Abstract
The utility model discloses a roller main shaft of a twisting machine. The roller main shaft comprises a main shaft body (1), wherein a key groove hole (2) is formed in the outer surface of the main shaft body (1) along the axis; an annular boss (3) is arranged on one side, close to the key groove hole (2), of the outer surface of the main shaft body (1); a thread hole (5) is formed in the other side, close to the key groove hole (2), of the outer surface of the main shaft body (1). According to the roller main shaft of the twisting machine, the key groove hole is formed in the outer surface of the main shaft body along the axis, a key is placed in the key groove hole to prevent a transmission gear from idling on the main shaft body, and the annular boss and the thread hole are formed in the main shaft body to prevent the transmission gear from sliding along the axial direction. The roller main shaft of the twisting machine is simple in structure and quite convenient to use; the transmission gear is effectively prevented from being loosened; better limiting and fastening effects are achieved in the axial direction and the radial direction; the failure rate of equipment is reduced; a production line of the twisting machine can run efficiently.
Description
Technical field
The utility model relates to a kind of drum spindle, relates in particular to a kind of twisting machine drum spindle, belongs to textile processing equipment field.
Background technology
Twisting machine drum spindle needs different rotations at present, on existing twisting machine drum spindle, cover has travelling gear, the general direct employing interference fits of travelling gear and twisting machine drum spindle, after time is long the situation lower transmissioning gear of load hold produce very much loosening, even cause the situation of travelling gear idle running, directly cause twisting machine cylinder to stop operating, very unfavorable to the efficient uninterrupted running of production line.
As Chinese patent notification number is: CN203114869U, the day for announcing is: the utility model patent on August 7th, 2013 discloses a kind of power transmission shaft, comprises axis body, and axis body top and bottom are equipped with spline, in the middle of axis body, be provided with four equidistant reinforcements, reinforcement below is provided with annular knurl.But the defect of this structure is: complex structure, and after being installed, travelling gear easily throws off and idle running, and travelling gear is not easy to spacing and fastening, uses inconvenient.
Summary of the invention
The purpose of this utility model is easily to throw off and idle running for the travelling gear of installing on existing twisting machine drum spindle, travelling gear is not easy to fastening defect and deficiency, provide a kind of simple in structure, travelling gear is installed on twisting machine drum spindle and can not be thrown off and dally, be convenient to spacing and fastening a kind of twisting machine drum spindle.
For achieving the above object, technical solution of the present utility model is: a kind of twisting machine drum spindle, comprise main shaft body, on the outer surface of described main shaft body, along axis, offer dowel hole, a side near dowel hole on the outer surface of main shaft body is provided with annular boss, and the opposite side near dowel hole on the outer surface of main shaft body offers screwed hole.
One end of described main shaft body is provided with end step surface.
The length of described dowel hole is 52 millimeters, and wide is 12 millimeters, is 4 millimeters deeply.
The diameter of described annular boss is greater than 10 millimeters-30 millimeters of main shaft body maximum gauges, and the thickness of annular boss is 6 millimeters-12 millimeters.
The beneficial effects of the utility model are:
1, the utility model offers dowel hole along axis on the outer surface of main shaft body, by placing and be good for to prevent that travelling gear from dallying on main shaft body in dowel hole, for preventing that travelling gear from sliding vertically, on main shaft body, be provided with annular boss and screwed hole.
2, of the present utility model simple in structure, use easily, effectively prevented the loosening of travelling gear, in axial and footpath, upwards all play spacing and fastening effect preferably, reduced the fault rate of equipment, be conducive to the high-efficiency operation of twisting machine production line.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of Fig. 1.
In figure: main shaft body 1, dowel hole 2, annular boss 3, end step surface 4, screwed hole 5.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is described in further detail:
Referring to Fig. 1, Fig. 2, a kind of twisting machine drum spindle of the present utility model, comprise main shaft body 1, on the outer surface of described main shaft body 1, along axis, offer dowel hole 2, a side near dowel hole 2 on the outer surface of main shaft body 1 is provided with annular boss 3, and the opposite side near dowel hole 2 on the outer surface of main shaft body 1 offers screwed hole 5.
One end of described main shaft body 1 is provided with end step surface 4.
The length of described dowel hole 2 is 52 millimeters, and wide is 12 millimeters, is 4 millimeters deeply.
The diameter of described annular boss 3 is greater than 10 millimeters-30 millimeters of main shaft body 1 maximum gauges, and the thickness of annular boss 3 is 6 millimeters-12 millimeters.
One end of main shaft body 1 is provided with end step surface 4, on the outer surface of main shaft body 1, along axis, offers dowel hole 2, and the length of dowel hole 2 is 52 millimeters, and wide is 12 millimeters, is 4 millimeters deeply.A side near dowel hole 2 on the outer surface of main shaft body 1 is provided with annular boss 3, and main shaft body 1 is after installing gear like this, and the end face of gear can withstand on the side of annular boss 3, plays certain position-limiting action.The diameter of annular boss 3 is greater than 10 millimeters-30 millimeters of main shaft body 1 maximum gauges, and the thickness of annular boss 3 is 6 millimeters-12 millimeters.
Opposite side near dowel hole 2 on the outer surface of main shaft body 1 offers screwed hole 5, after travelling gear is installed, by the bolt of screwing on, plays the effect that prevents that travelling gear from exiting in screwed hole 5.The utility model is by arranging dowel hole 2, in the interior placement of dowel hole 2, be good for to prevent that travelling gear from dallying on main shaft body 1, for preventing that travelling gear from sliding vertically, on main shaft body 1, be provided with annular boss 3 and screwed hole 5, good anti-drop effect, is used easily.
