Abstract
The utility model discloses a dynamic balance combined joint, and belongs to the technical field of dynamic balance. The joint comprises a cover plate and a pipe, wherein the cover plate is fixed at one end of the pipe; and a clamping groove is formed in the pipe. The conventional integrated joint is divided into two parts, and the clamping groove can be easily formed on the inner wall of a pipe fitting through a broaching machine; and compared with the conventional integrated joint, the joint consisting of the two parts has the advantages that the joint is easy to process and convenient to install.
Description
Technical field
The utility model belongs to the dynamic balancing technique field, relates to a kind of dynamic balancing built-up joint that is used to connect universal joint and rotor specifically.
Background technique
Any rotor is around its axis rotation the time, owing to the non-uniform mass with respect to axis produces centrifugal force.This uneven centrifugal action can cause vibration on rotor bearing, produce noise and quicken bearing wear, so that have a strong impact on the performance and the life-span of product.Rotation such as rotor, machine tool chief axis, I. C. engine crankshaft, turbine rotor, gyrorotor and verge ring component are in manufacture process, all need to adjust the mass distribution of rotor along axial direction, make rotor even along the mass distribution of axial direction, could steadily normally turn round so-called dynamic balancing that Here it is.
The machinery that dynamic balancing relies on mainly is exactly dynamic balancing machine, need make rotor high-speed rotation to be measured during dynamic balancing machine work, the vibration of detection rotor.For adapting to various rotor, dynamic balancing machine rotates by the universal joint transmission, and universal joint links to each other with rotor by joint again.
Joint in the past all is the formula of one, and the joint right-hand member is a mounting hole, and the mounting hole inwall is provided with draw-in groove, and the left end of draw-in groove is provided with tool withdrawal groove, and the left side of joint is provided with screw.When joint was installed, bolt passed coupling and is screwed onto in the screw, and coupling and joint are fixed together.One end of rotor is equipped with key, and rotor inserts in the mounting hole, and epitrochanterian key matches with draw-in groove.This joint, maximum problem are exactly the very difficult processing of draw-in groove of rotor inner wall, need with special slot machining, and in order to cooperate the work of slot machine, need be at one section tool withdrawal groove of left end reprocessing of draw-in groove.
Another joint, the joint left end is provided with screw, and the top of joint is provided with two through holes, and the joint right-hand member is a mounting hole.During installation, the installation method of coupling does not change, and when rotor is installed, need process two screws on rotor, and bolt matches with screw after passing through hole.This method, need be on each rotor that need detect processing screw hole, assemble also very inconvenient.
Summary of the invention
The utility model provides a kind of dynamic balancing built-up joint at deficiency of the prior art, greatly reduces processing or assembling difficulty.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of dynamic balancing built-up joint, comprise cover plate and pipe, and described cover plate is fixed on an end of described pipe, and the inside of described pipe is processed with draw-in groove.With the joint separated into two parts of original integral type, and fairly simple at pipe fitting inner wall processing draw-in groove, can operate by broaching machine.
In the technique scheme, described pipe is provided with screw the third, and described screw third communicates with the top of described draw-in groove, and screw third matches with the bolt first.Install after the rotor, utilize the end face of key on the bolt lifting axe, can prevent rotor oscillation.
In the technique scheme, described cover plate is provided with screw first and through hole, and an end end face of pipe is provided with screw second, and bolt second is screwed onto on the screw second after passing through hole.
The beneficial effects of the utility model are: joint is made up of two-part, compares with the joint of integral type in the past, and it is simple to have processing, advantage easy for installation.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, a kind of dynamic balancing built-up joint comprises cover plate 1 and pipe 2, and cover plate 1 is provided with screw first 11 and through hole 12, and cover plate 1 is fixed on an end of described pipe 2, and the inside of pipe 2 is processed with draw-in groove 22.Manage 2 sidewalls and be provided with screw the third 21, screw the third 21 communicates with the top of described draw-in groove 22, and bolt first 24 is screwed onto in the screw the third 21.Be processed with screw second 23 on the one end end face of pipe 2, bolt second 13 is screwed onto on the screw second 23 after passing through hole 12.
Referring to Fig. 3, during assembling, bolt second 31 is passed in the screw first 11 that is screwed onto cover plate 1 on the universal joint 3 behind the through hole.In rotor 4 insertion tubes 2, the key 41 on the rotor 4 matches with draw-in groove 22, and bolt first 24 holds out against the end face of key 41.
