Abstract
The utility model discloses a friction device, which mainly consists of an outer shell, a friction piece, a friction cone, a pin, a rotating axis, a dish-shaped spring, a pulling bearing and a screw cover. The outer shell is a cone, whose outer wall can be fixed and connected on the machine support; the rotating axis with the friction cone taken as an integrative component is covered and arranged inside of the outer shell; the friction piece is arranged between the outer wall of the friction cone and the inner wall of the outer shell; the dish-shaped spring, the pulling bearing and the screw cover are covered on the rotating axis. Because the friction force comes from the friction piece arranged between the outer wall of the friction cone and the inner wall of the outer shell contained with the friction cone, in the operation process, the friction rotation is formed between the friction piece felt on the friction piece of the inner wall of the outer shell and the outer wall of the friction cone; the friction resistance force can change the axis-directional pressure forced on the friction cone by rotating the screw cover so as to reach the purpose for adjusting the friction resistance force. The adjustment for the friction resistance force is easy to be realized.
Description
Technical field
The utility model relates to a kind of body-building apparatus, particularly relates to a kind of strigil.
Background technology
At present, there is exercise and fitness equipment miscellaneous the market, as various treadmills, bicycle etc.In order to reach the body-building purpose, usually these sports equipments all need the resistance of motion, and traditional mechanism mostly adopts is traditional mechanical friction type mechanism, and mostly there be the big or small wayward of frictional resistance in the mechanical friction type mechanism of commonly using, shortcomings such as difficult the realization finely tuned, and security performance is not good.
The utility model content
The purpose of this utility model is to provide a kind of size control easily of frictional resistance, easily realizes the strigil of fine setting.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of strigil, and it mainly is made up of shell, friction plate, friction cone, rotating shaft, disk spring, thrust bearing, thread bush; Described shell is a bullet, and its outer wall can be fixed on the outside frame; Described friction cone is connected in the rotating shaft by pin key, and the rotating shaft that is socketed with friction cone is nested with in the enclosure as a global facility, and the outer wall of friction cone forms cone match with the outer casing inner wall that holds friction cone; Between friction cone outer wall and outer casing inner wall, friction plate is set; Described disk spring, thrust bearing, thread bush are socketed in the rotating shaft in regular turn, form the relation that leans between boss, disk spring, thrust bearing, the thread bush; Described thread bush by the external thread bolt connection on it on the base plate of shell.
Described friction cone outside is taper, and a boss is established to the upper edge in self-friction cone inner bottom surface middle part, and these boss central authorities offer a through hole; Described rotating shaft is connected in the logical second of boss central authorities by pin key.
It is that the two ends of disk spring lean respectively on the inner face of the boss of friction cone and thrust bearing that leaning between described bearing block, disk spring, thrust bearing, the thread bush closed, and the outer face of thrust bearing leans on thread bush.
The utility model also comprises a unilateral bearing, and friction cone is socketed in the rotating shaft by unilateral bearing.
The affixed regulating handle in described thread bush outer end.
Described friction plate is bonded on the outer casing inner wall.
After adopting such scheme, the utlity model has following advantage:
(1) outer wall of the utility model friction cone and hold and be cone match between the outer casing inner wall of friction cone, friction cone operate steadily in rotary course, evenly.
(1) since frictional resistance just derive from the outer wall that is arranged on friction cone and hold friction plate between the outer casing inner wall of friction cone, in motion process, be bonded between the outer wall of the friction plate of outer casing inner wall and friction cone and form frictional rotation, the big I of its frictional resistance changes the axial compressive force that is applied on the friction cone by the rotation thread bush, be the frictional force between the outer wall of friction cone and the outer casing inner wall that holds friction cone, thereby reach the purpose of adjusting the frictional resistance size, the size adjustment of frictional resistance realizes easily.
(2) owing to be that to change the axial compressive force that is applied on the friction cone by thread bush be by threaded adjusting, can realize fine setting easily.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is a side view of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of strigil, and it mainly is made up of shell 1, friction plate 2, friction cone 3, pin key 4, rotating shaft 5, disk spring 6, thrust bearing 7, thread bush 8, regulating handle 9, unilateral bearing 10.
Described shell 1 is a bullet, and its outer wall can be fixed on the outside frame 20; Described friction cone 3 outsides are taper, and a boss 31 is established to the upper edge in self-friction cone 3 inner bottom surfaces middle part, the through hole 32 that these boss 31 central authorities offer, and described rotating shaft 5 is connected in the through hole 32 of boss 31 central authorities by pin key 4.Friction cone 3 is socketed in the rotating shaft 5 by unilateral bearing 10, and the rotating shaft 5 that is socketed with friction cone 3 is nested with in shell 1 together as a global facility, and the outer wall of friction cone 3 forms cone match with shell 1 inwall that holds friction cone 3; At friction cone 3 outer walls the friction plate 2 of damping action is set between shell 1 inwall, friction plate 2 is bonded on shell 1 inwall, when rotating shaft 5 drives friction cones 3 rotations, friction cone 3 be bonded in shell 1 inwall friction plate 2 and form the friction rotation.
Described disk spring 6, thrust bearing 7, thread bush 8 are socketed in the rotating shaft 5 in regular turn, the two ends of disk spring 6 lean respectively on the inner face of the boss 31 of friction cone 3 and thrust bearing 7, the outer face of thrust bearing 7 leans on thread bush 8, forms the relation that leans between boss 31, disk spring 6, thrust bearing 7, the thread bush 8; Described thread bush 8 by the external thread bolt connection on it on the base plate 11 of shell 1, the affixed regulating handle 9 in thread bush 8 outer ends.
Operation principle of the present utility model:
External force drives rotating shaft 5 rotations, and rotating shaft 5 drives friction cones 3 rotations, the rotation of friction cone 3 opposite shell 1 inwall, and the outer wall of friction cone 3 leans mutually and contacts with being bonded in shell 1 inwall friction plate 2, forms friction and rotates.People can be by being rotatably connected on the regulating handle 9 of thread bush 8 outer ends, make thread bush 8 forward or reverse, make thread bush 8 move in or out vertically, apply an axial compressive force by the boss 31 that leans on thread bush 8, thrust bearing 7, disk spring 6 and the friction cone 3 together to friction cone 3, be the frictional force between the outer wall of friction cone 3 and shell 1 inwall that holds friction cone 3, thereby reach the purpose of adjusting the frictional resistance size.When thread bush 8 moves inward, frictional resistance increases, and outwards moves, and frictional resistance reduces.
