Description

The bearing tuning bearing that a kind of oil cylinder connects
Technical field
The utility model relates to a kind of bearing tuning bearing, the bearing tuning bearing that especially a kind of oil cylinder connects.
Background technique
Oil cylinder mechanical field application widely, mostly the on-link mode (OLM) of current oil cylinder and motion is the cylinder head with earrings joint shaft bearing to be arranged on axis pin base, fixed by bearing pin, oil cylinder acquisition rotates the ability of 180 ° around bearing pin, due to the interference between cylinder head and axis pin base, in the direction of vertical bearing pin, the angle changing rate that earrings joint shaft bearing can rotate is little, limit the sphere of activities of oil cylinder, and the bearing capacity of earrings joint shaft bearing is lower, when bearing heavy duty, flexibility declines.
Model utility content
The purpose of this utility model is to provide a kind of both direction of having mercy on and rotates 180 °, the bearing tuning bearing that the oil cylinder that bearing capacity is high connects, to overcome currently available technology above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
The bearing tuning bearing that a kind of oil cylinder connects, comprise " ten " font bearing pin, double-row roller bearing, bearing cap, two cylinder head coupling shaft bearings and two basic coupling shaft bearings, wherein, two cylinder head coupling shaft bearings and two basic coupling shaft bearings are connected respectively by the transverse axis of double-row roller bearing and described " ten " font bearing pin and the longitudinal axis, described double-row roller bearing and be provided with adjusting play between basic coupling shaft bearing and cylinder head coupling shaft bearing, and carry out pretension by adjustment pad.
By adopting " ten " font bearing pin as bearing pin, making oil cylinder can to obtain in space with two axles of " ten " font bearing pin as rotating center, rotating the ability of 180 °; And because " ten " font bearing pin is by pair of bearings as support, make each bearing need the power of carrying to diminish, this just improves the bearing capacity of bearing relatively; What adopt due to described bearing again is double-row roller bearing, and what bearing was subject to is rolling resistance, and rotational resistance is little, and wasted power diminishes, and improves the efficiency of the bearing tuning bearing that cylinder connects.
Further, described " ten " font bearing pin inside is provided with grease inlet and lubrication channel, and lubrication channel leads to each bearing respectively; Described basic coupling shaft bearing and described cylinder head coupling shaft bearing are respectively arranged with seal groove, in seal groove, are provided with seal ring; Basis coupling shaft bearing and cylinder head coupling shaft bearing are provided with bearing cap.By this structure, lubricating grease is injected from grease inlet, lubricating grease is delivered to each bearing by lubrication channel by lubricating grease, make bearing and " ten " font bearing pin can obtain good lubrication, and seal ring and bearing cap can prevent leaking of lubricating grease, oil film can be formed in airtight environment again, can also external contamination be prevented.
The utility model beneficial effect: the bearing tuning bearing connected by the oil cylinder being arranged to this structure, oil cylinder can to obtain in space with two axles of " ten " font bearing pin as rotating center, rotate the ability of 180 °, and the bearing capacity of oil cylinder and bearing have also been obtained raising.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural drawing of the bearing tuning bearing that the oil cylinder described in the utility model embodiment connects;
Fig. 2 is the sectional view of the bearing tuning bearing A-A position that the oil cylinder described in the utility model embodiment connects.
In figure:
1, bearing cap; 2, bearing; 3, basic coupling shaft bearing; 4, " ten " font bearing pin; 41, grease inlet; 42, lubrication channel 5, cylinder head coupling shaft bearing; 6, seal ring; 7, pad is adjusted.
Embodiment
As depicted in figs. 1 and 2, two cylinder head coupling shaft bearings 5, double-row roller bearing, " ten " font bearing pin 4 and two basic coupling shaft bearings 3 are comprised described in the utility model embodiment, wherein, two cylinder head coupling shaft bearings 5 and two basic coupling shaft bearings 3 are connected respectively by the transverse axis of double-row roller bearing and " ten " font bearing pin 4 and the longitudinal axis, described double-row roller bearing and be provided with adjusting play between basic coupling shaft bearing 3 and cylinder head coupling shaft bearing 5, and carry out pretension by adjustment pad 7.Described " ten " font bearing pin 4 inside is provided with grease inlet 41 and lubrication channel 42, described lubrication channel 42 leads to each bearing 2 respectively, basis coupling shaft bearing 3 and cylinder head coupling shaft bearing 5 are respectively arranged with seal groove, seal ring 6 is provided with in seal groove, bearing cap 1 is connected with each bearing support respectively.
During concrete use, double-row roller bearing is installed in bearing support, install seal ring 6, cylinder head coupling shaft bearing 5 and basic coupling shaft bearing 3 are connected respectively by the transverse axis of bearing 2 and " ten " font bearing pin 4 and the longitudinal axis, hammer into adjustment pad 7 and carry out bearing 2 pretension, then bearing cap 1 is covered, it is firm first basic coupling shaft bearing 3 and basis (or ground) to be installed by mounting screw again, finally be installed to by oil cylinder on the attachment face of cylinder head coupling shaft bearing 5, the other end of oil cylinder connects load; Bearing cap 1, basic coupling shaft bearing 3 and cylinder head coupling shaft bearing 5, " ten " font bearing pin 4, seal ring 6 form enclosed space, double-row roller bearing is surrounded wherein, inject lubricating grease from grease inlet 41, lubricating grease is delivered to each double-row roller bearing by lubrication channel 42 by lubricating grease.
In sum, by the bearing tuning bearing that the oil cylinder of this structure connects, oil cylinder can rotate around two of central axis group bearing 2, obtain in theory with " ten " font bearing pin 4 center as round dot, length of oil cylinder is the interior rotation arbitrarily of the hemisphere of radius, and the bearing capacity of double-row roller bearing is more much larger than earrings joint shaft bearing, so this Noval bearing seat is in heavy duty, and flexibility is significantly improved.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technological scheme, all drops within protection domain of the present utility model.
