Description
[technical field]
The utility model relates to device for revolving and driving field, especially relates to a kind of device for revolving and driving with curved-tooth bevel gear wheel set and slewing bearing combination.
[background technique]
Known, traditional device for revolving and driving is the mechanical transmission combining with slewing bearing and cylindrical gearing pair or cylindrical worm gearing transmission pair, its be generally adopt common cylindrical gears or worm gear as the outer ring of slewing bearing with cylindrical gears or cylindrical worm coordinate accordingly; But, in long-term practical application, find, in the time that device for revolving and driving adopts common cylinder gear transmission, this revolution drives and is only applicable to the driving of parallel axes, and can not realize concurrent aces transmission, secondly, it is poor that column gear transmission also has transmission stability, contact ratio and overlap ratio is less, the weak deficiency that waits of bearing capacity, simultaneously, cylindrical gears is more responsive for alignment error, this is not only easy to form EDGE CONTACT, but also is easy to produce noise and vibration, has influence on the operation of device for revolving and driving; In the time that device for revolving and driving adopts Worm Wheel System, although can realize large velocity ratio, but because worm gear pair transmission efficiency is lower, and frictional heating phenomenon is more serious, meanwhile, it is higher to lubricating requirement, is also easy to wearing and tearing etc., therefore, adopt the uncomfortable cooperation high speed rotary of device for revolving and driving of Worm Wheel System; In sum, the occasion that existing device for revolving and driving is had relatively high expectations at high speed rotary, heavy duty and transmission stability has deficiency in various degree.
[summary of the invention]
In order to overcome the deficiency in background technique, the utility model discloses a kind of spiral bevel gear device for revolving and driving, described device not only can meet at a high speed, the revolution of heavy duty drives requirement, and stable drive, and running noise is less.
For achieving the above object, the utility model adopts following technological scheme:
A kind of spiral bevel gear device for revolving and driving, described device comprises spiral bevel gear, tapered roller bearing, housing, slewing bearing inner ring, revolution support ball and rotary table; In described spiral bevel gear, the wheel shaft of steamboat is installed on hull outside by tapered roller bearing, the middle part of this housing is connected with one end end face of slewing bearing inner ring, and the other end outer wall of slewing bearing inner ring supports ball by revolution and coordinates with the inwall of bull wheel in spiral bevel gear; Described bull wheel engages with steamboat, and bull wheel outer end end face is connected with rotary table; Described rotary table does not contact with housing with slewing bearing inner ring.
Described spiral bevel gear device for revolving and driving, together with described housing is bolted to connection with slewing bearing inner ring.
Described spiral bevel gear device for revolving and driving, together with described bull wheel is bolted to connection with rotary table.
Owing to adopting technological scheme as above, the utlity model has following beneficial effect:
Spiral bevel gear device for revolving and driving compact structure described in the utility model, stable drive, bearing capacity is stronger, and transmission efficiency is higher; Because described device has adopted spiral bevel gear as power transmission member, thereby make the crossed axis angle between the input shaft of revolution driving and the turning axle of revolution driving can realize the design of 10～90 °, and then met the occasion of some unparallel shaft transmission usage requirements, reach to realize and intersected driven off by shaft object; Secondly, due under equal volume, spiral bevel gear not only has the features such as large, the local conjugation contact of contact ratio, and insensitive for alignment error, is difficult for producing EDGE CONTACT, simultaneously, its bearing capacity is also 3～5 times of common cylinder gear, and therefore, described device can be realized at a high speed, the revolution of heavy duty drives requirement, and stable drive, running noise is less.
[brief description of the drawings]
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, steamboat; 2, bull wheel; 3, tapered roller bearing; 4, housing; 5, slewing bearing inner ring; 6, ball is supported in revolution; 7, rotary table.
[embodiment]
Can explain in more detail the present invention by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Spiral bevel gear device for revolving and driving described in 1 by reference to the accompanying drawings, described device comprises spiral bevel gear, tapered roller bearing 3, housing 4, slewing bearing inner ring 5, revolution support ball 6 and rotary table 7; In described spiral bevel gear, the wheel shaft of steamboat 1 is installed on housing 4 outsides by tapered roller bearing 3, thereby is convenient to by steamboat 1 input power; The middle part of described housing 4 is connected with one end end face of slewing bearing inner ring 5, thereby plays the effect that utilizes housing 4 to fix slewing bearing inner ring 5; For ease of dismounting, can housing 4 and slewing bearing inner ring 5 be fixed together by bolt; The other end outer wall of described slewing bearing inner ring 5 supports ball 6 by revolution and coordinates with the inwall of bull wheel in spiral bevel gear 2, adopt the outer ring of bull wheel 2 as slewing bearing in described device, thereby reach compact structure, be more conducive to the object of transmission; Described bull wheel 2 engages with steamboat 1, and bull wheel 2 outer end end face is connected with rotary table 7, thereby when by steamboat 1 input power, can utilize bull wheel 2 to drive rotary table 7 to move; For ease of dismounting, can bull wheel 2 and rotary table 7 be fixed together by bolt; Described rotary table 7 does not contact with housing 4 with slewing bearing inner ring 5.
While implementing spiral bevel gear device for revolving and driving described in the utility model, the application that need drive according to revolution requires to determine the gear ratio of spiral bevel gear, crossed axis angle, according to transmitted power, the number of teeth of curved-tooth bevel gear wheel set is determined in the requirement of working speed, modulus, determine the spiral bevel gear bull wheel that will adopt according to the structural requirement of slewing bearing outer ring, determine the housing of the device for revolving and driving adopting according to the installation requirement of spiral bevel gear, and select suitable lubricating system, the supporting means of sealing means and input shaft etc., then just can be by having carried out corresponding operating to steamboat input power, it should be noted that because described device adopts spiral bevel gear and carry out power transmission, therefore higher to the seal request of device, therefore should adopt the mode of bath lubrication to be lubricated.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
