Abstract
The utility model belongs to the technical field of mechanical drive accessory, relating in specific to a belt driving tension pulley, which resolves the difficulty in installation of tension pulley in prior art where special loading and unloading tools are required and the kinetic friction of each element is obvious thereby the service life of tension pulley is reduced. The belt driving tension pulley comprises a contact wheel fixed on a rotating shaft by a bearing. The bearing is positioned on the lower end of a connecting plate; the connecting plate takes a circular shape on the upper end, on which a shaft sleeve is provided in the central position; the shaft sleeve is arranged with a dead axle internally and with a torsion spring externally; the dead axle and one end of the torsion spring are fixed on a spring cartridge, and the other end is fixed on the connecting plate. The rotating shaft is provided with an oil filling hole. The utility model has the advantages of 1) simple structure, low manufacture, using and maintenance cost and convenient for wide promotion; 2) reasonable design and long service life.
Description
Technical field
The utility model belongs to the technical field of mechanical transmission annex, specifically is a kind of band transmission Idle wheel.
Background technique
Belt transmission is the mechanical industry kind of drive commonly used, and the belt of various materials is not an elastomer completely, under the effect of pretightening force, after running after a while, will relax because of plastic deformation, makes the initial tension reduction.In order to guarantee ability, need make regular check on the numerical value of initial tension with transmission.As find deficiency, tensioning again could proper functioning.When the centre distance between the belt wheel can not be regulated, generally adopt tensioner apparatus.Tensioner apparatus commonly used is that fork one end is installed contact wheel, perhaps on a Height Adjustable strut contact wheel is installed.The Idle wheel of these structures is installed difficulty, need to use special-purpose handling instrument, and the kinetic friction of each member is big, causes reduce working life.
Summary of the invention
The utility model is in order to solve Idle wheel installation difficulty in the prior art, need to use special-purpose handling instrument, and the kinetic friction of each member is big, causes the problem of reduction in working life, and a kind of band transmission Idle wheel novel, simple in structure, easy for installation is provided.
The utility model adopts following technological scheme: band transmission Idle wheel comprises through the contact wheel of bearing fixing in rotating shaft.Rotating shaft is installed on the connecting plate lower end, and the connecting plate upper end is circular, and axle sleeve is established in its center portion, setting shaft in the axle sleeve, and the peripheral hardware torque spring, an end of dead axle and torque spring is fixed in spring strut, and the other end is fixed in connecting plate.Oil hole is offered at the rotating shaft center.
The beneficial effects of the utility model: 1, simple in structure, manufacturing, use, maintenance cost are low, are convenient to extensive popularization; 2, reasonable in design, long service life.
