Abstract
An aim of the utility model is to provide a four-stage transmission structure of a LJJ360 tension leveler speed reducer for satisfying the performance requirements of high strength and large torque, and obtaining compact structure mounting and small occupation space. The four-stage transmission structure of the LJJ360 tension leveler speed reducer comprises the following components: a bevel gear shaft, and a gear which is sleeved on a shaft body of the bevel gear shaft and is provided on a journal of the bevel gear shaft through a key. At two sides of the gear, bearings are respectively sleeved on the bevel gear shaft. Two end faces of an inner ring of the inner ring which is next to a conical part of the bevel gear shaft are respectively positioned through the end faces of the journal and the gear. A through cover is provided at an end face of an outer ring of the other bearing through pressure mounting. A box body is provided outside the through cover. The through cover is sleeved on the bevel gear shaft. The four-stage transmission structure of the LJJ360 tension leveler speed reducer is characterized in that the through cover is hollow and is connected with the box body.
Description
Technical field
The utility model relates to speed reducer component technology field, especially LJJ360 straightening machine speed reducer level Four drive mechanism.
Background technique
It is the end cover formula that existing level Four transmission shaft assembling middle (center) bearing adopts; Though can meet design requirement like this; But because the end cap of sealed type provides the Bearing Installation position can not for the secondary drive shaft parts; Just certainly will remedy, increase cost on the one hand, cause occupation space to strengthen on the other hand with the increase cabinet space.
Summary of the invention
The purpose of the utility model is to provide a kind of LJJ360 straightening machine speed reducer level Four drive mechanism, and when satisfying the performance requirement of high tenacity, big torque, total is installed compact, and it is little to take up room.
The technological scheme of the utility model is:
It comprises bevel gear shaft; Be set in the bevel gear shaft axle body and be arranged on the gear on the bevel gear shaft axle journal through key; Both sides at said gear; Said bevel gear shaft is respectively installed with bearing, and near the said bearing in the tapering of bevel gear shaft, the both ends of the surface of its inner ring are located through the end face of axle journal and gear respectively; Another bearing, the end face of its outer ring is pressed with lid, and its outside is a casing, and said lid is set in said bevel gear shaft, it is characterized in that: said lid is connected for hollow and with said casing.
It is further characterized in that: said bearing is respectively tapered roller bearing, is face-to-face layout; Said lid is connected with bolt with casing through bolt respectively, said bolt and pass through between the lid and be provided with compression spring.
The beneficial effect of the utility model is:
In the said structure of the utility model, the end cap of hollow provides the Bearing Installation position for the secondary transmission part, and it is anchored on casing, has effectively reduced the space of casing, has reduced cost; Rational in infrastructure, processing is easy, the strength of gear teeth is high, bearing adopts tapered roller bearing, guarantees the proper functioning of bevel gear shaft; Impact resistance is big, stable and reliable operation, long service life; Maintenance and Repair are convenient, efficient, further reduced lower cost and less usage space.
Fig. 1 is the overall structure schematic representation of the utility model.
Among the figure: 1 bevel gear shaft, 2 is that bearing, 3 is casing for spring washer, 9 for passing through lid, 7 for hexagon socket head cap screw, 8 for bearing, 6 for gear, 5 for key, 4.
