Lubricated Joint Clearance Essay
Investigation of Effect of Lubricated Joint Clearance on Vibration of Four bar Mechanism Bhagyesh B. Kasale Milind S. Kirkire 1Department of Mechanical Engineering 2Assistant Professor , Finolex academy of management and technology, Finolex academy of management and technology, Ratnagiri-415639,Maharashtra,india Ratnagiri-415639,Maharashtra,india shreebhagyesh@gmail.com milind.kirkire@gmail.com Abstract - A mechanism is a device designed to transform input forces and movement into a desired set of output forces and movement. Mechanisms are widely used in many industries such as automobile. Clearances in mechanism are unavoidable due to assemblage, manufacturing errors and wear. Moreover, the clearance occurs in each joint with the movement of mechanism. The movement of the real mechanisms varies from an ideal mechanism and accuracy of motion gets decreased due to clearances in joints. Also the existence of clearance in …show more content…
The plan of the experiment was developed to assess the effect of operating speed and clearance on the vibrations in the joint. After analysing the vibrations in dry contact, lubrication is provided in the joints. Now the same experiment is conducted for same operating conditions and clearance and vibrations are measured. The results for both the conditions i.e. with dry and lubricated conditions are compared. Fig. 4 shows the comparison of vibrations in the joint with dry contact and with lubricated contact with speed 50 rpm and 0.1mm clearance. Fig.5 shows the comparison of vibrations in the joint with dry and with lubricated contact with speed 70 rpm and 0.1mm clearance. Fig. 6 shows the comparison of vibrations in the joint with dry and with lubricated contact with speed 50 rpm and 0.5mm clearance. Fig. 7 shows the comparison of vibrations in the joint with dry and with lubricated contact with speed 70 rpm and 0.5mm

2403 Words | 10 PagesThe measured tensions were normalized relative to the maximum tension and the lengths were normalized relative to the length at which maximum force was generated (Ln = 29 mm). The measured data and expected data were plotted together (Figure 3). Correlation between measured and expected tensions at the same normalized lengths was determined for the three expected segments of the length-tension relationship.2,3,4 This was done using piecewise linear regression and yielded r2isometric = 0.956033. The fitted curve for the isotonic experiment resulted in r2isotonic = 0.960557. The F0 was 19.5 N for the fit and 6.35 N for the guess.

This frame of reference is based in the desire to explain function anatomically and physiologically and it assumes successful human motor activity is based of physical mobility and strength and participation in activity involving repeated specific graded movements that maintains and improves function. Besides, it also assumes activity can be graded gradually to meet particular demands within an intervention programme. According to the biomechanical frame of reference, physical function can be promoted by using media and equipment to promote physical function in which it can be applied to a variety of creative and constructive activities and use specific techniques for measuring movements, strength and
