In corresponding round table-like, the former is by studs and is sleeved on double for the interlude of studs and the inner wall of transition tapered sleeve
The transition tapered sleeve of header stud interlude is connected with flange, and nut and washer are mounted on studs both ends, on cylinder excircle
Around the reinforcing ring for being welded with several parallel interval arrangements, the dovetail groove for clamping friction lining is equipped on the reinforcing ring,
Friction lining is fastened on cylinder by dovetail groove, is connected with NOL ring on the former of manhole outer rim.
To guarantee friction pulley to the support strength of wirerope and external applied load, the adjacent reinforcing ring is connected by connecting plate.
To realize, quickly peace is torn open, and the both ends of the studs use the screw thread of positive and negative bidirectional arrangements.
For convenience of bit transitions tapered sleeve and increase rubbing action point contact area, the washer uses stop washer.
The oil filler point for being connected to its end face and intermediate periphery is equipped in the studs.
Compared with prior art, the utility model has the advantage that
1, interior supporting plate is replaced by external reinforcing ring, inner barrel welding workload, stress under case of heavy load can be reduced
It is distributed, and barrel distortion amount is small, bearing capacity is stronger.
2, using the dovetail groove installation fixed friction liner on reinforcing ring, cancellation fixed block, briquetting and conjunction bolt, in cylinder
Bolt hole is removed in the effective workspace of body, substantially improves structure of friction wheel, and the stress for eliminating original bolt hole is concentrated.
3, cooperated by the studs of compound coupling assembly and transition tapered sleeve, main shaft and friction pulley are being promoted into load production
Raw torque is divided into shearing force and the transmitting of frictional force two parts, realizes the shearing pair of main shaft and friction pulley and secondary answer of rubbing
Superposition connection is closed, under same transmitting moment loading, studs requirement is substantially reduced, to make on flange and former
Mounting hole processing quantity, the I& M amount of compound coupling assembly all accordingly reduce, improve work efficiency, reduce plus
Work cost.
4, increase NOL ring on former, improve former stress condition, so as to cancel lateral pull rod between former, make
Former affranchises elastomer, and the stress of former is avoided excessively to concentrate, and reduces the probability that inequality deformation occurs in cylinder.
The utility model structure is simple, and uniformly, stress distribution is good, and bearing capacity is strong for deformation, and transmitting torque is big, safely may be used
It leans on, can satisfy the requirement of deep-well big load promotion.
