Abstract
The invention provides a balance shaft, which is mainly used for buffering twisting power caused by uneven force on both ends of the balance shaft due to overloading turbulence of an automobile. The balance shaft comprises threaded shafts, shaft seats and a beam which are designed in a split manner; the two threaded shafts are connected to the two ends of the beam through the shaft seats; the beam is composed of combined pipe shaft round steel and a fastening side guard plate on the outer side; and the two threaded shafts are fixed onto a holder. The balance shaft is characterized in that the lower parts of the shaft seats are also provided with lower supporting bodies parallel to the inner side of the holder, and the lower supporting bodies of the two threaded shafts are fixedly connected by a connection shaft. The balance shaft has the beneficial effects that the shaft seats adopt lengthened structures, the lower parts of the shaft seats are fixedly connected, the strength of the shaft seats is improved, bearing of a square steel frame and the side guard plate is effectively shared, the inside stress of the holder is also shared, and therefore the service life can be prolonged.
Description
Technical field
The present invention is a kind of balance shaft, is mainly used in the heavily loaded distortion power caused balance shaft two ends unbalance stress that jolts of buffering automobile.
Background technology
Existing balance shaft, performance can be better the balance shaft of patent No. ZL201320057915.7, but the axle bed of this balance shaft is shorter, only there are top and two, middle part axis hole, lower end does not connect mutually, inside the stressed support all transferring to both sides of lower end, support lower inside is caused easily to rupture, affect service life, simultaneously due to axle bed shorter stressed time to share the area of carrying less, cause the square steelframe that is connected with axle bed top and side guard plate to be shared stressed comparatively large, thus easily cause square steelframe and side guard plate easily to rupture, affect service life.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides the higher and balance shaft of long service life of a kind of intensity.
A kind of balance shaft, comprise the threaded shaft of split design, axle bed and crossbeam, two threaded shafts are connected to the two ends of crossbeam respectively by axle bed, crossbeam is made up of the fastening side guard plate combining tubular axis round steel and outside, two threaded shafts are separately fixed on support, it is characterized in that: the bottom of described axle bed is also provided with the lower support body with support inside parallel, is fixedly connected with between the lower support body of two axle beds by spindle.
The present invention has processed lower support body in the lower end of axle bed, and the lower support body of both sides axle bed is fixedly connected with by spindle, strengthening the structure of axle bed with this, making axle bed be unlikely to when bearing larger power to damage, extend life-span of axle bed, what alleviate inside two side stands is stressed simultaneously.
For ease of realizing being fixedly connected with of two axle beds, following structure can be adopted to fix, and the lower end of described lower support body is also provided with axis hole, is transition fit between spindle and axis hole, and welding edges; Or adopt other to be fixedly connected with mode, as described in the lower end of lower support body be also provided with axis hole, be free-running fit between spindle and axis hole, and be respectively equipped with knock hole in the radial direction of spindle and axis hole, and be provided with straight pin in knock hole; For ensureing the contact of axle bed and support, prevent local pressure excessive, inside described support, the plane of middle side part outer with axle bed coordinates.
When using balance shaft of the present invention, because axle bed adopts elongate structure, add axle bed area, effectively share the carrying of square steelframe and side guard plate, because axle bed lower end, both sides is fixedly connected with, make originally to need the side force born of carrying on a shoulder pole inside side stand to have axle bed to bear, because axle bed is elongate structure, its load-carrying capacity is very strong, thus can increase service life.

In figure, 1, combination tubular axis round steel, 2, side guard plate, 3, axle bed support, 4, axle bed, 5, threaded shaft, 6, spindle, 7, straight pin.
detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.It comprises threaded shaft 5, axle bed 4 and the crossbeam that split designs, two threaded shafts 5 are connected to the two ends of crossbeam respectively by axle bed 4, crossbeam is made up of the fastening side guard plate 2 combining tubular axis round steel 1 and outside, two threaded shafts 5 are separately fixed on support 3, it is characterized in that: the bottom of described axle bed 4 is also provided with the lower support body with support inside parallel, is fixedly connected with between the lower support body of two axle beds 4 by spindle 6.
Balance shaft of the present invention is when making, the fixed form of spindle 6 and the lower support body on the axle bed of both sides, can adopt following two kinds of modes, the first is provided with axis hole in the lower end of lower support body, is transition fit between spindle 6 and axis hole, and welding edges, it two is that the lower end of lower support body is provided with axis hole, is free-running fit, and is respectively equipped with knock hole in spindle 6 and the radial direction of axis hole between spindle 6 and axis hole, and in knock hole, be provided with straight pin 7
For ensureing the contact of axle bed and support, prevent local pressure excessive, inside described support 3, the plane of middle side part outer with axle bed coordinates.
Balance shaft of the present invention adopts elongate structure due to axle bed, and lower end is fixedly connected with, and adds the intensity of axle bed, effectively reduces the carrying of square steelframe and side guard plate, also reduces the support inside to two side stands simultaneously, thus can increase service life.
