两螺杆之间的配合间隙偏差评估数据

锥形异向双螺杆之间的配合间隙偏差评估数据，通过系统性地收集、分析，并与设计目标及规定允许偏差Δallow≤0.1mm等行业规范进行比对，为精确衡量螺杆的制造与装配精度是否达标提供了直接的量化证据。这些偏差数据是评估螺杆啮合区几何精度的核心指标，对制造商而言，是优化工艺、控制质量的关键输入。对于采购方，这些具体的偏差评估数据是判断所购螺杆或挤出设备制造质量、预期运行稳定性和耐久性的重要客观依据，直接影响其购买决策、议价能力以及对产品长期可靠性的预期；较小且符合标准的偏差值通常意味着更高的加工精度和更优的潜在性能。在设备或核心部件的流通与交易环节，公开、可验证的间隙偏差评估数据可以作为重要的质量凭证，提升产品的市场公信力、竞争力和实际交易价值，因为它客观揭示了关键部件的精密程度，减少交易双方的信息不对称，为二手设备评估或部件再销售提供价值参考，促进更透明和公平的交易。一、 数据采集 1.1 基础测量数据 进料段A侧实测间隙(mm)、进料段B侧实测间隙(mm) 塑化段A侧实测间隙(mm)、塑化段B侧实测间隙(mm) 挤出段A侧实测间隙(mm)、挤出段B侧实测间隙(mm) 进料段A侧设计间隙(mm)、进料段B侧设计间隙(mm) 塑化段A侧设计间隙(mm)、塑化段B侧设计间隙(mm) 挤出段A侧设计间隙(mm)、挤出段B侧设计间隙(mm) 1.2 技术标准阈值设置 标准允许的最大配合间隙偏差Δallow: 0.1mm 二、 核心计算公式 2.1 各测点间隙偏差(δ)计算 进料段A侧偏差 = |进料段A侧实测间隙 - 进料段A侧设计间隙| 进料段B侧偏差 = |进料段B侧实测间隙 - 进料段B侧设计间隙| 塑化段A侧偏差 = |塑化段A侧实测间隙 - 塑化段A侧设计间隙| 塑化段B侧偏差 = |塑化段B侧实测间隙 - 塑化段B侧设计间隙| 挤出段A侧偏差 = |挤出段A侧实测间隙 - 挤出段A侧设计间隙| 挤出段B侧偏差 = |挤出段B侧实测间隙 - 挤出段B侧设计间隙| 2.2 最大间隙偏差(Δm )计算 最大间隙偏差 Δm= max(进料段A侧偏差, 进料段B侧偏差, 塑化段A侧偏差, 塑化段B侧偏差, 挤出段A侧偏差, 挤出段B侧偏差) 2.3 偏差符合度(Rc）计算 偏差符合度 Rc= 最大间隙偏差Δm÷ 标准允许的最大配合间隙偏差Δallow 三、 质量判定规则 如果 R c≤0.5：判定结果：配合间隙 = 优秀； 如果 0.5<Rc≤0.8：判定结果：配合间隙 = 良好； 如果 0.8<Rc≤1.0：判定结果：配合间隙 = 合格； 如果 1.0<R c≤1.2：判定结果：配合间隙 = 预警 (不合格)； 如果 Rc>1.2：判定结果：配合间隙 = 严重不合格。Dataset for evaluating fitting clearance deviations between conical counter-rotating twin screws. This dataset, obtained through systematic collection and analysis and compared against industry specifications (including the allowable deviation Δallow ≤ 0.1 mm) and design targets, provides direct quantitative evidence for accurately judging whether the manufacturing and assembly accuracy of the screws meets the standards. These deviation data are core indicators for evaluating the geometric accuracy of the screw meshing zone. For manufacturers, they are key inputs for process optimization and quality control; for purchasers, these specific deviation evaluation data serve as important objective basis for judging the manufacturing quality of the purchased screws or extrusion equipment, as well as their expected operational stability and durability, directly affecting their purchasing decisions, bargaining power and expectations of long-term product reliability. Smaller deviation values that comply with standards usually indicate higher machining accuracy and better potential performance. In the circulation and transaction links of equipment or core components, publicly verifiable clearance deviation evaluation data can serve as important quality certificates, enhancing the market credibility, competitiveness and actual transaction value of products. This is because it objectively reveals the precision of key components, reduces information asymmetry between transaction parties, provides value references for second-hand equipment evaluation or component resale, and promotes more transparent and fair transactions. 1.

Quality Judgment Rules If Rc ≤ 0.5: Judgment result: Fitting clearance = Excellent; If 0.5 < Rc ≤ 0.8: Judgment result: Fitting clearance = Good; If 0.8 < Rc ≤ 1.0: Judgment result: Fitting clearance = Qualified; If 1.0 < Rc ≤ 1.2: Judgment result: Fitting clearance = Warning (Unqualified); If Rc > 1.2: Judgment result: Fitting clearance = Seriously Unqualified.
