Description
Technical field
The utility model relates to retarder technical field, particularly relates to a kind of pin tooth cycloidal reducer.
Background technique
The transmission device that pin tooth cycloidal reducer has been widely used as industrial robot at present is applied.Especially being representative with RV type speed reducer, pin tooth cycloidal reducer is strong with its compact structure, transmission capacity, becomes the most important parts of robot system.Please refer to shown in Fig. 1, RV type pin tooth cycloidal reducer formed primarily of pin wheel housing 1, pin tooth 2, cycloid disc 3, eccentric shaft 4 etc.Eccentric shaft 4 rotarily drives cycloid disc 3, makes cycloid disc 3 do cycloid motion on pin tooth 2 and promote cycloid disc 3 to advance.Can have in theory close to 1/3 number of teeth pin tooth 2 simultaneously with cycloid disc 3 cooperating, that is have so much pin tooth 2 can stressed carrying simultaneously.And in the gear train of involute-type, generally only have one to two teeth to work simultaneously, it can thus be appreciated that, compared to other forms of transmission, owing to there being multiple pin tooth to participate in carrying during work in cyclo drive, therefore its transmission capacity demonstrates unrivaled superiority.
But this multiple tooth requirement carried is also for its manufacturing brings huge difficulty simultaneously.The contact of pin tooth 2 and cycloid disc 3 may because processing, wearing and tearing and error that a variety of causes such as distortion produces and theory differ greatly, so pin tooth 2 process must be very accurate, EE Error Excepted is minimum, otherwise namely the multiple tooth condition carried is destroyed simultaneously, retarder will lose efficacy very soon, even it would be better than other modes; Situation about at this moment occurring can be as seen from Figure 2.
The situation that pin tooth 2 is different from three kinds that cycloid disc 3 contacts has been shown in Fig. 2.The deviation caused due to a variety of causes makes pin tooth 2 only just in time contact with cycloid disc 3 at B place, just in time can promote cycloid disc 3 and advance.And at A place, hypotelorism therebetween.Pin tooth 2 is subject to strong compression, produces very large distortion, advances although pin tooth 2 likely still can promote cycloid disc 3 limpingly, if pin tooth 2 pressure is too large, pin tooth 2 may be crushed, or worn and torn soon, and cycloid disc 3 is like this too.So this situation can not be allowed to.At C place, distance becomes large excessively therebetween, so that pin tooth 2 does not reach cycloid disc 3 at all, this hour hands tooth 2 can not promote cycloid disc 3 and advance.As can be seen here, the Touch error that a variety of causes causes both can make the number of teeth simultaneously carried reduce, and some tooth even also can be made " to be killed " and destroy.
Because pin tooth 2 is solid cylinders, rigidity is very large, and the distortion produced during real work is very little; Changes in contact shown in Fig. 2 is actually very little, is generally only several micron, naked eyes cannot be observed, and the change that figure reflects is actually exaggeration to heavens and is exaggerated.
Participating in carrying to ensure more pin tooth 2 simultaneously, often select the cooperation of interference in actual production, namely make pin tooth 2 in a compressed state, but work when being unlikely to collapse under pressure, but the scope of this work being very limited.Because the ability all too that solid roller can not compress is limited destroyedly.Exactly because may also this too strict requirement, the RV type pin tooth cycloidal reducer that robot is used still can not independently meet the demands so far, mainly still needs to rely on import.
For solving this awkward situation, domestic taked measure at present mainly improves machining accuracy further, draws close to import is original-pack comprehensively.And to improve the main measure of machining accuracy be purchase process equipment that is more senior, mainly import.But fact proved, do so merely and can not fully achieve the goal, and the cost of production brought thus is expensive, also makes people suspect and really can form commercialization in the future, thus reach the ability of competing with external product.
