drive speed reducer is horizontal type level to be used, and can not be applicable to the situation of vertical vertical use, and the using scope restriction is larger.
The model utility content
In view of the defects that prior art exists, the purpose of this utility model provides a kind of harmonic wave drive speed reducer of vertical use.
To achieve these goals, the harmonic wave drive speed reducer of a kind of vertical use that the utility model provides, comprise firm wheel, flexbile gear, wave-generator, input shaft and output shaft, described flexbile gear is connected with described input shaft, described wave-generator is arranged in the described flexbile gear and with described input shaft and is connected, described output shaft is connected with described flexbile gear, wherein, described input shaft and described output shaft are vertical setting, and are provided with on the described output shaft for the bearing that rotates output torque and the described output shaft of fixed support.
As preferably, the described bearing on the described output shaft is two.
As preferably, be provided with oil slinger on the described wave-generator.
As preferably, be provided with dust-proof cover on the described output shaft.
The beneficial effects of the utility model are, guarantee output shaft vertically downward, satisfy the requirement that the vertical output of retarder is used, and have enlarged the Applicable scope of retarder, the working life of having improved retarder.
