Abstract
The utility model relates to a friction wheel, which comprises a running wheel and a brake wheel, wherein the running wheel is arranged on a working shaft and is made of light rubber, the edge of a running wheel body is depressed from both sides to the middle part, the brake wheel is made of metal and is arranged on a brake shaft, and the edge of a brake wheel body is protruded from both sides to the middle part. The friction wheel can be used for effectively braking various mechanical rotary shafts, and has a low depreciation speed.
Description
Affiliated technical field
The utility model relates to mechanical field, especially, is a kind of friction wheel with braking action.
Background technique
In the mechanical braking field, the general braking plate (friction plate) that adopts is braked the active wheel in the fast rotational, and its action principle is that braking plate is affixed on the active wheel surface, make between the two and rub, under the effect of frictional force, make active wheel stop gradually, yet, in braking process, its friction is sliding friction, and therefore, the wearing and tearing depreciation speed of braking plate is very fast.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of friction wheel, and this friction wheel not only can be braked effectively to all kinds of mechanical rotating shafts, and its depreciation speed is slower.
The technological scheme that its technical problem that solves the utility model adopts is: this friction wheel comprises active wheel and Brake drum, described active wheel is installed on the working shaft, constitute by lightweight rubber, its wheel body edge is from two side direction intermediate recess, described Brake drum is made of metal, be installed on the brake axle, its wheel body edge protrudes in the middle of two side direction.
As preferably, described active wheel both sides clamp two horminess metal plates, are out of shape in extrusion process excessively to prevent described active wheel.
As preferably, the wheel body edge of described active wheel has coarse projection or the lines that is used to increase friction.
As preferably, the density of described Brake drum is at 7.9g/cm
3More than, promptly be not less than the density of iron.
The beneficial effects of the utility model are: this friction wheel in use, only need make the parallel setting of brake axle and working shaft, during braking, make brake axle gradually near working shaft, then Brake drum is close with active wheel gradually, both wheel body edges are meshing with each other, and under the effect of frictional force, Brake drum is accelerated gradually, thereby reduces the kinetic energy of working shaft, and reduces the relative velocity between two-wheeled, because described active wheel and Brake drum are in the engagement separation process, because the features of shape at edge exists sliding friction all the time separately, and owing to described active wheel is made of rubber, in two-wheeled extrusion process, there is bigger elastic strain potential energy, this part potential energy is converted into heat energy the most at last, so kinetic energy is the most depleted, thereby realizes the stop of working shaft, yet, because Brake drum and active wheel remain less relative velocity, so its skimming wear is less, depreciation speed is also less.
Description of drawings
Fig. 1 is the schematic representation of this friction wheel.
Embodiment
In the embodiment shown in fig. 1, this friction wheel comprises active wheel 1 and Brake drum 2, described active wheel 1 is installed on the working shaft, constitute by lightweight rubber, its wheel body edge is from two side direction intermediate recess, described Brake drum 2 is made of metal, is installed on the brake axle, and its wheel body edge protrudes in the middle of two side direction.
Above-mentioned friction wheel, described active wheel 1 both sides clamp two horminess metal plates 3, are out of shape in extrusion process excessively to prevent described active wheel 1.
Above-mentioned friction wheel, the wheel body edge of described active wheel 1 has coarse projection or the lines that is used to increase friction.
Above-mentioned friction wheel, the density of described Brake drum 2 is at 7.9g/cm
3More than, promptly be not less than the density of iron.
Above-mentioned friction wheel in use, only need make the parallel setting of brake axle and working shaft, during braking, make brake axle gradually near working shaft, then Brake drum 2 is close with active wheel 1 gradually, both wheel body edges are meshing with each other, and under the effect of frictional force, Brake drum 2 is accelerated gradually, thereby reduces the kinetic energy of working shaft, and reduces the relative velocity between two-wheeled, because described active wheel 1 and Brake drum 2 are in the engagement separation process, because the features of shape at edge separately exists sliding friction all the time, and since described active wheel 1 constitute by rubber, in two-wheeled extrusion process, there is bigger elastic strain potential energy, this part potential energy is converted into heat energy the most at last, so kinetic energy is the most depleted, thereby realizes the stop of working shaft, yet, because Brake drum 2 remains less relative velocity with active wheel 1, so its skimming wear is less, depreciation speed is also less.
Claims (4)
1. a friction wheel comprises active wheel and Brake drum, it is characterized in that: described active wheel is installed on the working shaft, be made of lightweight rubber, its wheel body edge is from two side direction intermediate recess, and described Brake drum is made of metal, be installed on the brake axle, its wheel body edge protrudes in the middle of two side direction.
