Abstract
The utility model discloses a modular eccentric shaft, it includes a main shaft, a disc and a cam pin, the disc one be provided with a centre bore on the surface, the centre bore is square blind hole, the square connecting portion of one end for matching with the centre bore of main shaft, square connecting portion close -fitting is pegged graft in the centre bore, another of disc is provided with an eccentric orfice on the surface, and the eccentric orfice is the blind hole and for the screw hole, the threaded connection portion of one end for matching with the eccentric orfice of cam pin, and the threaded connection of threaded connection portion is in the eccentric orfice. The utility model discloses make main shaft, disc and eccentric shaft to change alone.
Description
Technical field
The utility model relates to a kind of combined bias shaft.
Background technique
The eccentric shaft of prior art generally comprises main shaft, disk and cam pin, main shaft is connected to one of disk on the surface, cam pin be connected to disk another on the surface, the axis of main shaft and the axis of disk are on the same line, not on the same line, main shaft, disk and cam pin are integral type structure for the axis of cam pin and the axis of disk.Above-mentioned eccentric shaft, because main shaft, disk and cam pin are integral type structure, like this, when main shaft, disk or cam pin damage, just need to change whole eccentric shaft, replacement cost is higher.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of combined bias shaft, and it makes main shaft, disk and eccentric shaft to change separately.
For solving the problems of the technologies described above, the combined bias shaft that the utility model provides, it comprises a main shaft, a disk and a cam pin, one of described disk is provided with a center hole on the surface, center hole is square blind hole, one end of main shaft is the square joint matched with center hole, and square joint close-fitting is plugged in center hole;
Another of disk is provided with an eccentric opening on the surface, and eccentric opening is blind hole and is tapped hole, and one end of cam pin is the threaded joints matched with eccentric opening, and threaded joints is threaded in eccentric opening.
As preferably, another of described disk is provided with a supporting sleeve on the surface, and supporting sleeve is nested with on cam pin.
As preferably, described cam pin is provided with axially through through hole.
As preferably, one of described disk is provided with a balancing weight on the surface, and balancing weight and cam pin lay respectively at the both sides of main shaft.
As preferably, described main shaft, disk and cam pin are made by No. 45 steel.
After adopting above structure, the utility model compared with prior art, has following advantage:
In the utility model, because main shaft is plugged in center hole by square joint, the cam pin portion of being threaded connection screws in eccentric opening, like this, main shaft, disk and cam pin can split mutually, when main shaft damages, main shaft can be pulled down and change separately, when disk damages, disk can be pulled down and change separately, when cam pin damages, cam pin can be pulled down and change separately, so just without the need to changing whole eccentric shaft, replacement cost is reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model combined bias shaft comprises main shaft 1, disk 2 and a cam pin 3, one of described disk 2 is provided with a center hole 201 on the surface, center hole 201 is square blind hole, one end of main shaft 1 is the square joint 101 matched with center hole 201, and square joint 101 close-fitting is plugged in center hole 201.
Another of disk 2 is provided with an eccentric opening 202 on the surface, and eccentric opening 202 is blind hole and is tapped hole, and one end of cam pin 3 is the threaded joints 301 matched with eccentric opening 202, and threaded joints 301 is threaded in eccentric opening 202.
Another of described disk 2 is provided with a supporting sleeve 4 on the surface, supporting sleeve 4 is nested with on cam pin 3, like this, supporting sleeve 4 can play supporting and location effect to cam pin 3, the stressed generation of cam pin 3 can be avoided to rock and threaded joints 301 is got loose in eccentric opening 202, make cam pin 3 fixing more firm.
Described cam pin 3 is provided with axially through through hole 302, makes the weight of cam pin 3 lower, and the material of processing needed for cam pin 3 reduces, and saves manufacture cost.
One of described disk 2 is provided with a balancing weight 5 on the surface, balancing weight 5 and cam pin 3 lay respectively at the both sides of main shaft 1, like this, owing to being provided with balancing weight 5, disk 2 can be made when rotating, weight distribution on disk 2 balances more, can avoid the vibrations that disk 2 produces by a relatively large margin due to weight distribution inequality.
Described main shaft 1, disk 2 and cam pin 3 are made by No. 45 steel, like this, when machining spindle 1, disk 2 and cam pin 3, are easier to carry out cutting.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
