Description
Technical field
The utility model relates to main shaft unloading device technical field, specifically a kind of heavy type numerical control lathe spindle off-load
Device.
Background technique
In the various large and medium-sized disks such as space flight, ship, wind-powered electricity generation, water power, military project, mine, train, automobile, axle sleeve, class part
In process, other than having turning accuracy requirement to disk, axis, the outer circle of cover parts, inner hole, these disks, axis, cover parts
Generally require higher metal removal rate and without chatter mark processing request.In this way, it is necessary to the heavy type of a kind of big cutting force and efficiently
Numerically-controlled machine tool.And big cutting force lathe then needs to select high-power, large torque spindle motor, or installs reduction gearbox again
Increase torque；It is transferred on main shaft finally by belt and realizes to the biggish metal removal rate of part and wanted without chatter mark processing
It asks.This lathe requires spindle box and main shaft to have biggish rigidity, and main shaft bearing will have biggish bearing capacity.
Common heavy numerical control horizontal type lathe generallys use spindle pulley and is directly mounted on main shaft, and this mode is usually right
Machine tool mainshaft bearing even main shaft brings very big additional radial pressure, and long-time service can cause to damage to main shaft bearing even main shaft
Wound is to substantially reduce the main shaft bearing even service life of main shaft.And the most crucial component of a machine tool is exactly main shaft portion,
And main shaft bearing and main shaft are the most crucial auxiliary equipments of main shaft portion, the expensive and Production of bearing period is longer, reduces main shaft
Service life with main shaft bearing is an important loss to entire machine tool.If replacing bearing in client's workshop, if
There is no suitable tools, maintenance cost and maintenance cycle also can be very long, and important economic loss is caused to client.
Utility model content
The purpose of this utility model is to provide a kind of heavy type numerical control lathe spindle relief arrangements, eliminate belt for solving
The technical issues of wheel generates extra duty to main shaft.
The technical solution adopted by the utility model to solve its technical problems is that:
A kind of heavy type numerical control lathe spindle relief arrangement, including spindle box, support sleeve, belt pulley, torque connect disk, main shaft with
And off-load component；
Support sleeve links together with spindle box, and main shaft is spindle rotationally arranged in support sleeve and spindle box；Belt pulley is logical
Off-load component matching is crossed to be mounted on the outside of the support sleeve；Torque connects one end that disk is connected to belt pulley, and main shaft connects positioned at torque
In disk, torque connects and links together on the inside of disk with main shaft.
Further, the off-load component includes deep groove ball bearing, and deep groove ball bearing is mounted on the belt pulley and support
Between set.
Further, bearing outer separator is installed between the deep groove ball bearing and belt pulley.
Further, bearing inner spacing collar is installed between the deep groove ball bearing and support sleeve.
Further, the outer end of the deep groove ball bearing is equipped with the shaft block ring that axial restraint is passed in and out to it.
Further, the torque connects and is linked together between disk and main shaft by driving key.
The effect provided in utility model content is only the effect of embodiment, rather than whole effects that utility model is all
Fruit, a technical solution in above-mentioned technical proposal have the following advantages that or the utility model has the advantages that
The power that belt is relayed to belt pulley is acted on by bearing inner support set, bearing outer separator and two pieces deep groove ball bearing
On support sleeve, two pieces deep groove ball bearing can bear biggish radial support power, and such belt is transmitted to the power on belt pulley will
Mitigate significantly, the power for acting on support sleeve will very little.And support sleeve is fixed on spindle box, and is had between support sleeve and main shaft
Gap does not contact, and masterpiece takes less than on main shaft, has the function that main shaft off-load.
Detailed description of the invention
Fig. 1 is the structural profile illustration of the utility model embodiment；
In figure: 1, spindle box 1；2, support sleeve；3, deep groove ball bearing；4, bearing inner spacing collar；5, bearing outer separator；6, axis is used
Retaining ring；7, belt pulley；8, torque connects disk；9, driving key；10, main shaft 10.
Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Utility model is described in detail.It should be noted that illustrated component is not drawn necessarily to scale in the accompanying drawings.The utility model
It is omitted to known assemblies and technical description to avoid being unnecessarily limiting the utility model.
As shown in Figure 1, a kind of heavy type numerical control lathe spindle relief arrangement, including spindle box 11, support sleeve 2, belt pulley 7,
Torque connects disk 8, main shaft 10 and off-load component.The support sleeve 2 is fixed on one by seam allowance positioning, screw with spindle box 11
It rises, main shaft 10 is spindle rotationally arranged in support sleeve 2 and spindle box 11；The belt pulley 7 is mounted on by off-load component matching
2 outside of support sleeve.Torque connects one end that disk 8 is fixed by screws in belt pulley 7, and the outer end of main shaft 10 is located at torque and connects disk
In 8, torque connects disk 8 and is linked together by driving key 9 with main shaft 10.
The off-load component includes bearing inner support set 2, bearing outer separator 5 and two pieces deep groove ball bearing 3, deep groove ball bearing
3 are mounted between the belt pulley 7 and support sleeve 2；The bearing is installed between the outside and belt pulley 7 of deep groove ball bearing 3
Outer separator 5 installs the bearing inner spacing collar 4 between the inside and support sleeve 2 of deep groove ball bearing 3；The outer end of deep groove ball bearing 3
Equipped with the shaft block ring 6 for passing in and out axial restraint to it.
The off-load principle of the present apparatus are as follows: the power that belt is relayed to belt pulley 7 passes through bearing inner spacing collar 4,5 and of bearing outer separator
Two pieces deep groove ball bearing 3 acts on support sleeve 2；Since two pieces deep groove ball bearing 3 can bear biggish radial support power, in this way
The power that belt is transmitted on belt pulley 7 will mitigate significantly, and the power for acting on support sleeve 2 will very little.And support sleeve 2 is fixed on
On spindle box 11, and there is gap not contact between support sleeve 2 and main shaft 10, power just takes less than on main shaft 10, reaches to main shaft
The effect of 10 off-loads.
When torque transmits, the torque that belt pulley 7 is transmitted through acts on torque and connects disk 8, and torque connects disk 8 again by driving key 9
It transfers torque on main shaft 10, to provide the power source of machine cut for main shaft 10.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, on the basis of technical solutions of the utility model, those skilled in the art do not need to pay creativeness
The various modifications or changes that can make of labour it is still within the protection scope of the present utility model.
