HYDRAULIC BEARING PULLER- Mechanical Engineering Project


HYDRAULIC BEARING PULLER

SYNOPSIS
This report deals with design and fabrications of bearing puller with the help of hydraulic operations. A “hydraulic operated bearing puller” is a device which is used to remove the bearing from shaft by using the puller setup from supporting device. In the machines the press fit operations are very complicated to align the assembly. For this type of operations we need heavy force for assembling and disassembling the bearings from the machines. It can widely be used. It is easy to fit on the bearing and removing. This can be effectively used for removing the bearings.

WORKING PRINCIPLE
This device is working by the principle of hydraulic lifting system. In this project we use hydraulic bottle jack. Jack is fixed with the table in the area allocated to it. A handle is attached with the hydraulic jack. When the handle is pressed the oil in the hydraulic jack is allowed to flow which helps to actuate the jack. The rod in the jack comes up during this process. A pressure relief valve is attached to side of the bottle jack which helps rod to come back to its previous position. The bearing puller is attached to rod and the pulling end of the bearing puller is attached to the bearing. When the jack is operated the bearing puller goes upwards and so the bearing is pulled out of the shaft.

ADVANTAGES
  1. Low cost
  2. Saves the Man Power
  3. Saves the time
DISADVANTAGES
  1. Manually operated
  2. It cannot be kept upside down since it leads to leakage of oil
APPLICATION
Hydraulic bearing puller is used in industrial application and also for automobile works.
