Abstract
The utility model provides an improve fan abrasion strength's bush device. The bushing device is circular in shape, a through hole is formed in the middle of the bushing device, and a notch is formed in one side of the through hole; 4 semicircular flanges are arranged on the periphery of the groove, a circle of circular flange is arranged on the periphery of the groove, and a threaded through hole is drilled in the side surface of each semicircular flange and passes through the notch; the end face is provided with a dismounting hole which is a threaded hole. The outline of the 4 semicircular flanges and the outline of the circular flanges are matched with the internal structure of the fan bracket, so that the lining device is effectively prevented from moving under the action of external force and falling off. The semicircular flanges are clamped in the fan bracket to prevent rotation; the circular flange prevents play of the bushing arrangement inside the fan bracket. The material of bushing device is cast iron 200, and the fan support is the aluminium material, and the wearability of cast iron is stronger than the aluminium material far away, increases the wearability that the cast iron bush can effectively promote fan assembly position in the fan.
Description
Technical field
The utility model is related to the fans on engine, and in particular to the bushing device on a kind of fan, for promoting wind
Fan the wearability and intensity of rigging position.
Background technology
The generator of my company production is mainly supplied to army, and military generator to weight and volume requirement increasingly
Sternly.In order to effectively reduce the weight of generator, cost performance is improved, the fan of generator has been changed to cast aluminium by previous steel plate welding
Manufacture.Fan and alternator shaft are by being interference fitted fixed position, together with generator high speed rotation.
Material density ratio iron is small, but quality is soft, not wear-resisting, and intensity is also inadequate, it is impossible to meet and directly coordinate rotation with shaft
The performance requirement turned.To solve these problems, it needs to research and develop a kind of bushing dress for improving fan rigging position wearability and intensity
It puts.
Invention content
The purpose of this utility model is to be to provide a kind of bushing device for improving fan wear intensity, using device in itself
Architectural characteristic reach promoted fan rigging position wear-resistant strength mesh.The utility model intensity is good, wearability is high, processing and manufacturing
Simply, performance is stablized, and does not influence generator electromagnetic performance, is particularly suitable for motor common currently on the market.
The utility model is achieved like this：
A kind of bushing device for improving fan wear intensity, it is characterised in that：Centrally disposed one of the bushing device
Through-hole, and set there are one notch；Round flange and convex moulding are surrounded by, convex moulding is equipped with mounting hole, and mounting hole is
Tapped through hole.In use, the bushing device is put into blower tray, mounting hole is passed through using bolt, wind is made by bolt
Fan is fixed with shaft；The convex moulding is stuck in blower tray, prevents from rotating；The round flange prevents bushing in fan branch
Play inside frame.
Preferably, the convex moulding is 4.
Preferably, the bushing device is additionally provided with removal hole, and removal hole is tapped blind hole.It, will if fan will be dismantled
Fan extracting tool coordinates with removal hole, fan can be dismantled from shaft, will not damage fan and shaft.
Preferably, the removal hole is 2.
Preferably, the roughness of centre bore and notch is 3.2, and dimensional accuracy is H8 grades.
Preferably, the material that the bushing device uses is 200 material of cast iron.
The beneficial effects of the utility model are：(1) wearability of fan rigging position is promoted notable；(2) stable structure and
Reliably；(3) it is easy to operate, it is highly practical.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the assembling schematic diagram of the utility model and blower tray.
In the figure 1, blower tray, 2, the bushing device of the utility model, 3, centre bore, 4, convex moulding, 5, round convex
Edge, 6, mounting hole, 7, notch, 8, removal hole.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the utility model is such to what is implemented, a kind of bushing device 2 for improving fan wear intensity is interior
Portion is equipped with centre bore 3 and notch 7, and side is surrounded by convex moulding 4, round flange 5, and end face is equipped with removal hole 8, convex moulding
4 are equipped with mounting hole 6.2 shape of bushing device is circle, and intermediate centre bore 3 is through-hole, and notch 7 is located at through-hole side.Semicircle
There are four flanges 4, vertical with round flange 5；One of 4 face notch 7 of convex moulding, and in one screw thread of circular arc side face drilling
Through-hole simultaneously passes through notch 7.Removal hole 8 is tapped blind hole, on end face.The material of bushing device 2 be cast iron 200, fan branch
Frame 1 is aluminium material, and the wearability of cast iron is much better than aluminum material, and wind can effectively be promoted by increasing cast iron liners device 2 in fan
Fan the wearability of rigging position.Round flange 5 and four convex mouldings 4 can effectively prevent bushing device under the effect of external force
It moves, bushing device is caused to come off.The notch 7 is Precision Machining position, by flat key and shaft, fan shelves clamping simultaneously
It is fixed.The convex moulding 4 is stuck in blower tray 1, prevents from rotating；The round flange 5 prevents bushing in blower tray 1
Portion's play.
When blower tray 1 is cast, blower tray 1 is formed according to the appearance profile of round flange 5 and four convex mouldings 4
Internal structure.After fan cast successfully, remove flash removed after, fan is taken to generator erecting yard.
As shown in Fig. 2, in use, bushing device 2 is put into specific fan mould, by the flat key of flat key loading shaft
In slot, the centre bore 3 of bushing device 2 passes through shaft, close fan shelves slowly, and the notch 7 of fan is aligned flat key in shaft
Position gently promotes, it is ensured that fan notch 7 is aligned flat key；Then fan mounting tool is gently tapped with copper rod, makes fan slowly
It is mobile, until fan end face withstand shaft step surface it is immovable until.Take out a set of hexagon-headed bolt, small washer and spring pad
Circle, is installed in mounting hole 6, ceaselessly rotates hexagon-headed bolt until encountering flat key in shaft, it is impossible to until screwing again, it is ensured that
Fan is fixed with shaft, is clamped.
If fan will be dismantled, fan extracting tool and removal hole 8 are coordinated, fan can be dismantled from shaft, no
Fan and shaft can be damaged.
