Abstract
The utility model relates to an engineering equipment field, concretely relates to slewer, including strutting arrangement, drive arrangement, slewer, the gear wheel, drive arrangement and strutting arrangement are connected, and slewer and strutting arrangement are connected, and the gear wheel is connected with slewer, and big gear package draws together the periphery, and drive arrangement includes pinion and rolling mechanism, pinion and large gear, rolling mechanism along gear wheel periphery motion. Like this, just can avoid pinion and gear wheel separately to cause work unstable because of the meshing, avoid the impact, alleviate weight, improve the atress situation of pinion with large gear, prolong life, reach reduce cost, the purpose of raising the efficiency.
Description
Technical field
This utility model is related to engineering equipment field, and in particular to a kind of slewing equipment.
Background technology
In the crane gear for needing revolution to be operated, driving is needed to be turned round, this is accomplished by slewing equipment.
When lifting tonnage is less, using revolving support, internal drive can just achieve the goal.When lifting weight is big,
Revolving support cannot just meet requirement, it is necessary to the slewing equipment of external drive.Generally, the slewing equipment of external drive is due to little
Gear and gear wheel engage the power for producing little gear can be caused to deviate gear wheel, at this moment adopt spring with ensure gear wheel with it is little
The engagement of gear.But due to causing size larger using the complex structure of spring, heavier-weight is relatively costly；Meanwhile, spring meeting
As tired reason causes job insecurity, inefficiency is caused.
Utility model content
In view of this, it is necessary to which a kind of quickly and easily a kind of slewing equipment is provided.
A kind of slewing equipment, including：
Support meanss；
Driving means；
The driving means are connected with the support meanss；
Gyroaxis；
The gyroaxis is connected with the support meanss；
Gear wheel；
The gear wheel is connected with the gyroaxis；
The driving means are connected with the gear wheel.
The driving means include：
Little gear；
The little gear is engaged with the gear.
Preferably, the driving means also include：
Rolling mechanism.
The gear wheel includes periphery；
The rolling mechanism is moved with the circumference contact and along the periphery.
As a result of above-mentioned technical proposal, the beneficial effects of the utility model are：
Contacted with gear wheel using roller, ensure little gear engage with gear wheel, alleviate weight, improve gear wheel with
The force-bearing situation of little gear, extends service life, has reached raising efficiency, the purpose of reduces cost.

Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is A-A cross-sectional schematics of the present utility model.
Fig. 3 is A-A cross-sectional schematics of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is described further to this utility model.It should be appreciated that specific embodiment described herein is only new to explain this practicality
Type, is not used to limit this utility model.
Embodiment
A kind of slewing equipment, including support meanss as Figure 1-3 1, gyroaxis 2, driving means 3, gear wheel 4, greatly
Gear 4 is fixedly connected with gyroaxis 2, and gyroaxis 2 is rotatably connected with support meanss 1, and driving means 3 are fixed with support meanss 1 and connected
Connect, driving means 3 are connected with gear wheel 4.
Gear wheel 4 includes gear 42 and periphery 41.
Driving means 3 include deceleration device 33, idler wheel mechanism 32.
Deceleration device 33 includes reducing gear 332, little gear 331.
Idler wheel mechanism 32 includes supporting mechanism 322, roller 321.
Support meanss 1 include support base 13, drive bearing 11, connecting shaft 12.
Driving means 3 are fixedly connected with bearing 11 is driven；Bearing 11 is driven to be connected with support base 13 by connecting shaft 12.
Bearing 11 is driven there are two junction points, each junction point is connected with support base 13 by connecting shaft 12.So, drive
Bearing 11 cannot be rotated.
Driving means 3 may also comprise 2 sets of reductors and 2 sets of idler wheel mechanisms 32.
Slewing equipment may also comprise 2 sets or more driving means 3.
The roller 321 of idler wheel mechanism 32 is contacted with the periphery 41 of gear wheel 4 and the periphery 41 along gear wheel 4 is rolled.
When little gear 331 is engaged with gear wheel 4, the power that engagement is produced has inclines little gear 331 detached with gear wheel 4
To roller 321 is rolled along the periphery 41 of gear wheel 4, is controlled the distance between little gear 331 and gear wheel 4, is made little gear
331 cannot separate with gear wheel 4, keep engagement, it is to avoid impact, improve job stability, increase the service life.
Reducing gear 332 is provided with eccentric throw, when mounted, eccentric throw can be adjusted so as to adjust little gear 331 with it is big
The centre-to-centre spacing of gear 4, and then ensure best engagement, job stability is improved, is increased the service life.
As a result of above-mentioned technical proposal, the beneficial effects of the utility model are：
Roller 321 is rolled along the periphery 41 of gear wheel 4, is controlled the distance between little gear 331 and gear wheel 4, is made
Little gear 331 cannot be separated with gear wheel 4, keep engagement, it is to avoid impact, improved job stability, increased the service life.
Reducing gear 332 is provided with eccentric throw, when mounted, eccentric throw can be adjusted so as to adjust little gear 331 with it is big
The centre-to-centre spacing of gear 4, and then ensure best engagement, job stability is improved, is increased the service life, reached raising effect
Rate, the purpose of reduces cost.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all
Any modification, equivalent and improvement for being made etc. within the spirit of the present utility model and principle, should be included in practical
Within new protection domain.
