Abstract
The utility model relates to a low-noise wear-resisting gear for a pulverizing mill, which is composed of a gear ring and a wheel boss. The gear ring is made of hard, wear-resisting and organic materials. The gear ring and a metallic wheel boss are processed and formed into a gear. A plurality of stop dowels, or convex and annular position blocks, or concave and annular positioning slots or positioning slots which are provided with left screw and right screw are arranged at the region where the wheel boss is connected with the gear ring. The gear ring of the gear is made of non-metal materials. The transmission noise of the gear is obvious reduced. Therefore, the pollution of environmental noise is reduced. In addition, the driving gear can still run normally under the condition of frequent changes in load or even instant overload due to heavy load. The phenomenon of teeth breaking can not happen. Therefore, the utility model has the advantage of long service life.
Description
The utility model shows a kind of low noise wear-resistant gear that is applied to flour mill.
At present, be widely used in two roll drives on the flour mill, commonly used have two kinds of forms, and a kind of is cast iron gear, and another is a synchronous pulley.The former has been since flour mill comes out, generally adopt in order to reduce production costs, but because in use the flour mill roll seam need constantly be adjusted, and gear meshing gap and length of action also constantly change thereupon, strength of gear changes greatly, the frequent broken teeth of gear, and its transmission noise is too big.In order to reduce the transmission noise, after adopted the design of synchronous pulley again, need increase corresponding tensioning apparatus, therefore increased material consumption, prolonged machining period, thereby improved equipment cost.
The deficiency that the utility model exists at above-mentioned roll drive, the structural design of improvement drive is with new material and corresponding process technology, provide a kind of processing simple, easy to use, dependable performance, the wear-resistant travelling gear of flour mill low noise that operates steadily.
Flour mill low noise wear-resistant gear is made up of gear ring and wheel hub, and gear ring system adopts hard, wear-resisting organic material, with metal wheel hub machine-shaping gear.For preventing gear ring and the unexpected loosening slippage of wheel hub appearance in the use, with the gear ring connecting portion, also can adopt other to reinforce locate mode on the wheel hub, as some shop bolts being set at wheel hub periphery connecting portion; Or convex circular orientation piece, or concavity annular positioning groove, and several concavity locating slots axially are set along circumferential wall; Or be processed with left and right spiral positioning groove respectively.
The gear ring of gear can adopt hard, wear-resisting engineering plastics, or industrial nylon and cast iron wheel hub heat notes or cast molding.The concrete locate mode of reinforcing of other of wheel hub and gear ring connecting portion comprises along even distribution of middle circle perisporium several shop bolts are set; Also can make the middle part circumferential wall be processed into convex ring shaped axial locating piece, and the circumferential locating slot of several concavities axially is set along circumferential wall; Or make the middle part circumferential wall be processed into concavity ring shaped axial locating slot, and the circumferential locating slot of several concavities axially is set along circumferential wall; Perhaps extremely middle at wheel hub and gear ring connecting portion two ends, process left-hand screw locating slot and right-hand screw locating slot respectively along circumferential wall.
Flour mill roll travelling gear gear ring adopts nonmetallic materials, and its transmission noise obviously reduces, and has reduced the environmental noise pollution.In addition, this travelling gear is frequent in load variations, even under the instantaneous heavily loaded event of overload, still can run well, and the broken teeth phenomenon can not take place, thereby prolong service life, and economical, societal benefits are remarkable.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an I type structural representation of the present utility model
Fig. 2 is an II type structural representation of the present utility model
Fig. 3 is an III type structural representation of the present utility model
Fig. 4 is an IV type structural representation of the present utility model
Introduce embodiment of the present utility model below in conjunction with accompanying drawing:
This flour mill low noise wear-resistant gear is made up of gear ring (1) and wheel hub (2), gear ring (1) adopts hard, wear-resisting engineering plastics, or industrial nylon material, annotate with cast iron wheel hub (2) heat or gear is made in the casting one-shot forming, also can carry out a small amount of machining and satisfy instructions for use and get final product.For preventing that gear ring (1) unexpected loosening slippage occurs with wheel hub (2) in the use, wheel hub (2) is gone up and the connecting portion of gear ring (1), other has adopted following four kinds to reinforce locate mode: as shown in Figure 1, can evenly distribute along wheel hub (2) middle circle perisporium is provided with several shop bolts (3) reinforcing; Shown in Figure 2, be processed into convex ring shaped axial locating piece for making wheel hub (2) middle part circumferential wall, and the circumferential locating slot of several concavities axially be set along circumferential wall; Shown in Figure 3, be processed into concavity ring shaped axial locating slot for making wheel hub (2) middle part circumferential wall, and the circumferential locating slot of several concavities axially be set along circumferential wall; Shown in Figure 4, extremely middle for wheel hub (2) and gear (1) connecting portion two ends, process left-hand screw locating slot and right-hand screw locating slot respectively along circumferential wall.
