The effect of adjusting.Its principle is that the lesser one end of gravity is adjusted and changed using counterweight ring.On the other hand, it is adjusted in gravity
On, the installation of counterweight ring is more convenient, combined by upper half ring and lower semi-ring, by two nuts, can and mandrel on
Nut, so as to adjust any position that counterweight ring is on mandrel.Two nuts will match to the left and right sides of counterweight ring
Weight ring, which clamps, realizes fixation.
Concrete scheme as the utility model can be preferred are as follows: and one end of the upper half ring and lower semi-ring is hinged,
The hole of upper half ring and lower semi-ring is opposite.
By above-mentioned setting, upper half ring and lower semi-ring are connected with each other, can not it is easier that upper half ring and lower semi-ring are respectively lost
Together with opposite holding, it and does not influence to install, it is convenient to operate.
Concrete scheme as the utility model can be preferred are as follows: a circle groove is provided on the side wall of the counterweight ring,
Rubber ring is installed, the rubber ring is located at upper half ring or the groove location of lower semi-ring is fixed by glue in the groove.
By above-mentioned setting, in order to which rubber ring can mutually be contradicted with nut so that nut and counterweight ring it
Between due to rubber ring presence and further enhance frictional force so that nut is not easy to loosen, connect stronger.
Concrete scheme as the utility model can be preferred are as follows: is additionally provided on the counterweight ring several equally distributed
Holding tank, the holding tank is for accommodating balance mud, the end face seal of the opening of holding tank by nut.
By above-mentioned setting, in order to improve the precision of adjusting, to be further improved on holding tank, mud is balanced using filling
Amount number, further to adjust and change counterweight, to realize the adjustment of weight of counterweight ring.
The utility model has the technical effect that following aspect: preliminary adjusting can be played to mandrel or so gravity
Effect changes the matching degree of mandrel or so gravity.The position of centre of gravity for adjusting mandrel is easier, convenient.

Specific embodiment
Below in conjunction with attached drawing, specific embodiment of the present utility model is described in further detail, so that the utility model skill
Art scheme is more readily understood and grasps.
Embodiment 1:
A kind of constant velocity cardan joint drive assembly, refering to what is shown in Fig. 1, including ball in internal spherical cage structure, ectosphere basket structure, connection
The mandrel of basket structure and ectosphere basket structure.It is existing structure for internal spherical cage structure and ectosphere basket structure, does not make improvements,
But for there is internal spherical cage structure and ectosphere basket structure, there is weight differences in existing structure.Therefore, refering to what is shown in Fig. 2,
There is screw thread on the outer wall of mandrel, at least two nut is socketed on mandrel, nut is usually arranged to even numbers.Nut
Weight it is relatively uniform.This programme can mainly reduce weight difference.A counterweight ring, counterweight ring packet are fastenedly connected between two nuts
Upper half ring and lower semi-ring are included, upper half ring and lower semi-ring are connected together.
Internal spherical cage structure and ectosphere basket structure occupy different weight respectively, and this programme may be implemented to adjust, and can play
The effect of balance mandrel or so gravity.So that the gravity of mandrel is in the midpoint of mandrel, play the role of tentatively adjusting.Its
Principle is that the lesser one end of gravity is adjusted and changed using counterweight ring.On the other hand, in gravity adjusting, the peace of counterweight ring
Fill more convenient, combined by upper half ring and lower semi-ring, by two nuts, can and mandrel on nut, so as to
It adjusts counterweight ring and is in any position on mandrel.Two nuts are realized admittedly to which the left and right sides of counterweight ring clamps counterweight ring
It is fixed.
Further design, refering to what is shown in Fig. 3, one end of upper half ring and lower semi-ring is hinged, upper half ring and lower semi-ring
Hole is opposite.Upper half ring and lower semi-ring are connected with each other, and not it is easier that upper half ring and lower semi-ring are respectively lost, opposite can be kept
Together, it and does not influence to install, it is convenient to operate.
Be provided with a circle groove on the side wall of counterweight ring, rubber ring be installed in groove, rubber ring be located at upper half ring or under
The groove location of semi-ring is fixed by glue.In order to which rubber ring can mutually be contradicted with nut, so that nut and matching
Frictional force is further enhanced due to the presence of rubber ring between weight ring, so that nut is not easy to loosen, is connected stronger.
Several equally distributed holding tanks are additionally provided on counterweight ring, holding tank is opened for accommodating balance mud, holding tank
End face seal of the mouth by nut.In order to improve the precision of adjusting, to be further improved on holding tank, filling balance mud is utilized
Amount number, further to adjust and change counterweight, to realize the adjustment of weight of counterweight ring.
Use operating process: two nuts have been on mandrel, and counterweight ring is opened, and snap onto two nuts of mandrel
Between, then rubber ring is fastened in groove, and then that two nuts are close to counterweight ring and fixed, nut end face contradicts at this time
To rubber ring.Before this, it is finely adjusted if necessary, balance mud can be added in holding tank, then tightens nut again.
Certainly, the representative instance of above only the utility model, in addition to this, the utility model can also have other a variety of
Specific embodiment, all technical solutions formed using equivalent substitution or equivalent transformation all fall within the requires of the utility model protection
Within the scope of.
