Abstract
The utility model discloses a rotary air intake device used on a frame-type wire strander. The rotary air intake device comprises a hollow shaft and an outer-layer shaft sleeve, wherein the hollow shaft is fixedly sleeved on the tail end of a stranding main shaft, bearings are respectively supported between the hollow shaft and the inner walls at two sides of the outer-layer shaft sleeve, a lug boss is arranged on the inner side wall in the middle of the outer-layer shaft sleeve, a sliding sleeve over against the lug boss is sleeved on the hollow shaft, two seal rings are arranged between the two ends of the sliding sleeve and the lug boss, a press block is arranged outside each seal ring, a gap between the press blocks at two sides and the bearings is a cooling cavity, the cooling cavity is communicated with a cooling air inlet externally, a radial air intake channel is formed on the outer-layer shaft sleeve, an annular concave cavity is formed on the side wall of the sliding sleeve and is communicated with a port of the air intake channel, and an air vent channel is communicated with the lower part of the concave cavity. The rotary air intake device disclosed by the utility model is simple in structure and reliable in use, and the seal rings with special structures have the advantages of thermal resistance, friction resistance, long service life and easiness in replacement.
Description
Technical field
The utility model relates to the electric wire process equipment, specifically belongs to the rotation inlet duct in a kind of strand body that is used for being used for that the compressed air of outside sent into rotary main shaft and is attached thereto on frame type stranding machine.
Background technology
Electric wire industrial expansion along with domestic and international market, to satisfying big specification, the demand of the frame winch of high-speed and high-efficiency strand system conductor is more and more higher, and this frame winch strand body is when rotating twisted wire, need compressed air delivery is entered, this just needs to be equipped with the rotation inlet duct, and existing new-type rotation inlet duct is simple in structure, adopts the sealing ring of special construction, wearing and tearing are few, it is little to generate heat, and long service life is changed easily.Original rotation inlet duct on this equipment, complex structure, rotating speed Gao Shiyi heating, ring wear is fast, and gas leakage easily needs often maintenance.
The utility model content
The purpose of this utility model provides uses the rotation inlet duct on a kind of frame type stranding machine, the rotation inlet duct is simple in structure, uses reliably, and the special construction sealing ring is heat-resisting, rub resistance, long service life, the easy replacing.
The technical solution of the utility model is as follows:
Use the rotation inlet duct on the frame type stranding machine, include the quill shaft that fixed cover is loaded on strand body main shaft tail end, outer axle sleeve, be supported with bearing respectively between quill shaft and the outer axle sleeve both sides inwall, the middle part madial wall of outer axle sleeve has boss, be set with the slip cap that is right against boss on the quill shaft, be provided with two sealing rings between slip cap two ends and the boss, the sealing ring outside is equipped with briquetting, space between both sides briquetting and the bearing is a cooling chamber, the external cold gas air inlet that is connected with of cooling chamber, have inlet channel radially on the outer axle sleeve, have the cavity of annular and the port of inlet channel on the sidewall of slip cap and be connected, the below of cavity is connected outlet passageway.
Described outlet passageway is tilted to, and is connected with outlet pipe.
Constitute the annular seal space of rotation between cavity on described two sealing rings, the slip cap and the boss.
It is sleeved on the utility model on the major diameter quill shaft of afterbody of every section of frame type stranding machine strand body, form by inside and outside two-layer axle sleeve, skin does not change, internal layer rotates with the strand body, support by two bearings between two-layer, middle constitute a rotatable annular seal space by sealing ring and a slip cap, by annular seal space with compressed air from the exterior conductive to a rotating body.Outside closed cavity, have cooling chamber between both sides bearing and the sealing ring briquetting in addition, by being blown into the heat that inner ring friction that another road compressed air cools off slip cap and sealing ring is produced.
The beneficial effects of the utility model are as follows:
The utility model can overcome former rotation inlet duct complex structure, gas leakage easily, the shortcoming of heating, not easy-maintaining, change the shortcoming of sealing ring, this novel rotation inlet duct is simple in structure, uses reliably, and the special construction sealing ring is heat-resisting, rub resistance, long service life is changed easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, use the rotation inlet duct on the frame type stranding machine, include the quill shaft 2 that fixed cover is loaded on strand body main shaft 1 tail end, outer axle sleeve 3, be supported with bearing 4 respectively between quill shaft 2 and the outer axle sleeve 3 both sides inwalls, the middle part madial wall of outer axle sleeve 3 has boss, be set with the slip cap 5 that is right against boss on the quill shaft 2, be provided with two sealing rings 6 between slip cap 5 two ends and the boss, two sealing rings 6, constitute the annular seal space 7 of rotation on the slip cap between 5 cavity and the boss, sealing ring 6 outsides are equipped with briquetting, space between both sides briquetting and the bearing 4 is a cooling chamber 8, the cooling chamber 8 external cold gas air inlets 9 that are connected with, have inlet channel 10 radially on the outer axle sleeve 3, having the cavity of annular and the port of inlet channel 10 on the sidewall of slip cap 5 is connected, the below of cavity is connected outlet passageway 11, and outlet passageway 11 is tilted to, and is connected with outlet pipe 11.
Claims (3)
1. use the rotation inlet duct on the frame type stranding machine, include the quill shaft that fixed cover is loaded on strand body main shaft tail end, outer axle sleeve, it is characterized in that: be supported with bearing respectively between quill shaft and the outer axle sleeve both sides inwall, the middle part madial wall of outer axle sleeve has boss, be set with the slip cap that is right against boss on the quill shaft, be provided with two sealing rings between slip cap two ends and the boss, the sealing ring outside is equipped with briquetting, space between both sides briquetting and the bearing is a cooling chamber, the external cold gas air inlet that is connected with of cooling chamber, have inlet channel radially on the outer axle sleeve, have the cavity of annular and the port of inlet channel on the sidewall of slip cap and be connected, the below of cavity is connected outlet passageway.
