Abstract
The utility model discloses a rotor balance clamp tool, particularly a rotor balance clamp tool used in civil aviation repair. The utility model provides a rotor balance clamp tool used for avoiding impact during the dynamic balance of a fixed disc and a rotor. The clamp tool is arranged on a balance machine. The clamp tool comprises a fan-shaped body, a groove of which the shape fits with that of the fixed disc is arranged on the body, and the rotor balance clamp tool and the fixed disc are fixedly connected. The fixed disc is clamped on the rotor balance clamp tool by the groove on the rotor balance clamp tool, and then, the fixed disc and the rotor balance clamp tool are fixed by screws. The fixed disc moves with the rotor balance clamp tool, so the fixed disc can not be whipped. Operators do not need to disassemble the bearing any longer. Bearing disassembly work hours can be reduced, and damage caused by bearing disassembly can be avoided. The arrangement of the groove on the rotor balance clamp tool can reduce weight.
Description
Technical field
The utility model relates to a kind of rotor balancing frock, especially a kind of rotor balancing frock of using in the civil aviation maintenance.
Background technology
The integrated driving generator of the Boeing B757 of present domestic operation and Air Passenger A320, a fixed disk is arranged below the bearing of its rotor, after rotor decomposes to get off, fixed disk and rotor assembly are mutually independently, rotor rotation can not drive fixed disk, and fixed disk whipping arbitrarily, such situation is unallowable in balance work.So before doing dynamic balancing, need fixed disk is taken off, just can carry out dynamic balancing.Under the present case, decompose bearing to the influence that can not estimate is arranged in useful life of bearing.Bearing in the rotor bearing of some other type or other positions generally all is to decompose the part that the back is just changed, in order that cause damage of bearings when preventing to decompose, collapses at the installation rear bearing and causes the bigger mechanical failure in integrated driving generator inside.
The utility model content
Technical problem to be solved in the utility model provides a kind of fixed disk and rotor of preventing and produce the rotor balancing frock of conflicting when dynamic balancing.
The rotor balancing frock that its technical problem that solves the utility model adopts is installed on the balancing machine, comprises the body that is fan-shaped, and described body is provided with and the suitable groove of fixed disk shape, and this rotor balancing frock is fixedlyed connected with fixed disk.
Further be that this rotor balancing frock is fixedlyed connected with fixed disk by securing member.
Further be that securing member is a screw.
Further be that the excircle end face of body is provided with groove.
The beneficial effects of the utility model are: make fixed disk be stuck on the rotor balancing frock by the groove on the rotor balancing frock, by screw the two is fixed again, fixed disk will move with the rotor balancing frock, thereby can whipping, the operator just needn't decompose bearing this moment again, both can save the man-hour of decomposing bearing, also can prevent to decompose the infringement that bearing causes.On the rotor balancing frock groove weight reduction can also be set.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Parts, position and numbering among the figure: body 1, groove 2, groove 3.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is installed on the balancing machine, comprises the body 1 that is fan-shaped, and described body 1 is provided with the groove 2 suitable with the fixed disk shape, and this rotor balancing frock is fixedlyed connected with fixed disk.In use, the utility model is installed on the balancing machine, this mounting means can connect by modes such as bolt, screw or jigs, and the balance that only need be fixed gets final product.Then rotor is placed on the utility model, epitrochanterian fixed disk is snapped on the groove 2 on the body 1, groove 2 has matching relationship with fixed disk, by modes such as securing member, bonding, clampings fixed disk and the utility model are connected and fixed again, fixed disk is fixed on the balancing machine by the utility model.By the way, when rotor carries out dynamic balancing, when promptly rotating, fixed disk is to be fixed on the balancing machine, therefore can not produce whipping, also can not touch any one position of the rotor of rotation, thereby prevent that whipping is to dynamically balanced influence.Need not to decompose bearing this moment, saved the man-hour of decomposing bearing, also avoided decomposing the infringement that bearing causes.
For the ease of fixedlying connected between dismounting fixed disk and the utility model, the utility model is fixedlyed connected with fixed disk by securing member.For example connect by screw or bolt, also very convenient when dismounting like this.
Because securing member itself occupies certain installing space, in order to reduce this installing space as far as possible, securing member adopts screw.Like this can be directly fixedly connected, help saving installing space by on fixed disk and body 1, screwed hole being set.
For weight reduction, as shown in Figure 2, the excircle end face of body 1 of the present utility model is provided with groove 3.Groove 3 can reduce the weight of body 1 excircle, thereby has effectively reduced the centripetal force that produces when rotating, and helps the balance of whole system.
Claims (4)
