Hydraulic Breaker Through Bolt Stress
The tightening torque of each hydraulic breaker through bolt is T=2 500N·m, the bolt head thread specification is M42 ×4 mm, the maximum oil pressure during hydraulic hammer operation is p1=16 MPa, and the maximum expansion pressure of nitrogen gas chamber is p2=2 MPa.
Hydraulic Breaker Through Bolt Preload force calculation
It is known that the hydraulic breaker through bolt tightening torque is T=2 500 N·m, the bolt head thread size is M42 × 4 mm, and the empirical formula T≈0.2 ×Qp ×d, the pre-tightening force is Qp=298 kN.
