Abstract
The utility model discloses a supporting device used on a gear hobbing machine. The supporting device comprises a workbench (1), a bearing (4) and a bearing seat (2) supporting the bearing (4). The workbench (1) is fixedly connected with the bearing seat (2) through a fastener (5). The outer circular face of the bearing seat (2) is matched with an inner hole face of the workbench (1) at certain conical degree. According to the supporting device used on the gear hobbing machine, the combination face of the workbench and the supporting seat is of certain conical degree, the workbench and the bearing seat are good in combining effect and convenient to install, and the precision and the stability of the installation of the workbench and the bearing seat are further improved.
Description
Technical field
The utility model relates to the mach field of gear hobbing, relates in particular to a kind of bracing or strutting arrangement being used on gear-hobbing machine.
Background technology
In existing, be used in the bracing or strutting arrangement on gear-hobbing machine, the bearing block that comprises workbench, bearing and spring bearing, conventionally coordinating between workbench and bearing block is directly that end contact coordinates, workbench periphery and inner hole of bearing seat face stay gap, make the installation accuracy of bearing unstable, or workbench periphery and the interference of inner hole of bearing seat face, contact too closely, make greatly to reduce in service life of bearing and be difficult for installing and removing; Thereby affect machining accuracy and the service life of equipment.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of bracing or strutting arrangement being used on gear-hobbing machine, and the faying face of workbench and bearing block is provided with certain tapering, and both also further improve in conjunction with effective the stability that workbench and bearing block are installed.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of bracing or strutting arrangement being used on gear-hobbing machine, the bearing block that comprises workbench, bearing and spring bearing, described workbench is fixedly connected with by securing member with bearing block, and the periphery of described bearing block and the inner hole surface of described workbench are with the taper fit of 1:40-1:60.
Preferably, the periphery of described bearing block and the inner hole surface of described workbench are with the taper fit of 1:50.
The periphery of described bearing block and the inner hole surface of described workbench are with certain taper fit, installation and removal are convenient, and both are in conjunction with effective, also further improve precision and stability that workbench and bearing block are installed, thereby improved gear-hobbing machine machining accuracy and service life.
Here preferably tapering is 1:50, while being greater than 1:50, in conjunction with poor effect; While being less than 1:50, make workbench and the bearing block periphery processing difficulties to the inner hole surface of the workbench that should locate and bearing block, easily cause bearing block upper end wall excessively thin, yielding, the wall position of corresponding workbench is the position of mounting fastener, easily cause installation site inadequate, therefore preferred tapering is 1:50 here.
Further, when described workbench and bearing block are installed, the workbench faying face of the relatively described workbench of bearing block faying face of described bearing block is provided with the gap of 0.2-0.3mm.
Preferably, described gap is 0.25mm.
During assembling, workbench and bearing block are installed, the periphery of described bearing block just coordinates with certain tapering with the inner hole surface of described workbench, therefore the workbench faying face at the relatively described workbench of bearing block faying face of described bearing block is provided with certain gap, for after fastening good securing member, guarantee that both overlap by faying face completely; Preferably described gap is 0.25mm, also makes the end-play of bearing reach the standard of bearing itself.
Accompanying drawing explanation
Fig. 1 is the structural representation before a kind of bracing or strutting arrangement embodiment being used on gear-hobbing machine of the utility model installs;
Fig. 2 is the structural representation after a kind of bracing or strutting arrangement embodiment assembling being used on gear-hobbing machine of the utility model.
The specific embodiment
As shown in Figure 1, as embodiment of the present utility model, a kind of bracing or strutting arrangement being used on gear-hobbing machine, the bearing block 2 that comprises workbench 1, bearing 4 and spring bearing 4, described workbench 1 is fixedly connected with by securing member 5 with bearing block 2, the inner hole surface of the periphery of described bearing block 2 and described workbench 1 is with the taper fit of 1:40-1:60, and preferred tapering is 1:50 in the present embodiment.
When described workbench 1 is installed with bearing block 2, the workbench faying face 7 of the relatively described workbench 1 of bearing block faying face 8 of described bearing block 2 is provided with the gap 6 of 0.2-0.3mm, and preferred gap 6 is 0.25mm in the present embodiment.
The inner hole surface of the periphery of described bearing block 2 and described workbench 1 is with certain taper fit, installation and removal are convenient, and both are in conjunction with effective, also further improve precision and stability that workbench 1 and bearing block 2 are installed, thereby improved gear-hobbing machine machining accuracy and service life.
Here preferably tapering is 1:50, while being greater than 1:50, in conjunction with poor effect; While being less than 1:50, make workbench 1 and the inner hole surface of the 2 pairs of workbench that should locate 1 of bearing block and the periphery processing difficulties of bearing block 2, easily cause bearing block 2 upper end wall excessively thin, yielding, the wall position of corresponding workbench 1 is the position of mounting fastener, easily cause installation site inadequate, therefore preferred tapering is 1:50 here.
Further, when described workbench 1 is installed with bearing block 2, the workbench faying face 8 of the relatively described workbench 1 of bearing block faying face 8 of described bearing block 2 is provided with the gap of 0.25mm.
During installation, when workbench 1 is installed with bearing block 2, pull bar 3 is fixed on to machining gears on gear-hobbing machine, the circle end face of described bearing block 2 just coordinates with certain tapering with the interior hole end surface of described workbench, therefore described bearing block 2 the workbench faying face 7 of the relatively described workbench 1 of bearing block faying face 8 be provided with certain gap, for after fastening good securing member 5, guarantee that both overlap by faying face completely; Preferably described gap is 0.25mm, also makes the end-play of bearing reach the standard of bearing itself.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
