Connecting seat is equipped with, the lower bearing protective cover top is provided with upper bearing protective cover, and upper bearing protective cover passes through side
The fixing bolt in face is screwed onto on lower bearing protective cover, and the upper bearing protective cover pros are welded with draw ring, and top
Portion offers elastic hole, and the upper bearing protective cover and lower bearing protective cover front middle part are provided with input port, and rear
Delivery outlet is provided with, greasing hole is offered on the outside of the delivery outlet on protection board.
Preferably, the fixed seat base plate, upper bearing protective cover, lower bearing protective cover and connecting seat are high carbon chromium
Stainless steel making, and upper bearing protective cover and lower bearing protective cover are internally provided with sound absorbing layer, while sound absorbing layer is foaming
Elastomeric material is constituted.
Preferably, the greasing hole correspondence and internal bearings gap.
Preferably, the lower bearing protective cover and fixed seat base plate be to be integrally cast, and fixed seat base plate width
Width of the degree less than lower bearing protective cover.
Preferably, 45 ° of chamferings, and chamfer surface impulse- free robustness are provided with the input port and delivery outlet external interface.
Compared with prior art, the beneficial effects of the invention are as follows：The noise reduction bearing block, structure setting rationally, fix by bearing
Protection structure is fixed by fixing bolt, and dismounting is easy to use, while inside uses foam rubbery material, is can absorb and is rolled
The noise of bearing, improves working environment, and side is set using greasing hole, and lubricating grease can be added without dismounting, and easy maintenance is adopted
Set with elastic hole, bearing is carried out by bolt and is fixed, prevent bearing bob, uniform force increased the use of equipment
Life-span.
