Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.
As shown in Figure 1, hot press composite direction altering roller of the invention includes: drum shaft 1, roller tube 2, wearing layer 3, bearing
4 and 5, bearing block 6 and 7, bonded adhesives 8.
Drum shaft 1 determines, material selection 45# steel, bearing capacity for carrying roller tube 2 according to roller bearing capacity size
The drum shaft of biggish special roller choosing also wants Tempering and Quenching.The both ends of drum shaft 1 are separately fixed at the axis in bearing block 6,7
It holds on 4,5.The design of bearing block 6,7 is determined according to different belt widths, length conveying material bearing capacity size, can basis
