Abstract
A machine tool transmission, in particular a spindle transmission, with which the force and/or the torque transfer from an output shaft ( 3 ) of a transmission ( 1 ) takes place directly on a spindle ( 15 ). The spindle ( 15 ) is placed co-axially over the output shaft ( 3 ). An integration of a sealed rotary feed-through is proposed to serve as a transfer device for the flow of cooling fluids, oil or air between the transmission output shaft and the spindle ( 15 ).
Description
The present invention relates to a kind of machine tool gear mechanism, particularly a kind of mainshaft gear case.
In particular, the present invention relates to a kind of mainshaft gear case, wherein, power or moment are directly delivered on the main shaft from the driven shaft of gear-box, wherein, and main shaft and the coaxial setting of driven shaft.In this gear-box, driven shaft directly is connected with main shaft; Can moulding between main shaft and the driven shaft or strength carry out antitorque connection with engaging.In this case, the necessity that has cooling fluid between gear-box driven shaft and the main shaft, oil or transfer of air device.
The objective of the invention is to, a kind of machine tool gear mechanism is provided, particularly start the mainshaft gear case of described type, wherein, have the device that is used between gear-box driven shaft and main shaft, transmitting cooling fluid, oil or air.
This purpose is achieved by machine tool gear mechanism according to the present invention.Wherein, in machine tool gear mechanism according to the present invention, power or moment are directly delivered on the main shaft from the driven shaft of gear-box, wherein, main shaft and the coaxial setting of driven shaft, wherein, integrated swivel coupling in gear-box, this swivel coupling is as the cooling fluid between gear-box driven shaft and the main shaft, the transfer device of oil or air, it is characterized in that, swivel coupling is bearing in the driven shaft of gear-box and comprises the seal disc of motor side and the seal disc of main shaft side, and the seal disc of motor side is connected with power transmission shaft with attaching parts by the pipe of gear-box, and the seal disc of main shaft side is set directly in the main shaft or in the connector that adds.
This gear-box generally includes two-stage planetary gear and corresponding connecting arrangement, thereby has speed discrepancy on the gearratio between gear-box or motor shaft and the driven shaft.The dynamic seal (packing) position that has the pressure that is used to accept volume flow and therefrom produces for this reason according to the present invention.
The present invention a kind of preferred embodiment in, swivel coupling is bearing on the driven shaft and comprises two seal discs, uses as sealing position and the device of accepting differential.Seal disc can comprise different materials and/or have different geometries under the situation of pressure that depends on medium, appearance and volume flow.
Have the further formation of advantage according to the present invention, swivel coupling comprises the spring of compression seal dish, thereby can or seldom not occur leaking when the pressure of medium rises.For the wearing and tearing with seal disc drop to bottom line, two seal discs can for example another spring be separately there being under the situation of media flow use device.
By according to solution of the present invention sealing being displaced to the outside of gear-box, thereby the advantage that produces is to allow to leak and can directly turn back in the fuel tank.In according to prior art solutions, the sealing position must 100% sealing because otherwise gear case oil is subjected to for example pollution of cooling fluid can cause gear-box to damage.
By accompanying drawing the present invention is elaborated for example below, this accompanying drawing illustrates the constructed profile according to a kind of preferred implementation of gear-box of the present invention.The epicyclic gearbox professional that picture usually uses on this machine tool gear mechanism of mainshaft gear case particularly for example has known from applicant's EP1169582B1.Mainshaft gear case shown in the accompanying drawing comprises epicyclic gearbox; Also can use from other types gear-box commonly known in the art.
Accompanying drawing illustrates mainshaft gear case 1, it comprise power transmission shaft 2, driven shaft 3 and be arranged on power transmission shaft and driven shaft between two-stage planetary gear on the line of force direction.Epicyclic gearbox has the sun gear 4 that is connected with power transmission shaft 2, be bearing in the ring gear 5 on the ring gear bearing 6 and constitute the planet carrier 7 and the planetary gear 8 of epicyclic gearbox slave unit.
The linkage unit of gear-box comprises section magnetism 9, and it utilizes connection shift fork 10 effects that are removably set on the connecting axle 11.Driven shaft 3 is by means of being arranged on bearings 13,14 supportings in the bearing housing 12 and being connected with main shaft 15.
Integrated according to swivel coupling of the present invention and gear-box 1, this swivel coupling is as the transfer device of cooling fluid, oil or air between gear-box driven shaft 3 and the main shaft 15.
Swivel coupling is bearing in the driven shaft 3 and comprises two seal discs 16,17, and these two seal discs are as the device that seals the position and be used to accept differential.In this case, seal disc 16 and seal disc 17 constitute as the seal disc of motor side and the seal disc of main shaft side respectively.
The seal disc 16 of motor side is connected with motor shaft or power transmission shaft 2 with sleeve 19 by pipe 18, sun gear 4.The seal disc 17 of main shaft side is set directly on the main shaft 15 or additional connector for example on the shaft coupling.
The shell of swivel coupling is preferably additional by means of bearing 20 integral body or split supporting, and this bearing can be used as ball bearing, rolling bearing, sliding bearing or fluid bearing and constitutes.As appreciable from accompanying drawing, swivel coupling comprises check-valves 21, prevents to manage 18 and connection line dry run under pressure-less state.
In the scope of accompanying drawing illustrated embodiment, swivel coupling comprises the spring 22 of compression seal dish 16,17.
On straight-through situation lower seal position, do not have differential, but the seal disc 16,17 of identical rotation must static sealing.
Because allow to leak according to the outside that the present invention is arranged on gear-box by the sealing position, so have the leakage reversed flow pipe 23 that at least one leads to the fuel tank (not shown).
