Abstract
The utility model discloses a false shaft member for shafting centering between the active apparatus and the passive apparatus, which is characterized in that the member comprises a main shaft body (1); flange discs are respectively welded to vertical shaft bodies on both ends of the main shaft body (1); 2 to 4 screw bolt pores are provided on the flange disc (2). The utility model is performing shafting centering using a false shaft. The false shaft centering simplifies the workload in the shafting centering, overcomes the shortcoming that articles are large in weight, can not be transported easily, and can be easily broken in the construction field. The false shaft member of the utility model has features of easy manufacturing, low cost, and the centering precision can completely meet the requirement of the design.
Description
Technical field
The present invention relates to be used for the instrument of shafting alignment, more particularly, relate to the shaft-like workpiece of active devices and passive equipment shafting alignment in the shipbuilding process.
Background technology
In the large-scale and complicated device installation process, run into the exigent equipment of shafting alignment problem, particularly setting accuracy through regular meeting, at first be that driven equipment fixedly mount earlier, primary mover (motor, diesel engine etc.) is placed on its pedestal but is fixed then.Equipment can safe and reliable operation and the life-span long, mainly see installation quality, the groundwork in installation process is exactly a shafting alignment.After shafting alignment meets the requirements, fixing primary mover.Intermediate equipments such as plunging joint, tween drive shaft are installed then.Centering work has several different methods, as centering in kind, instrument and meter to medium.Instantiation when full-rotating rudder slurry and drive motor are installed, is a large-scale rigidity plunging joint as in the construction of comprehensive detection ship between active and the passive equipment, if just use plunging joint centering in kind, and very inconvenience.
Summary of the invention
The present invention is intended to make a dummy shaft, and at the two ends of minor axis welded flange, these two flanges match with two plunging joints respectively.Carry out machine up then, the length size is bored 2～4 bolts hole with in kind the same on flange, prepares to match with the half-coupling of master/primary mover.During shafting alignment, dummy shaft is linked to each other with two plunging joints, rotation axis system, with dial gage carry out measurement axis to and radial missing, reach after the accuracy of alignment that equipment producer requires, fixedly primary mover is finished centering and is worked.
In order to achieve the above object, the present invention designs a kind of dummy shaft member that is used for active devices and passive equipment shafting alignment, comprises main shaft.The vertical axis body in the two ends of main shaft is welded with flange respectively; Offer 2-4 bolt hole on the flange, and screw bolt and nut is set by bolt hole.Wherein, described main shaft and true in full accord between active devices and the passive equipment axis system in actual use with axle.
The present invention has designed dummy shaft and has carried out centering, can save time to have avoided unnecessary trouble, has also guaranteed the shafting alignment accuracy requirement simultaneously.Dummy shaft centering of the present invention, convenient and easy, time saving and energy saving, the accuracy of alignment height.This method can be used at plurality of devices shafting alignment manufacture process.
Description of drawings
Fig. 1 is the structural representation that is used for the dummy shaft member of active devices and passive equipment shafting alignment.
The specific embodiment
As shown in Figure 1, the present invention is used for the dummy shaft member of active devices and passive equipment shafting alignment, comprises main shaft 1.The vertical axis body in the two ends of main shaft 1 is welded with flange respectively; Offer 2-4 bolt hole on the flange 2.Wherein, main shaft in the dummy shaft member and true in full accord between active devices and the passive equipment axis system in actual use with shaft size, but in precision and material requirements, can adopt the much lower standard of serious practical axle, thereby reduce the cost that uses actual axial centering greatly.
Utilize the rudder slurry motor propulsion system that adopts on the dummy shaft member comprehensive detection boats and ships of the present invention, between rudder slurry axle drive shaft plunging joint and the motor-driven plunging joint, adopted one the one meter large-scale plunging joint of rigidity how long.If use it to carry out shafting alignment, owing to reasons such as weight, very inconvenience.
That is to say that active devices (being primary mover) realizes with the schemes such as normally adopting plunging joint, tween drive shaft that is connected of passive equipment (promptly being driven machinery).In order to make the equipment reliability service, shafting alignment is the most important thing that equipment is installed.The present invention uses dummy shaft (interim axle) to carry out shafting alignment.The dummy shaft centering method has been simplified the work capacity of shafting alignment, has avoided the shortcoming of (real axis, actual plunging joint) centering in kind, is difficult for carrying greatly as weight in kind, damages easily at the construction field (site) etc.Characteristics such as and dummy shaft member of the present invention has easy making, and cost is low, accuracy of alignment can reach designing requirement fully.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (1)
1. a dummy shaft member that is used for active devices and passive equipment shafting alignment is characterized in that, comprises main shaft (1); The vertical axis body in two ends of described main shaft (1) is welded with flange (2) respectively; Offer 2-4 bolt hole on the described flange (2), and screw bolt and nut is set by described bolt hole.
