Abstract
The utility model provides a friction wheel structure. The friction wheel structure comprises a rotating shaft and a friction wheel, wherein a lug boss is arranged at the outer surface of the rotating shaft; a lug boss is arranged at the inner surface of the friction wheel; and the lug boss on the rotating shaft is connected with the lug boss on the friction wheel through a bolt. The friction wheel structure has the beneficial effects of: reducing processing cost and being mounted conveniently as the technical scheme is adopted, and the friction wheel is connected with the rotating shaft through a bolt in a structure of screwing the friction wheel rapidly; generating no sliding motion to have friction with a bearing cover, rotating flexibly and freely and being more convenient to operate due to the positioning of the bearings at two sides; and achieving the advantages of a simple structure, convenience in maintenance, high production efficiency and the like.
Description
Technical field
The invention belongs to mechanical equipment technical field, especially relates to a kind of structure of friction wheel.
Background technique
In existing technology, adopt gear to connect in the structure of revolving soon friction wheel in fast spigot, be provided with tooth outside rotating shaft, be provided with tooth outside friction wheel, friction wheel is enclosed within rotating shaft and by gear and connects.Exist processing cost large, gear shaft has offset phenomena in rotary course, with the bearing cap friction, produces resistance, moves the technical problems such as constant.
Summary of the invention
The problem that the invention will solve is to provide a kind of structure of friction wheel, especially is fit to the use of revolving soon structure of friction wheel in fast spigot.
For solving the problems of the technologies described above, the technological scheme that the invention is adopted is: a kind of structure of friction wheel, comprise rotating shaft and friction wheel, it is characterized in that: be provided with boss outside described rotating shaft, described friction wheel inner face is provided with boss, and the boss on the boss in described rotating shaft and described friction wheel is bolted.
Advantage and good effect that the invention has are: owing to adopting technique scheme, the structure of revolving soon friction wheel adopts friction wheel and rotating shaft to be bolted, processing cost reduces, easy for installation, because two side bearings are located, can not produce and slide and the bearing cap friction, rotate nimbly and freely, more convenient to operate; Have simple in structure, easy to maintenance, the manufacturing efficiency advantages of higher.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is the structural representation of the invention.
In figure:
1, rotating shaft 2, friction wheel 3, bearing cap 4, bolt
Embodiment
As shown in Figure 2, a kind of structure of friction wheel of the invention comprises rotating shaft 1 and friction wheel 2, and described rotating shaft 1 outside is provided with boss, and described friction wheel 2 inner faces are provided with boss, and the boss in described rotating shaft 1 is connected by bolt 4 with boss on described friction wheel 2.
The working procedure of this example: the structure of revolving soon friction wheel 2 adopts friction wheel 2 to be connected by bolt 4 with rotating shaft 1, and processing cost reduces, and is easy for installation, because two side bearings are located, can not produce to slide and the bearing cap friction, rotates nimbly and freely, and is more convenient to operate.
An above embodiment to the invention has been described in detail, but described content only is the preferred embodiment of the invention, can not be considered to for the practical range that limits the invention.All equalizations of doing according to the invention application range change and improve etc., within all should still belonging to the patent covering scope of the invention.
