Abstract
The utility model discloses a roller chain wheel. The roller chain wheel comprises a body and a matching piece. An annular boss is arranged on the end portion of one side of the body, an annular inscribed groove is arranged on the end portion of the other side of the body, and the internal face of the annular inscribed groove is a threaded face. Threads are arranged on the outer face of the matching piece, and the matching piece is arranged on the annular inscribed groove of the body. In the process of use, firstly the body is arranged on a shaft shoulder of a transmission shaft and limited with the shaft shoulder through the annular boss on one side, then the matching piece is arranged on the other side of the shaft shoulder, the width of the shaft shoulder is slightly larger than that between the annular boss and the matching piece in the process of machining the shaft shoulder, and therefore the matching piece can be guaranteed to be connected with the shaft shoulder closely after being screwed. The roller chain wheel has the advantages that coaxiality of the roller chain wheel and the transmission shaft can be guaranteed, the phenomenon of eccentricity of the roller chain wheel in the process of transmission can not occur, and transmission stability of the roller chain wheel can be guaranteed.
Description
Technical field
The utility model relates to a kind of swing rotational molding machine equipment, specifically the roller chain wheel device on the swinging rotational molding machine.
Background technique
Fixing of the roller chain wheel structure of prior art all is to adopt to install a pin additional in the side of sprocket wheel, by pin roller chain wheel and transmission shaft is fixed.Because pin generally can only one-sidedly arrange, so will inevitably make generation off-centre between roller chain wheel and the transmission shaft after having installed pin additional.Even the circumference at roller chain wheel installs a plurality of pins additional, also be difficult to guarantee the coaxality of roller chain wheel and transmission shaft, so this just makes roller chain wheel cause unsettled problem in the process of transmission.
The model utility content
The purpose of this utility model is a kind of roller chain wheel of design, improves the stability of roller chain wheel in transmission process.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of roller chain wheel, comprise body and counterpart, the end of described body one side is provided with annular boss, the end of described body opposite side is provided with ring-type inscribe groove, inner side surface at ring-type inscribe groove is made as flank of thread, the outer surface of described counterpart is provided with screw thread, and described counterpart is installed on the ring-type inscribe groove of body; The internal diameter of described counterpart is identical with the internal diameter of described annular boss.
The both sides of body have outside extension part.
In the process of using, at first body is installed on the shaft shoulder of transmission shaft, annular boss and the shaft shoulder by a side carry out spacing, and then described counterpart is installed in the opposite side of the shaft shoulder, in the process of the processing shaft shoulder, the width of the requirement shaft shoulder is slightly larger than the width between annular boss and the counterpart, to guarantee that counterpart closely is connected mutually with the shaft shoulder after screwing.
The beneficial effects of the utility model are, can guarantee the coaxality of roller chain wheel and transmission shaft, can not make roller chain wheel produce eccentric phenomenon in the process of transmission, guarantee the stability of roller chain wheel transmission.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the Split type structure figure of the described roller chain wheel of the utility model embodiment.
Fig. 2 is the overall structure figure of the described roller chain wheel of the utility model embodiment.
Embodiment
Shown in Fig. 1-2, the described roller chain wheel of the utility model embodiment, comprise body 1 and counterpart 2, the end of described body 1 one sides is provided with annular boss 3, the end of described body 1 opposite side is provided with ring-type inscribe groove 4, inner side surface at ring-type inscribe groove 4 is made as flank of thread, and the outer surface of described counterpart 2 is provided with screw thread, and described counterpart 2 is installed on the ring-type inscribe groove 4 of body; The internal diameter of described counterpart 2 is identical with the internal diameter of described annular boss 3, and purpose is that the main shaft diameter of the transmission shaft that roller chain wheel installs is only cooperated with counterpart 2 and the annular boss 3 in same aperture.
The both sides of body 1 have outside extension part 5.
In the process of using, at first body is installed on the shaft shoulder of transmission shaft, annular boss and the shaft shoulder by a side carry out spacing, and then described counterpart is installed in the opposite side of the shaft shoulder, in the process of the processing shaft shoulder, the width of the requirement shaft shoulder is slightly larger than the width between annular boss and the counterpart, to guarantee that counterpart closely is connected mutually with the shaft shoulder after screwing.
The beneficial effects of the utility model are, can guarantee the coaxality of roller chain wheel and transmission shaft, can not make roller chain wheel produce eccentric phenomenon in the process of transmission, guarantee the stability of roller chain wheel transmission.
