Abstract
The invention relates to a milling wheel capable of rapidly changing milling width, belonging to milling wheel structures applied to road milling machines. The milling wheel comprises a drive inner cylinder and a milling outer cylinder, wherein the surface of the milling outer cylinder is provided with a cutting tool, two ends of the drive inner cylinder are supported on a frame through a bearing or the bearing at one end and a speed reducer at the other end; and one end of the milling outer cylinder is connected with the drive inner cylinder through a bolt and the other end is matched and supported on the milling inner cylinder through a small clearance. The milling wheel comprises the drive inner cylinder and the milling outer cylinder, and the drive inner cylinder is sleeved in the milling outer cylinder; and when the milling width is changed, only a connecting bolt between the drive inner cylinder and the milling outer cylinder is dismantled, the milling outer cylinder is drawn out and another milling outer cylinder with required width is replaced, then the connecting bolt is fastened. The milling wheel has simple structure, and realizes convenient and rapid change of the milling width of the milling wheel by the connection structure of the inner cylinder and the outer cylinder.
Description
Technical field
The present invention relates to a kind of milling wheel structure that is applied on the pavement milling machine, especially can change the milling wheel of milling width fast.
Background technology
Pavement milling machine is a kind of road maintenance equipment that is used for the damaged road surface of milling, and its core apparatus is exactly a milling wheel of directly finishing the work of milling road surface.At present, domestic every kind of milling machine all is the milling wheel that is equipped with a fixed width, and these milling wheel two ends are supported on the vehicle frame by a bearing or an end bearing other end reducer.In the milling wheel surface arrangement cutting tool is arranged, the work on cutting road surface is finished in the milling wheel rotation.The milling width of this milling wheel is immutable, and this has just limited the range of application of milling machine, and under some operating mode, the economy of machine is bad.
Summary of the invention
The objective of the invention is to provide a kind of: the milling wheel that can change milling width fast that can change milling width.
The object of the present invention is achieved like this: this milling wheel comprises the driving inner core, and the milling urceolus has cutting tool in milling urceolus surface arrangement; Driving the inner core two ends is supported on the vehicle frame by a bearing or an end bearing other end reducer; Milling urceolus one end is connected with the driving inner core by bolt, and the other end is supported on the milling inner core by little matched in clearance.
Described milling urceolus one end inwall projection has mounting flange, is connected by bolt with the driving inner core; The inwall of the other end has boss, is supported on by little matched in clearance to drive on the inner core.
Described milling urceolus has a plurality of, the width difference of each milling urceolus.
Described driving inner core one end is provided with flange, is connected by bolt with the milling urceolus; The outer wall of the other end has a plurality of steps on different axial locations, each step is by the corresponding milling urceolus that supports different in width of little matched in clearance.
Beneficial effect, owing to adopted such scheme, this milling wheel has the driving inner core, the milling urceolus constitutes, and drives inner core and is socketed in the milling urceolus, when changing milling width, only need the connecting bolt that drives between inner core, the milling urceolus is taken apart, the milling urceolus is extracted out, replaced with another milling urceolus of required width, again that connecting bolt is fastening good.During work, driving torque drives the rotation of milling urceolus by driving inner core, to finish the work on cutting road surface; Like this, milling wheel has just been finished the change of milling width, has reached purpose of the present invention.
Advantage: this milling wheel is simple in structure, and the syndeton by inside and outside tube has realized the change easily and fast of milling wheel milling width.

The specific embodiment
Embodiment 1: a kind of milling wheel that changes milling width, in Fig. 1, Fig. 2, comprise long milling urceolus 1, and short milling urceolus 2 drives inner core 3, rolling bearing 4, vehicle frame 5, reducer 6, belt pulley 7, driven half shaft 8.Drive inner core 3 one ends and be connected with vehicle frame 5 by reducer 6, the other end is supported on the vehicle frame 5 by rolling bearing 8.Belt pulley 7 is connected the input of reducer 6, and the rotary power of whole milling wheel is provided; Long milling urceolus 1 one ends are connected with driving inner core 3 by bolt 9, and the other end is supported on by matched in clearance and drives on the inner core 3.Moment of torsion passes to driving inner core 3 through belt pulley 7 and reducer 6 during work, drives inner core 3 and rotates through the long milling urceolus 1 of bolt 9 drives, finally finishes the work on milling road surface.When changing milling width, pull down bolt 9, extract long milling urceolus 1 out, replace with short milling urceolus 2, connect bolt 9 again, this has just finished milling width change from long to short.
In Fig. 1, Fig. 3, Fig. 5, long milling urceolus adpting flange 1.1 is connected by bolt 9 with driving inner core adpting flange 3.1; The other end has long milling urceolus boss 1.2, is supported on by little matched in clearance to drive on the big boss 3.3 of inner core.
Embodiment 2: in Fig. 2, Fig. 4, Fig. 5, short milling urceolus 2 one ends have short milling urceolus adpting flange 2.1, are connected by bolt 9 with driving inner core adpting flange 3.1; The other end has short milling urceolus boss 2.2, is supported on by little matched in clearance to drive on the inner core small boss 3.2.
Other and embodiment 1 are together.
The above only is embodiments of the invention, according to patent claim of the present invention and description, realizes that by changing or increase different in width milling urceolus more kinds of milling widths changes scope, all should still belong to the scope that patent of the present invention contains.
