Abstract
The utility model discloses a nested type roll ball joint device which comprises an inner gear sleeve component 1 and an outer gear ring component 2. The inner gear sleeve component comprises an inner gear sleeve and a flange plate. Grooves and a key groove are also formed in the inner gear sleeve. Outer connection location holes are also formed in the flange plate. The outer gear ring component comprises an outer gear ring, an outer gear shaft and a flange plate, wherein grooves, roll balls and springs are arranged on the outer gear ring, outer connection location holes are formed in the flange, the outer gear ring component 2 is embedded into the inner gear sleeve component 1, and an integral whole is formed by the outer gear ring component 2 and the inner gear sleeve component 1. When the nested type roll ball joint device works, a big cross angle between shafts can be allowed, changes of contact relative position of two half-cylinder longitudinal grooves and the roll balls are not big and are elastic. The nested type roll ball joint device has the advantages of being big in bearing capacity, stable in operation, long in service life, high in transmission efficiency and the like.
Description
Technical field
The utility model relates to a kind of coupling, especially a kind of nesting type ball docking adapter.
Background technique
Nowadays, known coupling is widely used in the working online of motor, turbo machine, Reciprocating engine, it is of a great variety, according to the relative position of coupled diaxon and the change conditions of position, can be divided into permanent coupling and movable coupling, existing shaft coupling transmission efficient is low, and the separating vibration noise is large, fragile, be not suitable for the connection of high-speed drive shaft.In addition, can not eliminate impact, can not eliminate the adverse consequences that causes owing to diaxon inclination or decentraction, these all are that we are badly in need of improved.
Summary of the invention
The purpose of this utility model just is to overcome the deficiency of prior art, and a kind of nesting type ball docking adapter simple in structure, reasonable in design is provided.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of nesting type ball docking adapter includes internal tooth casing parts 1 and external toothing parts 2, and external toothing parts 2 embed 1 li of internal tooth casing parts, consists of an integral body.Wherein:
Described internal tooth casing parts 1 include again internal tooth casing 1.1 and flange plate 1.2, and the inner side surface of the outer side surface of internal tooth casing 1.1 and flange plate 1.2 closely is connected mutually.
Described external toothing parts 2 include again external toothing 2.1, external tooth axle 2.2 and flange plate 2.3, and external toothing 2.1 closely is connected with the front end of external tooth axle 2.2, and the inner side surface of flange plate 2.3 closely is connected with the middle part of external tooth axle 2.2.
The utility model makes it consist of a workable integral body 1.1 li of the internal tooth casings in the external toothing 2.1 embedding internal tooth casing parts 1 in the external toothing parts 2.
Remarkable advantage of the present utility model is as follows:
1. bearing capacity is large, smooth running;
2. the separating vibration noise is little, and temperature is low, and is energy-conservation;
3. long service life, transmission efficiency is high;
