bolt torque
解釋
螺栓啟動力矩-
Abstract : by means of metallographical examination and sem, the microstructure characteristics, macro - and microfractographs of the brittle broken wheel hull bolt of bj212 automobile have been studied. the results show that the thin - headed screw, with excessively deep carbonitriding layer and hardening layer, has less resistance to brittle fracture in the thin area of its head. at the root of the head connecting the stem, a tensile stress may emerge owing to the non - even quenching stress. those are the two reasons for low torque fracture of bolt
文摘:藉助金相、掃描電鏡等手段對低扭矩脆斷的bj212汽車輪殼螺栓的金相組織特徵，宏觀和微觀斷口形貌等進行了研究，結果表明：這種頭部薄的螺栓，滲層和淬透層過深，使頭部薄區脆斷抗力降低，在頭部與桿的根部，由於淬火應力不均勻導致根部產生拉應力，均是導致螺栓低扭矩斷裂的原因。 -
Using the optimum calculating method, some important technical parameters could be determined, that is, optimum supporting force, allowable deformation of rock mass, cross section area of u - shape set, pre - tight force and diameter of the bolt as well as torque to provide optimum supporting force
用這一計算方法能求出巖石恆阻支護的重要技術參數，即最優（小）恆阻支護力、圍巖最大允許變形量、恆阻u型鋼支架的截面積、聯接螺栓的預緊力和直徑及最優支護力的擰緊力矩。 -
Combines with a concrete subject, this paper, composed of seven chapers, makes a deep analysis on theory and experiment of key bolt fastening of engine. the first chapter presents the theory of tightening technology of the available bolt the second chapter gives a narrating about tighten technology availably in survey. pointing that the nature of torque control is axis preload
本文結合一具體課題，第一章敘述了可控螺栓擰緊技術的理論，第二章綜述了可控擰緊技術，提出了扭矩控制研究的實質是控制螺栓的軸向預緊力。 -
Chapter three makes clear the importance of preload, and deals with the theories on the relationship between preload and torque, angle and extension of the bolt from various aspects
第三章由扭矩控制的實質? ?預緊力，點明了預緊力的重要性，預緊力與擰緊力矩、螺母轉角、螺栓伸長的關系，對其進行了理論方面的研究和探討。 -
The joint surface normal stress is worked out and then the minimum sleeve press - in force, by which tightening bolt number is determined, ensuring that the sleeve is fastened and the desired torque is delivered
根據結合面的壓強計算了壓入襯套所需的最小壓入力，並依此確定緊固螺釘的數量，以確保壓牢襯套，滿足傳遞扭矩的需要。 -
Commonly, if slide between joint bar and rail is permitted, the bolt torque ranged from 500n - m to 700n - m is suitable. if the joint is " frozen ", the bolt torque should range from 900n - m to 1100n - m
一般來說，如果允許夾板與鋼軌相互滑動，接頭扭矩500 700n ? m范圍是適宜的；如果將接頭「凍結」 ，則螺栓扭矩應在900 1000n ? m左右。
