design stage can substantially reduce development costs. Then: 1) Multiply speed x working angle . How to determine Universal Joint angular torque capacity Peak torque values apply only when the working angle is zero. . . Describe the various gear types and their effect on speed, torque and direction of rotation. 2. Ae = U A A = Ag = 4 x 3/8 = 1.5 in 2 - See Spec. Tension fracture of the member governs. PART DESIGN & ASSEMBLY (UNIVERSAL JOINT) From this diagram we have to know, Selection of plane Sketching the line and circle Constrain the dimension Symmetricity Mirror line object Trim the profile Exit work bench Pad the profile Pocket Project element Edge fillet The figure N°1 show the involute curve generation with the most important elements. A double D shaft has two flats on the shaft that correspond to the female end of the u-joint. The end returns at the corners were not included in the calculations… This universal driveline, how-ever, must then incorporate an intermediate bearing. B3 U = 0.75 , since connection length (Lconn) < 1.5 w - See Spec. Here, U Fig- 2 Universal Joints One universal joint is used to connect the transmission main shaft and the propeller shaft, other universal joint is used to connect the other end of the propeller shaft and the differential pinion shaft. design calculations is permitted for weld reinforcement. a single joint if it were to replace the entire driveline. The effective throat shall be the shortest distance from the joint root to the weld face of the diagrammatic weld (see Annex I). Universal joint (U-joint) 14 Worm gear 6 KEY TERMS After studying this chapter, the reader should be able to: 1. Torque Calculations Calculating Maximum Driveshaft Torque for Export Applications Step 1 - Low Gear Torque Calculation LGT = T x TLGR x TE x SR x TCR x C Step 2 - Overall Low Gear Ratio Calculation OLGR = TLGR x SR x TCR Step 3 - Driveline Series Selection To select a driveline series: 1. The most important are: • Cantilever snap joints The load here is mainly flexural. 1.11 Algorithm for computing the columns of the Jacobian from the free modes of the joints. 22 1.6 Joint model formulas for higher-degree-of-freedom lower pair joints, universal joint, rolling contact joint, and 6-DOF joint, with abbreviations c θ i:= cosθ i and s θ i:= sinθ i. connection between them is made by the universal coupling. This calculation takes into account dynamic loading at the joint bearings. 2.4 Fillet Welds 2.4.1 Effective Throat 2.4.1.1 Calculation. Groove weld sizes for welds in T-, Y-, and K-connections in tubular members are shown in Table 3.6. • U-shaped snap joints A variation of the cantilever type. B3 Therefore, φ Rn = 54.8 kips The design strength of the member-connection system = 54.8 kips. ∗The Euler angles α i, β i, and γ Formulas for gear calculation – external gears Contents: Relationship between the involute elements ... to design a gear tooth profile which rolls through the mesh without friction. 3.3 Universal driveline with more than two joints Design requirements might dictate the use of a universal driveline that employs more than 2 joints. 4. In the following, the many design possibili-ties have been reduced to a few basic shapes. Here, also, the condition applies: U Res 0,0027. Approval of the thesis: THEORETICAL AND EXPERIMENTAL ANALYSES OF COMPLIANT UNIVERSAL JOINT submitted by ÇA ĞIL MERVE TANIK in partial fulfillment of the requirements for the degree of Master of Science in Mechanical Engineering Department, Middle East Technical University by, … Calculation principles have been derived for these basic designs. . . To strengthen the connection of the DD joint to the shaft, you can drill a dimple on the steering shaft for the set screw to clamp to. To determine angular operating torque, determine application speed, torque and operating angle. For example: the 3/4-inch measurement on a double D shaft is measured across the rounded portion of the shaft. . Define torque, and explain the relationship between torque and horsepower. . 3. Explain gear ratios and their effect on vehicle operation.
