They may also reduce shock loading and vibration. There are two main types of couplings:\u00a0 Rigid couplings and Flexible couplings. Rigid couplings are used for shafts having no misalignment while flexible couplings can absorb some amount of misalignment in the shafts to be connected.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-10452 size-full\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/Sleeve-coupling1-e1627803524332.jpg\" alt=\"What Is a Sleeve Coupling\" width=\"719\" height=\"356\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/Sleeve-coupling1-e1627803524332.jpg 719w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/Sleeve-coupling1-e1627803524332-300x149.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/Sleeve-coupling1-e1627803524332-696x345.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/Sleeve-coupling1-e1627803524332-324x160.jpg 324w\" sizes=\"(max-width: 719px) 100vw, 719px\" \/><\/p>\n<p>One of the simple types of rigid coupling is a sleeve coupling which consists of a cylindrical sleeve keyed to the shafts to be connected. It is made of cast iron. It consists of a hollow cylinder whose inner diameter is the same as that of the shaft (sleeve). It is fitted over the ends of the two shafts by means of a gib head key. The power is transmitted from one shaft to the other shaft by means of a key and a sleeve.<\/p>\n<p>In other words, a Sleeve coupling is a basic type of couplings including a pipe whose bore is finished to the required tolerance based on the shaft size. Based on the usage of the Sleeve Coupling a keyway is made in the bore in order to transmit the torque by means of the key. Two threaded holes are provided to lock the coupling in position.<\/p>\n<p>Sleeve couplings are known also as Box Couplings. In this case, shaft ends are coupled together and abutted against each other which are enveloped by muff or sleeve. A gib head sunk keys hold the two shafts and sleeves together.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Structure_Design_Working_Principle_of_Sleeve_Coupling\"><\/span>The Structure, Design &amp; Working Principle of Sleeve Coupling<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>So far, we are somewhat familiar with jaw couplings and know what they are basically used for. Let&#8217;s take a closer look at how jaw couplings work.<\/p>\n<p>The sleeve coupling transmits low to medium torque between connected equipment in shear through an elastomeric insert with male splines that mate with female hub splines.\u00a0 The insert material is typically EPDM, Neoprene, or Hytrel and the insert can be a one-or-two-piece design.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-10453\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/B2418-Splined-Sleeve-Coupling.png\" alt=\"What Is a Sleeve Coupling\" width=\"500\" height=\"323\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/B2418-Splined-Sleeve-Coupling.png 500w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/B2418-Splined-Sleeve-Coupling-300x194.png 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/p>\n<p>The muff or sleeve is made into two halves and is bolted together. The halves of the muff are made of cast iron. The shaft ends are made to butt each other. A single key is fitted directly in the keyways of both shafts. One-half of the muff is fixed from below and the other half is placed from above.<\/p>\n<p>Both halves are held together by means of mild steel studs or bolts and nuts. The number of bolts may be two, four, or six. The advantage of this coupling is that the position of the shafts need not be changed for assembling or disassembling of the couplings.<\/p>\n<p>In other words, in sleeve couplings, the shafts are taken and the keys are slid over them. Both the shafts along with the keys are then fitted into the sleeve. In this way, a sleeve coupling is assembled. In the following section, we will meet the advantages and disadvantages of the sleeve, muff, or as it is called box coupling.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Jaw_Coupling_Applications\"><\/span>Jaw Coupling Applications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Sleeve couplings are nothing but just a sort of thick hollow cylinder\/pipe called a sleeve or muff. The sleeve is manufactured keeping the diameter of the shaft in mind so that the shaft fits perfectly into the sleeve. The driver &amp; driven, both shafts are then inserted into each side of the sleeve. Also, two or more threaded holes are provided into the sleeve as well as in both of the shaft\u2019s ends so that they don\u2019t move in the longitudinal direction when the bolts are inserted into them. Also, the keyway and key ensure that the shaft and sleeve don\u2019t slip.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-10454\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/517ZCRPF0xL._SL1000_.jpg\" alt=\"What Is a Sleeve Coupling\" width=\"695\" height=\"597\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/517ZCRPF0xL._SL1000_.jpg 695w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/517ZCRPF0xL._SL1000_-300x258.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/517ZCRPF0xL._SL1000_-489x420.jpg 489w\" sizes=\"(max-width: 695px) 100vw, 695px\" \/><br \/>\nThe sleeve coupling is easy to manufacture as there are a few numbers of components.<\/p>\n<ul>\n<li>used where the shafts don\u2019t require any alignments and load capacity is light to medium duty.<\/li>\n<li>To transmit power from the driving shaft to the driven shaft.<\/li>\n<li>To connect or couple 2 components which are manufactured separately for example output motor shaft and generator.<\/li>\n<li>To introduce extra flexibility while transmitting power in case of space restrictions.<\/li>\n<li>To introduce protection against overloads.<\/li>\n<li>To reduce the transmission of shock loads from one shaft to another by using flexible couplings.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Advantages_Disadvantages_of_Sleeve_Couplings\"><\/span>Advantages &amp; Disadvantages of Sleeve Couplings<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Finally, we reach the last section of this article.
