Description
Technical Field
The utility model belongs to the technical field of machine tools, and particularly relates to a transmission device of a large workbench.
Background
The vertical lathe is different from the common lathe in that the main shaft is vertical, which is equivalent to erecting the common lathe. Because the workbench is in the horizontal position, the machine is suitable for machining heavy parts with large diameters and short lengths.
The vertical lathe can process an inner cylinder, an outer cylinder, a conical surface, an end plane, a groove, a chamfer angle and the like, and the operations of clamping and correcting a workpiece are relatively convenient.
When the table top of the vertical lathe workbench reaches more than 10 meters, the original transmission gear ring has a reference circle diameter of more than 8 meters, the processing difficulty of the gear ring is increased, and the processing quality is difficult to ensure, so that a transmission device suitable for a large workbench is needed.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model provides the transmission device of the large workbench, which has the advantages of ensuring the processing quality and high transmission precision and can effectively meet the transmission requirement of the workbench.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a transmission of large-scale workstation, includes drive end, speed reducer, gear, bearing, axle, drive sleeve, cross roller bearing, the drive end is connected to the speed reducer, and the output of this speed reducer is equipped with the speed reducer gear, the axle wears to establish in the drive sleeve through the inner bearing, is equipped with input gear and output gear on this drive sleeve, input gear and speed reducer gear meshing, cross roller bearing includes cross roller bearing outer lane and cross roller bearing inner circle, cross roller bearing outer lane is equipped with outer ring gear, output gear and outer ring gear meshing, and aforesaid cross roller bearing outer lane is connected with the workstation, and this cross roller bearing inner circle is fixed.
In the above technical scheme, the output end of the speed reducer is provided with a speed reducer bearing for stabilization.
In the technical scheme, the transmission sleeve bearing used for stabilizing is arranged outside the transmission sleeve.
In the technical scheme, the outer ring of the crossed roller bearing is connected with the workbench through bolts.
In the above technical scheme, the driving end is a motor.
The beneficial effects of the utility model are as follows: the device has compact structure, small processing difficulty, guaranteed quality and high transmission precision, and can effectively meet the transmission requirement of a workbench.
Drawings
Fig. 1 is a schematic cross-sectional structure of the present utility model.
Wherein: 1. the device comprises a motor, a speed reducer gear, a transmission sleeve, a shaft, a crossed roller bearing outer ring, a crossed roller bearing inner ring, a workbench, an input gear, an output gear, a speed reducer bearing, a transmission sleeve, a shaft and a transmission sleeve bearing.
Detailed Description
The utility model will be further described with reference to the accompanying drawings and specific examples.
The transmission device of the large-sized workbench shown in fig. 1 comprises a driving end, a speed reducer 2, gears, bearings, a shaft 5, a transmission sleeve 4 and a crossed roller bearing, wherein the driving end is connected to the speed reducer 2, the output end of the speed reducer 2 is provided with the speed reducer gear 3, the shaft 5 is arranged in the transmission sleeve 4 in a penetrating mode through an inner bearing 12, the transmission sleeve 4 is provided with an input gear 9 and an output gear 10, the input gear 9 is meshed with the speed reducer gear 3, the crossed roller bearing comprises a crossed roller bearing outer ring 6 and a crossed roller bearing inner ring 7, the crossed roller bearing outer ring 6 is provided with an outer gear ring, the output gear 10 is meshed with the outer gear ring, the crossed roller bearing outer ring 6 is connected with the workbench 8, and the crossed roller bearing inner ring 7 is fixed.
In the above technical solution, the output end of the speed reducer 2 is provided with a speed reducer bearing 11 for stabilization. Because the workbench is large in mass, one end of the output end of the speed reducer is prevented from being easily damaged due to stress, and the speed reducer bearing 11 is arranged, so that the stress condition of the output end of the speed reducer is better.
In the above technical solution, the transmission sleeve bearing 13 for stabilization is arranged outside the transmission sleeve 4. The workbench has large mass, and the stress on one stress side is too large when the outer ring 6 of the crossed roller bearing is driven to rotate by the transmission sleeve 4, so that the stress condition of the transmission sleeve 4 is balanced better by the transmission sleeve bearing 13.
In the above technical solution, the outer ring 6 of the crossed roller bearing is connected with the workbench 8 through bolts.
In the above technical solution, the driving end is the motor 1.
The motor 1 transmits power to the speed reducer 2, the transmission sleeve 4 rotates through the speed reducer gear 3 and the input gear 9, the transmission sleeve drives the output gear 10 to rotate, and the workbench rotates through the crossed roller bearing outer ring 6.
The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
