Abstract
The utility model discloses a special connecting device for a large-diameter combined type gear ring. The special connecting device comprises an upper connecting pin and a lower connecting pin which are inserted into an upper connecting hole and a lower connecting hole of butted port spokes of two adjacent gear ring sections, wherein fastening connecting holes are perpendicularly and symmetrically formed between the upper connecting pin and the lower connecting pin which are located on spokes of the two gear ring sections respectively, and wedge-shaped iron gaskets and wedge-shaped bolts are arranged in the fastening connecting holes in parallel; and L-shaped iron gaskets are arranged below anti-loosening nuts screwed on the wedge-shaped bolts, short edges of the L-shaped iron gaskets are buckled and pressed on the upper surfaces of the wedge-shaped iron gaskets, and long edges extend to the surface of the spokes of the gear ring sections. The special connecting device for the large-diameter combined type gear ring has the advantages of simple structure, safety and reliability of connection, low probability of cracking and convenience in mounting and dismounting; and the combined gear ring adopting the special connecting device can adapt to and bear variable load circulating load of long-term starting and parking, and cannot cause butted port cracking.
Description
Technical field
The utility model relates to coupling arrangement, especially relates to the special coupling arrangement of a kind of large diameter combined gear ring.
Background technique
In cement plant and metallurgical and mining machinery, the ore mill that rotary kiln, rotary drum drying machine, edge drive etc. is all the large-scale involute cylindrical gear that adopts open type, and gear diameter can reach 5～12 meters of left and right.Consider to manufacture, transport and the convenience of installing, in the time of Design and manufacture gear ring, be stitched together after gear ring can being divided into two sections or four sections of processing.When segmented gear ring splicing at present, the bolts that adopt connect more, can have in various degree the problem of gear ring section counterpart cracking in using process.Even so Gear Processing precision is high again, if counterpart cracking also can destroy the meshing performance of gear, thereby affect service life of gear.How gear ring section counterpart being carried out to effective, reliable, fastening connection, is to ensure quantity-produced key.
Summary of the invention
The purpose of this utility model is to provide a kind of special coupling arrangement of large diameter combined gear ring that can solve gear ring counterpart problem of Cracking.
For achieving the above object, the utility model can be taked following technical proposals:
The special coupling arrangement of large diameter combined gear ring described in the utility model, comprise the upper and lower coupling bar being inserted in the upper and lower attachment hole of adjacent two gear ring section counterpart spoke, lay respectively on two gear ring section spokes up and down between coupling bar vertical symmetry offer and be fastenedly connected hole, described in be fastenedly connected and in hole, be set side by side with wedge shape parallels and wedge bolt; The lock nut below being screwed on described wedge bolt is provided with L shaped parallels, and the minor face of described L shaped parallels is withheld at described wedge shape pad upper surface, and long limit extends to gear ring section spoke surface.
The mating face gradient of described wedge shape parallels and wedge bolt is consistent.
The described aperture that is fastenedly connected hole is greater than the aperture of the upper and lower attachment hole of offering on gear ring section counterpart spoke.
The utility model has the advantage of simple in structure, connect safe and reliable, not easy to crack, be convenient to installation and removal.Tighten by upper and lower coupling bar and two gear ring section spokes the cross form linkage structure that wedge shape pad in attachment hole and wedge bolt form, mutual fastening transmitted load, wedge bolt has very strong self-locking and anti-loose ability, be used in conjunction with wedge shape parallels, the shear resistance of wedge bolt can be increased, the coupling bar resistance to tension balance in gear ring section counterpart spoke attachment hole can be made again.The combined type gear ring that adopts the utility model to connect can adapt to and bear the variable load cyclic load that long-term startup is stopped, and can not cause counterpart cracking.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that Fig. 1 I-I is to sectional view.
Embodiment
As shown in Figure 1, 2, gear ring section A and gear ring section B are two sections of gear rings to be connected, and the spoke of gear ring is T-Type structure, on the counterpart spoke 1 of gear ring section A and gear ring section B, offer upper and lower attachment hole.The special coupling arrangement of large diameter combined gear ring described in the utility model, comprise respectively and being inserted into, upper coupling bar 2 in lower attachment hole and lower coupling bar 3, upper coupling bar and 2 times coupling bars 3 support spoke 4 along it respectively and extend to gear ring section A and the gear ring section B of both sides, to support spoke 4 clamps wherein, laying respectively at gear ring section A and gear ring section B supports between upper coupling bar 1 on spoke 4 and lower coupling bar 2 vertical symmetry and offers and be fastenedly connected hole, being fastenedly connected hole runs through upper and lower coupling bar and supports spoke, in hole, be set side by side with wedge shape parallels 5 and wedge bolt 6 being fastenedly connected, the mating face gradient of wedge shape parallels 5 and wedge bolt 6 is consistent, lock nut 7 belows that are screwed on wedge bolt 6 are provided with L shaped parallels 8, and the minor face of L shaped parallels 8 is withheld at wedge shape parallels 5 upper surfaces, and long limit extends to the surface of counterpart spoke 1.Adjust for ease of installing, prevent counterpart cracking, the aperture that is fastenedly connected hole that supplies wedge shape parallels 5 and wedge bolt 6 to penetrate will be a bit larger tham the aperture of the upper and lower attachment hole penetrating for coupling bar of offering on two gear ring section counterpart spokes.
Working principle of the present utility model is as follows:
Gear ring section A and gear ring section B counterpart are arranged, for improving join strength, in the upper and lower attachment hole that heat treated upper coupling bar 2 and lower coupling bar 3 are offered from counterpart spoke 1 respectively, penetrate, form cross form locking mechanism with the wedge shape parallels 5 of both sides together with wedge bolt 6, two gear ring section counterparts are tightened together firmly, mutually transmitted load between fastening piece.Wedge bolt 6 has very strong self-locking and anti-loose ability, has added wedge shape parallels 5, can increase the shear resistance of wedge bolt 6, can make again the resistance to tension balance of coupling bar 2 and lower coupling bar 3 in gear ring counterpart place.This counterpart connecting structure can adapt to and bear gear ring and start for a long time the variable load cyclic load of parking, can there is not any cracking in gear ring counterpart, gear ring, in operation process, remains good meshing performance, can greatly improve working life and the safety reliability of gear ring.
