What sun gear, a gear ring, a planet carrier and several planetary gears formed, a referred to as planet row.Sun gear, gear ring and row
Carrier has a common fixed axis, and planetary gear supporting and fixing is in the planetary gear shaft of planet carrier, and simultaneously and sun gear
It is engaged with gear ring.Between planetary gear and planetary gear shaft is gather formula needle bearing or the needle roller axis with retainer
It holds, the positioning between planet axis and planet carrier is interference fitted using steel ball or using the hole of planet axis and planet carrier.
The installation of densely covered formula needle bearing is more troublesome, and existing a vehicle, a hub reduction are used on the market at present
164 needle rollers need that the needle roller of very little one by one is sticked in planetary gear inner hole with lubricating grease, then wear planet axis
Enter, and be also very careful falling off for needle roller when assembly, the needle bearing carrying with retainer is limited, what is used
In the process it is possible that retainer fragmentation.Positioning for planet axis and planet carrier is easily slid out with steel ball positioning planet axis,
Assembly is inconvenient, is positioned with interference fit, and dismounting is difficult, needs dedicated equipment, and influence secondary use after dismantling.
Utility model content
In order to make up deficiency existing for above structure, the utility model provides a kind of fork truck planet carrier assembly.
The utility model is achieved through the following technical solutions:
A kind of fork truck planet carrier assembly, comprising: the bearing 3 of planetary gear 2, four of planet carrier 1, four and four planet axis
4, the bearing 3 is steel-backed bearing；There are axial hole 41, first through hole 42 and the second through-hole 43, the axial direction in the planet axis 4
Hole 41 is located at 4 side of planet axis, and the first through hole 42 passes through axial hole 41 and vertical with axial hole 41；Second through-hole 43
It is vertical with axial hole 41 and first through hole 42 respectively；Flexible straight pin 5 is assigned in the first through hole 42；The planet axis 4
The other side be machined with the second rectangular channel 44；There are equally distributed four planet axis holes 11, the row on 1 end face of planet carrier
11 outer circle of star axis hole is equipped with the first rectangular channel 110, and 1 middle shaft part of planet carrier is equipped with spline 13.
The axial hole 41 is connected with the first through hole 42 and the second through-hole 43 simultaneously, and the axial hole 41 and first is logical
The diameter in hole 42 is identical.
The outer circle of the bearing 3 and the inner hole of planetary gear 2 are elastic conjunctions, and inner hole and the planet axis 4 of the bearing 3 are
Clearance fit, the planet axis 4 and planet carrier 1 are clearance fits.
First rectangular channel 110 described in when assembly is corresponding with second rectangular channel 44.
Uniformly distributed 4 radial through-hole 12 on 1 side wall of planet carrier, dismantle elastic cylindrical pin 5 by the radial through-hole 12.
The beneficial effect of the utility model compared with the existing technology is:
1, steel-backed bearing is used between planet axis and planet carrier, carrying is high, long service life, and assembly is again convenient, and
And steel-backed bearing is relatively high relative to densely covered formula needle bearing assembly efficiency.
2, the positioning between planet axis and planet carrier uses elastic cylindrical pin, does not need special press-loading device, assembly and disassembly side
Just.
3, three holes in planet axis are run through, and have not only realized the lubrication of planetary gear steel-backed bearing, but also realize elastic cylinder
The location requirement of pin.
