The utility model is achieved in that a kind of novel mechanical forcing press small belt pulley holder device, comprises mair motor, main shaft, small belt pulley, self-aligning roller bearing, Y-axis pressure cap, Y-axis bearing, gland, locking nut, end cap, spacer, elastic dowel pin shaft coupling, described small belt pulley is arranged on described main shaft by key connecting, described self-aligning roller bearing is installed at described main shaft two ends, described self-aligning roller bearing is supported by described Y-axis bearing respectively, described main shaft left end self-aligning roller bearing is pushed down by described gland and described end cap and is made main shaft axial location, the right-hand member of described main shaft is connected on motor by described elastic dowel pin shaft coupling, manufactures alignment pin with described locking nut, pushes down described bearing, small belt pulley, spacer, realize the axial location of described small belt pulley, about described Y-axis pressure cap is arranged on described small belt pulley top respectively, about described Y-axis bearing is arranged on described small belt pulley bottom, described Y-axis pressure cap is positioned in described Y-axis bearing respectively by alignment pin.
Optimize, this left and right bearing covers has fuel feed hole respectively.
Optimize, this right bearing seat is provided with spill port.
Optimize, the structural design of this spacer is centrifugal seal.
The advantage of utility model is:
1, small belt pulley bearing block is supported, connect electric machine main shaft by shaft coupling, eliminate the radial load of electric machine main shaft, extend electrical machinery life.
2, diaxon bearing lays respectively at small belt pulley two ends, compares one-sided support, stressed evenly, decrease the vibrations of belt, reduce noise.
3, adopt elastic dowel pin shaft coupling, structure is simple, easy to manufacture, and disassembling, assembling and replacing is convenient, counteracts the impact because both sides coaxiality deviation causes, long service life.
4, bearing block lubrication concentrates oil return, and the lubricating oil getting back to cross girder can be recycled, and decreases the leakage of lubricating oil, saves cost.
