Abstract
The utility model discloses an engine fan belt idler. The engine fan belt idler comprises a fixed frame, a tensioning screw and a tensioning wheel, wherein the fixed frame comprises an undersurface, a front side surface, a back side surface and a right side surface; mounting holes are formed in the undersurface; a sliding chute is formed in the right side surface; mounting holes are formed in the back side surface; the tensioning screw is mounted in one of the mounting holes in an inserting manner; the tensioning wheel is mounted on the outer side of the sliding chute; one end of the fixing shaft of the tensioning wheel penetrates through the sliding chute and is movably positioned in the sliding chute; a screw hole is formed in the shaft head of the fixing shaft; the threads of the tensioning screw are screwed into the screw hole; the fixed frame is formed through one-time casting and forming; the front side surface, the back side surface and the right side surface which are arranged on the fixed frame are connected to the undersurface in a casting manner; the sides of the front side surface and the back side surface are connected to the side of the right side surface in a casting manner; an arc-shaped connecting edge is casted on the inner side of each connecting surface. According to the utility model, the technical scheme is adopted, so that workpieces are neat in appearance; the arc-shaped connecting edges are casted on the inner sides of the connecting surfaces, so that the sides of the workpieces are connected more firmly, the mechanical strength of the workpieces is strengthened, and the mechanical fatigue resistance property is greatly improved.
Description
Technical field
The utility model belongs to engine fittings technical field, relates to a kind of engine blower tension pulley.
Background technique
At present, engine blower tension pulley is by fixed frame, tensioning screw and Idle wheel form, fixed frame is by bottom surface, leading flank, trailing flank and right flank form, on bottom surface, have mounting hole, on right flank, have chute, on trailing flank, have mounting hole, in hole, be fitted with tensioning screw, on the outer side surface of chute, Idle wheel is installed, stationary axle one end of Idle wheel is through chute, activity orientation is in chute, on the spindle nose of stationary axle, have screw, the screw thread of tensioning screw is screwed in this screw, its right flank and bottom surface are made by a block plate material heat treatment bending, leading flank and trailing flank are welded on bottom surface and right flank with electric welding.The engine blower tension pulley of this structure, when heat treatment flanging, damage the mechanical strength of steel plate, when leading flank and trailing flank welding, exist crator not of uniform size, welding position cannot the neat problem of standard, and the engine blower tension pulley of this structure exists the problem of the poor performance of bad mechanical strength, anti-mechanical fatigue in use.
Summary of the invention
For solving the right flank of engine blower tension pulley fixed frame in prior art, adopt hot flanging to process, leading flank and trailing flank adopt soldering, there is workpiece apparent size irregularity, bad mechanical strength, the poor problem of anti-mechanical fatigue performance of train, the utility model provides a kind of engine blower tension pulley, by fixed frame, tensioning screw and Idle wheel form, fixed frame is by bottom surface, leading flank, trailing flank and right flank form, on bottom surface, have mounting hole, on right flank, have chute, on trailing flank, have mounting hole, in mounting hole, be fitted with tensioning screw, Idle wheel is arranged on the outer side surface of chute, stationary axle one end of Idle wheel is through chute, activity orientation is in chute, on the spindle nose of stationary axle, have screw, the screw thread of tensioning screw is screwed in this screw, casting forming of fixed frame, leading flank on fixed frame, trailing flank and right flank casting are connected on bottom surface, the side casting of leading flank and trailing flank is connected on the side of right flank, in the inner side of each junction surface, be cast with curved fillet.
Adopt after technical solutions of the utility model, due to right flank, leading flank and a cast molding of trailing flank, the apparent size of workpiece is regular, arc fillet in the casting of the inner side of each junction surface makes the connection on each limit of workpiece more firm, the overall mechanical strength of workpiece is forced, anti-mechanical fatigue performance of train significantly improves, and greatly extend working life.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation described in the utility model.
