Abstract
The present invention relates to a band wheel unloading device for impact sand-making machine. It can reduce, even prevent main shaft from producing bending moment by band wheel, so that it can further reduce cost. The described band wheel at least has two coaxial axial inner holes which are different in inner diameter in which one end close to bearing seat is an axial inner hole whose inner diameter is larger, another end is cover-mounted on the main shaft by means of tight fit. The described band wheel unloading device includes unloading sleeve, said unloading sleeve is cover-mounted on main shaft, one end of said unloading sleeve is fixed on the bearing seat, its another end is positioned in the axial inner hole whose inner diameter is larger and is connected with said band wheel by means of bearing.
Description
Technical field
The present invention relates to a kind of impact sand production arbor, relate in particular to a kind of belt wheel relief arrangement that is applied to impact sand production machine.
Background technology
Main shaft connects with generally adopting key or tensioner cover connecting of belt wheel in impact sand production machine or the vertical impact crusher at present, because this machine power of motor is all bigger, so main shaft is except bearing moment of torsion, also to bear because the moment of flexure that radial load produced of band, loss and generation inconsistent phenomenon have so just been quickened to main shaft, generally,, still improved cost so again so when design, usually select thicker main shaft for use in order to reach requirement of strength.
Summary of the invention
Technical problem to be solved by this invention provides a kind of belt wheel relief arrangement that is applied to impact sand production machine, the moment of flexure that it can reduce even avoid belt wheel that main shaft is produced, and then can reduce cost.
In order to solve above technical problem, the invention provides a kind of belt wheel relief arrangement that is applied to impact sand production machine, it is characterized in that, described belt wheel has two concentrics at least but axial bore that internal diameter varies in size, wherein the end near bearing block is the bigger axial bore of internal diameter, the other end is set on the main shaft by tight fit, described belt wheel relief arrangement comprises the off-load cover, off-load cover sky is enclosed within on the main shaft, one end of off-load cover is fixed on the bearing block, and the other end is positioned at the bigger axial bore of described internal diameter and connects with belt wheel by bearing.
Because belt wheel of the present invention is provided with the ladder axial bore and is provided with the off-load cover that sky is enclosed within main shaft, and an end of off-load cover embeds and connects with belt wheel in the bigger axial bore of the internal diameter of belt wheel and by bearing, the other end of off-load cover is fixed on the bearing block, like this when belt wheel rotates, because the off-load cover is nearer from the power source than main shaft, Dai pulling force at first is pressed in off-load and puts so, and an end of off-load cover is fixed on the bearing block, this pulling force has been released on the bearing block by the off-load cover at last so, rather than on the main shaft, the moment of flexure that main shaft bore is lowered even is avoided like this, and then has reduced the loss of main shaft.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a belt wheel relief arrangement structural representation of the present invention.
The specific embodiment
As shown in Figure 1, it is a belt wheel relief arrangement structural representation of the present invention.At first, the difference of belt wheel 10 of the present invention and existing belt wheel is, it has two concentrics at least but axial bore 14,15 that internal diameter varies in size, wherein the end near bearing block 3 is the bigger axial bore of internal diameter 15, the other end is set on the main shaft 9 by key 11 or tensioner cover, also have pressing plate 12 to be pressed in key 11 outsides in addition, pressing plate 12 usefulness bolts 13 are fastened on the belt wheel 10, the off-load of belt wheel relief arrangement is overlapped 4 skies and is enclosed within on the main shaft 9, one end of off-load cover 4 is fixed on the bearing block 3, and the other end is positioned at axial bore 15 and connects with belt wheel 10 by bearing 6.
Its middle (center) bearing 6 is as follows with the draw bail that belt wheel 10 connects, at first bearing 6 is made up of two bearings, and be installed on the off-load cover 4, in two bearings intervals of bearing 6, overcoat 7 and interior cover 8 are housed, overcoat 7 and interior cover 8 all are contained on the belt wheel 10, gland 5 is pushed down the outer ring of bearing 6, and gland 5 is fastened on the belt wheel 10.
The outer ring, gland 5 is fastened on the belt wheel 10.
The similar L type of the shape of unloader sleeve 14 mainly is convenient to connect with bearing block 3 and belt wheel 10.
Claims (3)
