The belt pulley is sleeved on the bearing block so as to solve the problem of overhanging of the belt pulley, transmission rigidity is high, the belt pulley shaft is connected with the grinding wheel spindle by the gear coupling to guarantee coaxiality, and the grinding wheel transmission is simple and compact in structure and convenient in processing, and improves grinding precision of the centerless grinding machine with a double-support structure.
Description
Technical field
The utility model relates to centerless grinder, specifically a kind of emery wheel transmission device that is used for centerless grinder.
Background technology
When centerless grinder adopted double supporting structure, being connected again after its crucial part is running part and grinding wheel spindle is thrown off needed to guarantee its axiality and off-load rigidity.The running part of existing centerless grinder often adopts belt transmission, Pulley shaft is grinding on the support body by bearing block support, belt pulley overhangs and is installed in an end of Pulley shaft, the other end of Pulley shaft links to each other with grinding wheel spindle by sliding cross coupling, for spline is connected, be connected for key between grinding wheel spindle and the sliding cross coupling between Pulley shaft and the sliding cross coupling.The shortcoming of above-mentioned drive mechanism is: crosshead shoe and spline are because of the limitation of its machining accuracy, can not guarantee the axiality of grinding wheel spindle and Pulley shaft, particularly the wearing and tearing of slide block and spline strengthen with post gap, thereby can produce the crudy that vibration influences the grinding part during transmission, user's repercussion for a long time is very big; In addition, the belt pulley installation that overhangs, transmission rigidity is poor.
Summary of the invention
The utility model provides a kind of emery wheel transmission device at above-mentioned the deficiencies in the prior art, and this installs, and not only axiality is good, and the transmission rigidity height.
The technical scheme that provides according to the utility model, a kind of emery wheel transmission device, comprise grinding wheel spindle, Pulley shaft, belt pulley and be fixed on the bearing block that grinds on the support body, described grinding wheel spindle and the coaxial setting of described Pulley shaft, feature is: described Pulley shaft matched in clearance ground runs through described bearing block, the one end is connected with described grinding wheel spindle by gear coupling, its other end is provided with ring flange, fixedly connected with a side of described belt pulley in the inboard of described ring flange, described belt pulley is sleeved on the described bearing block rotationally.
Be provided with two second bearings between described belt pulley and the described bearing block.
The opposite side of described belt pulley is fixedly connected with gland.
Be provided with clutch shaft bearing between one side of the close described grinding wheel spindle of described bearing block and the described Pulley shaft.
Described gear coupling comprises intermeshing external gear and internal gear, and described external gear is fixed on the end of described Pulley shaft, and described internal gear is fixed on the end of described grinding wheel spindle.
The profile of tooth of described external gear and described internal gear is the arc toothed structure of involute.
Described external gear is connected by woodruff key with described Pulley shaft.
Compared with the prior art the utility model has the following advantages: the utility model is sleeved on belt pulley on the bearing block, has solved the problem that overhangs of belt pulley, the transmission rigidity height; Pulley shaft is connected by gear coupling with grinding wheel spindle, has guaranteed axiality; The utility model is simple in structure, compact, and is easy to process, improved the grinding accuracy of double supporting structure centerless grinder.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the embodiment in the accompanying drawing the utility model is further described.
Among Fig. 1, comprise belt pulley 1, bearing block 2, mill support body 3, external gear 4, Pulley shaft 5, internal gear 6, grinding wheel spindle 7, clutch shaft bearing 8, gland 9, second bearing 10, ring flange 11 etc.
As shown in Figure 1, the utility model is a kind of emery wheel transmission device of double base centerless grinder, comprises grinding wheel spindle 7, Pulley shaft 5, belt pulley 1 and is fixed on the bearing block 2 that grinds on the support body 3, grinding wheel spindle 7 and Pulley shaft 5 coaxial settings.The utility model runs through bearing block 2 with Pulley shaft 5 matched in clearance ground, the one end is connected with grinding wheel spindle 7 by gear coupling, its other end is provided with ring flange 11, fixedlys connected with a side of belt pulley 1 in the inboard of ring flange 11, and belt pulley 1 is sleeved on the bearing block 2 rotationally.
Be provided with pack into the endoporus of belt pulley 1 of two second bearings, 10, the second bearings 10 between belt pulley 1 and the bearing block 2, belt pulley 1 is bearing on the bearing block 2 by these two second bearings 10, has solved the problem that overhangs of belt pulley 1, the transmission rigidity height.The opposite side of belt pulley 1 is fixedly connected with gland 9, plays location second bearing 10 and dustproof.
Can also be provided with clutch shaft bearing 8 between one side of bearing block 2 close grinding wheel spindles 7 and the Pulley shaft 5, clutch shaft bearing 8 has been strengthened the supporting role to Pulley shaft 5.
The said gear shaft coupling comprises intermeshing external gear 4 and internal gear 6, and external gear 4 is fixedly connected on the end of Pulley shaft 5 by woodruff key, and internal gear 6 is fixed on the end of grinding wheel spindle 7.
The profile of tooth of external gear 4 and internal gear 6 is the arc toothed structure of involute, and the circular arc of the flank of tooth can be adjusted the axiality between grinding wheel spindle 7 and the Pulley shaft 5.
When belt drove belt pulley 1 transmission, bearing block 2 played the off-load effect by second bearing 10, and connected with internal gear 6 on being fixed tightly in grinding wheel spindle 7 with external gear 4 on the Pulley shaft 5 that belt pulley 1 tightens up, thus 7 rotations of drive grinding wheel spindle.
The utility model is simple in structure, compact, and is easy to process, improved the grinding accuracy of double supporting structure centerless grinder, and transforms on existing lathe easily.
