Note :Strike out whichever is not applicable Title of invention Frictional resistance of roller as a linear position feed back device and to convert rotary motion into linear motion. Field of invention Field of invention relates to the device for linear position feed back of linear distance traveled by table and to convert rotary motion of motor into linear movement of table in machine tools. Objective of invention The objective of invention is to use frictional resistance of roller as a linear position feed back device and to convert rotary motion of motor into linear movement of table in machine tools or for any other purpose. Background of known art In prior art linear glass scales with scanner unit is used as a linear position feed back device and ball screws are used to covert rotary motion of motor into linear motion of table in machine tools. Summary of invention Frictional resistance of roller as a linear position feed back device and to convert rotary motion into linear motion works on frictional resistance of roller consisting of rollers, friction plate, and spring. The friction plate is placed between two rollers. One roller pushes friction plate against the other roller with spring force. When the friction plate is made to move linearly the roller which is connected to encoder rotates due to frictional resistance. The encoder converts rotary motion into linear distance traveled by the table. To convert rotary motion of motor into linear motion of table, the motor B placed in place of encoder. When the motor rotates the friction plate moves moving the table. Due to the frictional resistance between friction plate and rollers caused by spring force, Brief description of drawing According to this invention frictional resistance of roller as a linear position feed back device and to convert rotary motion into linear motion comprising of rollers supported by bearings in the housing. The friction plate is fixed to the table. The friction plate is placed between rollers. One of the housing is fixed to base and the other housing placed on guide rods with springs. Brief description of invention with reference to drawing As shown in fig-1. The roller (1) is supported by bearings (7) in the housing (6) and the roller (1) is connected to encoder (12). The housing (6) is fixed to the base. The roller (2) is supported by bearings (8) in the housing (9). The housing (9) is mounted on guide rods (11) with spring force (10) acting on it which pushes friction plate (3) againstroller (1). The friction plate (3) is fixed to table (4) by bracket (5). When the friction plate (3 ) moves linearly by table (4) movement. The roller (1 ) rotates due to frictional resistance caused by spring (10) force .The roller (1) which is connected to encoder (12) also rotates. The encoder (12) in combination with electronic system converts rotary motion into linear distance traveled by table. There fore the frictional resistance must always be greater than the force required to rotate encoder (12) and rollers (1&2). To convert rotary motion of motor into linear motion of table (4). The motor is mounted in place of encoder (12). When the motor is made to rotate the rollers (1&2) rotate. So the friction plate (3) moves linearly, Due to the frictional resistance between rollers and friction plate caused by spring (10) force. The friction plate (3) which is fixed to table (4) by bracket(5) moves the table (4) linearly. There fore the frictional resistance must always be greater than the force required to move the table (4). To increase frictional resistance in place of spring force various methods can be used like hydraulic force and by providing knurling on friction plate and rollers. Claims 1) As shown in fig-1. The roller (1) is supported by bearings (7) in the housing (6) and the roller (1) is connected to encoder (12). The housing (6) is fixed to the base. The roller (2) is supported by bearings (8) in the housing (9). The housing (9) is mounted on guide rods (11) with spring force (10) acting on it which pushes friction plate (3) against roller (1). The friction plate (3) is fixed to table (4) by bracket (5). 2) As claimed in claim 1, when the friction plate (3) moves linearly by table (4) movement. The roller (1) rotates due to frictional resistance caused by spring (10) force. The roller (1) which is connected to encoder (12) also rotates. The encoder (12) in combination with electronic system converts rotary motion into linear distance traveled by table. There fore the frictional must always be greater than the force required to rotate encoder (12) and rollers (1&2). 3) As claimed in claim 1, to convert rotary motion of motor into linear motion of table (4). The motor is mounted in place of encoder (12). When the motor is made to rotate the rollers (1&2) rotate. So the friction plate (3) moves linearly, Due to the frictional resistance between rollers and friction plate caused by spring (10) force. The friction plate (3) which is fixed to table (4) by bracket (5) moves the table (4) linearly. There fore the frictional resistance must always be greater than the force required to move the table (4). 4) To increase frictional resistance in place of spring force various methods can be used like hydraulic force and by providing knurling on friction plate and rollers. 4) As claimed in claim 1 to 4 are described in with respect to accompanying drawing.
