Summary of the invention
The utility model provides a kind of assembly structure of planetary type gear transmission unit, and its object is to solve the problem that is difficult to simultaneously tooth be engaged between planet wheel and sun gear, planet wheel and ring gear in prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of assembly structure of planetary type gear transmission unit, comprise the planet carrier, sun gear, casing, internal tooth casing and the ring gear that are provided with planet wheel, described internal tooth casing and ring gear are located in casing, internal tooth casing is corresponding to described sun gear setting, and ring gear is corresponding to described planet wheel setting; Its innovation is: described sun gear top is provided with suspension rod, on planet carrier, offers pilot hole corresponding to this suspension rod, and suspension rod is located in pilot hole, and one end of suspension rod is flexibly connected with sun gear, and the other end stretches out outside planet carrier.
Related content in technique scheme is explained as follows:
1, in such scheme, one end of described suspension rod offers outside thread, and the top of described sun gear offers tapped hole, between one end of suspension rod and sun gear, is threaded connection.
2, in such scheme, one end and a nut that described suspension rod stretches out planet carrier are threaded connection, and are provided with a pressing plate between nut and planet carrier, and this pressing plate is set on suspension rod, and the external diameter of pressing plate is greater than the aperture of described pilot hole.
3,, in such scheme, described suspension rod and sun gear coaxially arrange.
4, in such scheme, in the time of assembling, first sun gear is connected with suspension rod, sun gear is located sun gear by suspension rod after engaging with planet wheel; Then, the planet carrier that is engaged with sun gear is fallen into casing, and planet wheel is engaged with ring gear, because ring gear and planet wheel are not blocked, so can rapidly planet wheel be engaged with ring gear; Finally, planet wheel engages with ring gear with sun gear, planet wheel simultaneously, and sun gear falls into internal tooth casing, and suspension rod is taken out from sun gear, has completed the assembling of planetary type gear transmission unit.
The utility model working principle and advantage: the utility model arranges a suspension rod by activity on sun gear, in the time of assembling, be first connected sun gear with suspension rod, sun gear is located sun gear by suspension rod after engaging with planet wheel; Then, the planet carrier that is engaged with sun gear is fallen into casing, and planet wheel is engaged with ring gear, because ring gear and planet wheel are not blocked, so can rapidly planet wheel be engaged with ring gear; Finally, planet wheel engages with ring gear with sun gear, planet wheel simultaneously, and sun gear falls into internal tooth casing, and suspension rod is taken out from sun gear, has completed the assembling of planetary type gear transmission unit.Because the engaging of planet wheel and sun gear, planet wheel can assemble with engaging all of ring gear in the situation that intuitively observing, thereby greatly reduce the assembling difficulty of planetary type gear transmission unit, improved efficiency of assembling.
