Abstract
The utility model discloses a bulking machine pulley transmission structure which comprises a motor pulley, a bulking machine transmission shaft, a bulking machine shell, a large pulley and a belt, wherein the bulking machine transmission shaft is mounted on the bulking machine shell by a bearing, and the motor pulley and the large pulley are connected by the belt. The bulking machine pulley transmission structure is characterized in that the large pulley is rotatably connected with a bearing seat by the bearing, the bearing seat is fixedly mounted on the bulking machine shell, and the large pulley is fixedly connected with a spline coupling sleeve which is fixedly connected with the bulking machine transmission shaft. The bulking machine pulley transmission structure adopting the structure enables the large pulley with large self weight to be fixed on the bearing seat on the bulking machine shell, enables the weight of the large pulley to act on the bearing seat to be transferred to the bulking machine shell but not to directly act on the bulking machine transmission shaft, prevents the transmission shaft from generating flexural moment deformation and prevents parts in a bulking chamber from colliding due to the flexural moment deformation so as to prolong the service life of the bulking machine.
Description
Technical field
The utility model relates to a kind of belt wheel drive mechanism of belt wheel drive mechanism, especially bulking machine.
Background technique
At present, the transmission of bulking machine all is to adopt the belt wheel drive mechanism, comprise electrical machine belt pulley, belt, big belt wheel, bulking machine transmission shaft, bulking machine casing, the bulking machine transmission shaft by Bearing Installation on the bulking machine casing, big belt wheel is directly installed on the bulking machine transmission shaft with key joint, and electrical machine belt pulley drives big belt wheel by belt and rotates.When running up,, make transmission shaft produce bigger moment of flexure distortion easily, the component in the Builking cavity are bumped easily, cause damage parts and cause danger because big belt wheel itself is heavier by this kind connecting structure; And the bending of transmission shaft reduces the coaxality of big belt wheel and transmission shaft, makes transmission shaft be subjected to bigger radial force and axial force simultaneously, causes transmission shaft and main transmission main bearing to damage easily, has reduced working life.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of bulking machine belt wheel drive mechanism that can not make transmission shaft produce the moment of flexure distortion to be provided.
The purpose of this utility model is achieved in that bulking machine belt wheel drive mechanism, comprise electrical machine belt pulley, bulking machine transmission shaft, bulking machine casing, big belt wheel, belt, the bulking machine transmission shaft by Bearing Installation on the bulking machine casing, electrical machine belt pulley connects by belt with big belt wheel, it is characterized in that big belt wheel connects by bearing and bearing support rotation, described bearing support is fixedly mounted on the bulking machine casing, big belt wheel fixed connection spline coupling sleeve, spline coupling sleeve fixed connection is on the bulking machine transmission shaft.
Further, the bearing between described big belt wheel and the bearing support has two, is supported with spacer ring between the two bearings, and second bearing left side on the left side is provided with baffle plate, location pin, and the clutch shaft bearing right side on the right is provided with bearing cap.
Further, be equipped with to be equipped with between oil sealing, bearing cap and the bearing support between oil sealing, bearing support and the bulking machine transmission shaft between described splined cover and the bearing support oil sealing is installed, have oilhole on the bearing support, oilhole is provided with plug cock.
Owing to adopted technique scheme, self heavier big belt wheel is bound up on the bearing support that is fixed on the bulking machine casing, the weight of big belt wheel acts on bearing support and passes to the bulking machine casing, and do not act directly on the bulking machine transmission shaft, avoided transmission shaft generation moment of flexure distortion and, prolonged the working life of bulking machine because moment of flexure is out of shape the collision of the component generation in the Builking cavity that causes.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Among the figure: 1, big belt wheel, 2-1, bearing, 2-2, bearing, 3, baffle plate, 4-1, oil sealing, 4-2, oil sealing, 4-3, oil sealing, 5, pin, 6, accumulator, 7, the splined cover, 8, spacer ring, 9, bearing cap, 10, plug cock, 11, bearing support, 12, the bulking machine transmission shaft, 13, the bulking machine casing, 14, belt, 15, electrical machine belt pulley, 16, motor.
Embodiment
As Fig. 1, among the embodiment shown in Figure 2, motor 16 is by electrical machine belt pulley 15, belt 14 drives big belt wheel 1 and rotates, in the big belt wheel 1 two bearings 2-1 and bearing 2-2 are housed, support and all be installed on the bearing support 11 with spacer ring 8 between bearing 2-1 and the bearing 2-2, bearing support 11 is fixed on the bulking machine casing 13, the bearing 2-2 on the left side is by baffle plate 3, pin 5 location, the bearing 2-1 on the right is sealed by bearing cap 9, spline coupling sleeve 7 is fixed on the big belt wheel 1 by Bolt Connection, and adopt spline to connect, thereby drive 12 runnings of bulking machine transmission shaft with bulking machine transmission shaft 12.Have oilhole on the bearing support 11, in work running engineering, lubricant oil can be joined in the accumulator 6 between big belt wheel 1 and bearing 2-1 and the bearing 2-2 by the plug cock on the bearing support 11 10 by oil pump and to go, and constantly circulation, play lubricating bearings 2-1 and bearing 2-2 and cooling effect, be equipped with to be equipped with between oil sealing 4-3, bearing cap 9 and the bearing support 11 between oil sealing 4-1, bearing support 11 and the bulking machine transmission shaft 12 between splined cover 7 and the bearing support 11 oil sealing 4-2 is installed, to prevent oil leakage.The art of this patent compared with prior art; use bearing support 11 owing to increase; make the bending resistant section coefficient of bulking machine transmission shaft 12 increase tens times; significantly reduced the rate of curving of transmission shaft 12; improved the coaxality of big belt wheel 1 and bulking machine transmission shaft 12, strengthened driving force, avoided colliding the damage parts of bringing and danger because of part and inwall that bending shaft causes being installed on the transmission shaft; protect transmission shaft and bearing, prolonged its working life.Circulating oil path plays lubricating bearings and other parts, reduces friction, and machine is cooled off at the high temperature that working procedure produces, protection part life-saving.
