Reliability for guaranteeing to connect when crossbeam adopts the axle shape, described crossbeam is included as the adapter of a shape, the end of taking over is that transition fit is connected with axle bed, and end welding, for further guaranteeing Joint strenght, described crossbeam also comprises being arranged on takes over outside connection hog frame, and the end of described connection hog frame is welded on the axle bed side.
Connect hog frame and damping part for ease of making, described connection hog frame is the square steelframe with two sides that are parallel to each other, described square steelframe can adopt square steel or U-shaped steel, described damping part is the side guard plate of strip, for better cushioning distortion power, be connected by bolt between described side guard plate, axle bed and the adapter, bolt connection itself just can cushion some distortion powers.
The axle bed side is preferably with step surface, and the two ends of square steelframe are provided with the shaft shoulder that cooperates with it.The shaft shoulder abuts against on the side of step surface, in order to the further application of force of axle bed the other side shaped steel frame.
For ease of being connected and fixed, connecting bore is that transition fit is connected on described support shaft and the axle bed, and the end welding, and the end seam, and the face that contacts with the support shaft end face on the axle bed is the plane.
Outside tension force when fully adapting to operation, described crossbeam connecting bore is parallel with the support shaft connecting bore, and the axle bed middle part is ramp structure, and two axle beds are Eight characters shape at the two ends of crossbeam.
Make for convenience, described adapter is that solid axle or the two ends of one are that the solid axle middle part is the unitized construction of hollow tubular, and the end of adapter and axle bed are transition fit, and the end welding.For guaranteeing to connect effectively, if the middle part hollow tubular of taking over, the two ends of hollow tubular are welded on the solid axle, be better power transmission and assembling, by the end at hollow tubular concavo-convex ring is set, the concavo-convex ring that cooperates with it is set in the end of solid axle, and the hole that solid axle is used on the axle bed with two ends cooperates.
Balance shaft of the present utility model is owing to adopt assembled structure, energy buffer portion distortion power, and the outside stressed connection damping part of middle crossbeam, can better alleviate distortion power, and make stressed effect shape preferably, thereby can increase service life.

The specific embodiment
Specific embodiment accompanying drawing is a kind of specific embodiment of the present utility model.It comprises independent and interconnective support shaft 6 separately, axle bed 4 and crossbeam, two support shafts 6 are connected the two ends of crossbeam respectively by axle bed 4, axle bed axially on be respectively equipped with crossbeam connecting bore and support shaft connecting bore, crossbeam and support shaft 6 are the hole axle connection mode that cooperatively interacts with axle bed respectively, the outside stressed side of crossbeam respectively connects a damping part of being made by the damping alloy material, described crossbeam is included as the adapter 1 of a shape, the end of adapter 1 is that transition fit is connected with axle bed, and end welding, described crossbeam also comprises the connection hog frame that is arranged on adapter 1 outside, the end of described connection hog frame is welded on the axle bed side, described connection hog frame is the square steelframe 2 with two sides that are parallel to each other, described square steelframe 2 is square steel or U-shaped steel, described damping part is the side guard plate of strip, described side guard plate 3, axle bed 4 with take over 1 between be connected by bolt 8, described axle bed 4 sides have step surface, the two ends of square steelframe are provided with the shaft shoulder that cooperates with it, connecting bore is that transition fit is connected on described support shaft 6 and the axle bed 4, and end welding, the face that contacts with the support shaft end face on the described axle bed 4 is the plane, described axle bed entablatrance connecting bore is parallel with the support shaft connecting bore, the axle bed middle part is ramp structure, two axle beds 4 are Eight characters shape at the two ends of crossbeam, described adapter 1 is that the solid axle middle part is the unitized construction of hollow tubular for the solid axle of one or two ends, end and the axle bed taken over are transition fit, and the end welding.
