Embodiment.
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figures 1 to 6, a kind of underwater shaft bearing structure for screw sand washer described in the utility model, comprise parts 1 under water, described parts under water 1 are by flange plate 12 and be separately fixed at the axle 11 of flange plate 12 both sides and annular support 13 forms, described axle 11 is set with axle sleeve 2, be set with outside described axle sleeve 2 and support steel bushing 3, by fastening piece 5, end cap 4 is installed away from flange plate 12 one end at support steel bushing 3.Adopt the technical program, in the working life of the equipment that substantially prolongs bearing under water under operating conditions and service condition, extend the repair cycle of bearing under water simultaneously, reduce recondition expense, efficiently solve the problem of bearing frequent breakage under water.
Described axle 11 is provided with positioning step 14 near flange plate 12 one end.Positioning step is used for positioning axle sleeve 2, prevents axle sleeve 2 from axle 11, producing vibration and affect its sealing.
Two equal sized by described axle sleeve 2 snugly fit on axle 11.Like this, axle sleeve 2 being served as bearing and use, traditional rolling friction is become sliding friction, thus increase the area of contact of axle and bearing, reducing damaging because rubbing excessive of bearing.
One end that described support steel bushing 3 is connected with end cap 4 is evenly distributed with some end cap fixed holes 31, end cap 4 is provided with the through hole matched with end cap fixed hole 31, in use, by fastening piece 5, end cap 4 is fixed on support steel bushing 3, thus axle sleeve 2 is locked on axle 11, in the technical program, fastening piece 5 is directly with bolts, and assembly and disassembly is convenient and swift.
