Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
This utility model provides a kind of suspension arm of lorry-mounted crane slewing equipment, and including base, gyroaxis and driving means 2, gyroaxis is arranged on base.Described base includes substrate 3, lower bearing plate 6 and gland 10, lower bearing plate 6 and gland 10 are all installed on the substrate 3 by bolt 5, described gyroaxis includes column 12 and fluted disc 4, and fluted disc 4 is fixed on the bottom of column 12, and fluted disc 4 is arranged between lower bearing plate 6 and gland 10.One group of cylindrical roller 9, the often spacing and righting by roller centralizing bracket 13 of each cylindrical roller 9 in group it is each provided with between fluted disc 4 and lower bearing plate 6, between fluted disc 4 and gland 10.
In the arm swing process of lorry-mounted crane, gyroaxis should bear gravitational load, again can be by turning torque effect.In this case, the pressure of the interaction between fluted disc 4 with lower bearing plate 6, between fluted disc 4 and gland 10 is the biggest, therefore, it is provided with cylindrical roller 9 in the both sides up and down of fluted disc 4, can farthest reduce frictional resistance, also abrasion be can reduce, and then machinery driving efficiency and the service life of the direct parts rubbed improved.
The side of described gland 10 is provided with square hole, and the output shaft of described driving means 2 is provided with gear 1, and gear 1 engages with fluted disc 4 after square hole, and by this structure, driving means 2 is driven back to rotating shaft and rotates.
Described lower bearing plate 6 and gland 10 all position on the substrate 3 by alignment pin 7, the setting of alignment pin 7 can ensure that each gland of lower bearing plate 6 10 positional stability on the substrate 3 and positioning precision, and then ensure bearing arrangement stable operation, and ensure the precision of bearing.
It is provided with annular boss on described substrate 3, described lower bearing plate 6 is arranged on the inner side of annular boss, the medial surface of annular boss coordinates with the lateral surface of lower bearing plate 6, and described gland 10 is arranged on the outside of annular boss, and the lateral surface of annular boss coordinates with the medial surface of gland 10.The setting of annular boss so that assemble shaft bearing plate 6 and gland 10 at present and can be easier to location, be therefore more convenient for installing.It addition, the setting of annular boss also further increases the rigidity of base plate so that the stability of frame for movement is higher.
On described lower bearing plate 6, gland 10 and fluted disc 4, the position corresponding with cylindrical roller 9 is provided with annular groove, annular liner plate 8 all it is inlaid with in each annular groove, being provided with, on annular liner plate 8, the circular orbit adapted with cylindrical roller 9, cylindrical roller 9 rolls in circular orbit.When bearing wear was lost efficacy, only need to change annular liner plate 8 or cylindrical roller 9, not only make maintenance cost obtain effective reduction, also reduce the wearability requirement to fluted disc 4.Described annular liner plate 8 is made up of bearing steel, make use of the feature that bearing steel wearability is good, it is ensured that the service life of bearing arrangement.
Described roller centralizing bracket 13 is made up of pyrite, and the pyrite softer by quality makes roller centralizing bracket, compared with the steel harder by quality, not only more resistant to mill, and is easier to processing.
Described driving means 2 is hydraulic motor, and hydraulic motor can be driven by the power takeoff on automobile chassis transmission device, and power source easily obtains and is easily controlled.
Described column 12 is welded with reinforcing gusset 11 with the junction of fluted disc 4, further increases the structural strength of gyroaxis.
