Abstract
The utility model relates to an automatic tensioning wheel for an engine belt. The automatic tensioning wheel comprises a fixed shaft, an outer sleeve arranged on the outside of the fixed shaft and a torsional spring arranged in the outer sleeve, wherein one end of the torsional spring is connected with a balance fixed seat, the other end of the torsional spring is connected with a tensioning arm, a belt wheel is arranged on the tensioning arm through a wheel fixing shaft, one end of the wheel fixing shaft close to the tensioning arm is fastened with a bolt which is an outer hexagon bolt, and an oil passage hole is formed in the center of the bolt. An oil inlet passage communicated with the oil passage hole is formed in the center of the wheel fixing shaft, a conical wear-resistant cover is arranged between the fixed shaft and the outer sleeve, and a protruding oil nipple is arranged at the top of the center of the outer hexagon bolt fixed through internal threads. The belt wheel is connected with the wheel fixing shaft through at least two groups of bearings, and bearing spacing gaskets are arranged among the bearings. A dustproof cover is arranged at one end of each of the bearings, and an oil blocking ring is arranged at the other end of each of the bearings.
Description
Technical field
The utility model belongs to machinery field, is specifically related to a kind of belt automatic tensioning belt wheel of motor.
Background technique
Tension pulley is very important parts in belt drive system, can be lax after using because belt is long-term, Idle wheel is to be responsible for giving belt stable tension force, no matter is new belt or old belt, if there is no Idle wheel, lax belt can skid and lose gearing.In contemporary motor car engine, be not only widely used band transmission and driven the annexes such as generator, air condition compressor, fan, needs and bent axle keep the camshaft of strict phase relationship also to adopt belt wheel transmission.Bel-drivenn accessory system is arranged on the front surface of motor conventionally, and wherein each annex is arranged on the belt pulley on axle, for receiving the bel-drivenn power from certain form.Idle wheel is mainly comprised of stationary housing, tension arms, wheel body, torsion spring, rolling bearing and spring axle sleeve etc., and tightness that can be different according to belt, adjusts tension force automatically, makes transmission system stability and safety reliable.But during general belt tension wheel construction handling belt switching Idle wheel, need the outer cubic spanner switching of particular constraints, and charging-up lubricant oil is inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic tensioner for automobile belt, do not need the outer cubic spanner switching of particular constraints, and charging-up lubricant oil is convenient during this structure handling belt switching Idle wheel.
Automatic tensioner for automobile belt of the present utility model, comprises stationary axle, is arranged on the overcoat of stationary axle outside, is arranged on the torque spring in overcoat, and described torque spring one end connects balance fixed base, and the other end connects tension arms; Belt pulley is arranged on tension arms by fixing wheel shaft; Described fixedly wheel shaft is near the same bolton in one end of tension arms, and described bolt center is provided with oil channel hole.
As optimization, described bolt is the fixing outer-hexagonal bolt of internal thread.Described fixedly wheel shaft center can be provided with the oil input channel that same oil channel hole is communicated with.Between described stationary axle and overcoat, can be provided with taper wear sleeve.The outer-hexagonal bolt center top extrusion position fixing at described internal thread can be provided with pump nozzle.
Described belt pulley is connected by least two group bearings with fixing wheel shaft, is provided with bearing separation pad between described bearing.One end at described bearing is provided with dust cover, and the other end of described bearing is provided with oil deflector.Described oil input channel one end is communicated with oil channel hole, and the described oil input channel the other end leads to bearing separation pad position.
On described tension arms, be provided with and lead to the fixedly back oil road in gap between wheel shaft and tension arms.
The fixedly wheel shaft of belt automatic tensioner of the present utility model is fastening with the outer-hexagonal bolt shape of protruding, during handling belt switching Idle wheel, do not need the outer cubic spanner switching of particular constraints, can use opening that motor carries at random, plum blossom, the spanner such as active, time saving and energy saving.Inside and outside silk is outer-hexagonal bolt fixedly, be designed to hollow, as oil channel hole, top, center can fill straight pump nozzle or curved pump nozzle, the fixedly wheel shaft of belt pulley has oil input channel, makes its bearing inside can inject lubricant grease, and bearing and assembly can be increased the service life.
