The cylindrical roller bearing and the thrust ball bearing on the existing shaft sleeve simultaneously bear axial thrust effect and radial thrust effect so that the service life is greatly shortened, the bearing even the device is easy to be damaged and the replacement and maintenance cost of spare parts is increased. The feed screw feeding device disclosed by the utility model comprises a ball feed screw, a shaft sleeve and a shaft sleeve seat; a stepped shaft is arranged on one side of the shaft sleeve, and a plain shaft is arranged on the other side of the shaft sleeve; a thrust ball bearing and a cylindrical roller bearing are spliced on the stepped shaft; the shaft sleeve is in splicing fit with the seat hole of the shaft sleeve seat; the ball feed screw is connected with a shaft sleeve key, wherein a conical roller bearing is matched and spliced on the plain shaft, and the conical roller bearing is matched and spliced with the seat hole. The internal structure of the device is optimized, so that the device can bear larger axial thrust and radial thrust to ensure good work; therefore, the service life of the device is prolonged, the maintenance cost of the device and the replacement cost of spare parts are reduced.
Description
Technical field
The utility model relates to a kind of machine tool feed device, refers in particular to a kind of leading screw feed arrangement.
Background technology
Prior motor drives the device of leading screw feeding, is plugged with bearing with cooperation on the axle sleeve that the leading screw key is connected, and above-mentioned bearing is separately positioned on the both sides of axle sleeve, and above-mentioned bearing includes cylinder roller bearing and thrust ball bearing.
The performance of above-mentioned cylinder roller bearing mainly is presented as: it is big to bear the radial load ability, and rigidity is strong, and bearing capacity is big, receive load after distortion little.
The performance of above-mentioned thrust ball bearing mainly is presented as: can bear axial load, but can not bear radial load.
Because of thrust ball bearing can't bear load radially, so existing axle sleeve two ends are cylinder roller bearing, and between above-mentioned two cylinder roller bearings, thrust ball bearing are set.
In the middle of practical work process; Produce nondirectional axial force and radial load by the leading screw that motor drove, make the cylinder roller bearing and the thrust ball bearing that are arranged on the existing axle sleeve bear the effect of axial force and the effect of radial load simultaneously, and because cylinder roller bearing is difficult to bear bigger axial force; Thrust ball bearing is difficult to bear bigger radial load; So greatly reduction of service life, cause the damage of bearing and even device easily, increased the replacing and the maintenance cost of part.
The utility model content
The technical problem that one, will solve
The purpose of the utility model is to existing in prior technology the problems referred to above, the spy provide a kind of can be bigger carrying axial force and radial load and guarantee the leading screw feed arrangement of its works fine.
Two, the technical scheme for solving the problems of the technologies described above
The utility model leading screw feed arrangement includes ball-screw, axle sleeve and sleeve block, and above-mentioned axle sleeve one side is a multidiameter; Opposite side is an optical axis, is plugged with thrust ball bearing and cylinder roller bearing on the above-mentioned multidiameter, and above-mentioned axle sleeve is pegged graft with the seat hole of sleeve block and cooperated; Above-mentioned ball-screw is connected with shaft sleeve key; Wherein, cooperate the taper roll bearing of pegging graft on the above-mentioned optical axis, above-mentioned taper roll bearing cooperates grafting with the seat hole.
As optimization, above-mentioned sleeve block one end face is bolted with end cap, and this end cap cooperates grafting with above-mentioned ball-screw.
As optimization, above-mentioned thrust ball bearing is arranged on the inner of the multidiameter of above-mentioned axle sleeve, and above-mentioned cylinder roller bearing is arranged on the end of the multidiameter of above-mentioned axle sleeve.
As optimization, the end of above-mentioned multidiameter is provided with annular groove, is provided with an opening baffle ring in this annular groove.
Three, the beneficial effect of the utility model
The internal structure of optimization means enables bigger carrying axial force and radial load and guarantees its works fine, increases its service life, reduces the maintenance cost of device and the replacement cost of parts.
Description of drawings
Below in conjunction with accompanying drawing the utility model leading screw feed arrangement is described further:
Fig. 1 is the explosive view of the utility model;
Fig. 2 is the perspective view of the utility model axle sleeve.
Among the figure, 1 is ball-screw, and 2 is axle sleeve, and 3 is sleeve block, and 4 is multidiameter, and 5 is optical axis, and 6 is thrust ball bearing, and 7 is cylinder roller bearing, and 8 is the seat hole, and 9 is taper roll bearing, and 10 is end cap, and 11 is annular groove, and 12 is baffle ring.
The specific embodiment
Embodiment one: as illustrated in fig. 1 and 2; The utility model leading screw feed arrangement includes ball-screw 1, axle sleeve 2 and sleeve block 3, and above-mentioned axle sleeve 2 one sides are multidiameter 4; Opposite side is an optical axis 5; Be plugged with thrust ball bearing 6 and cylinder roller bearing 7 on the above-mentioned multidiameter 4, above-mentioned thrust ball bearing 6 is arranged on the inner of the multidiameter 4 of above-mentioned axle sleeve 2, and above-mentioned cylinder roller bearing 7 is arranged on the end of the multidiameter 4 of above-mentioned axle sleeve 2.The end of above-mentioned multidiameter 4 is provided with annular groove 11; Be provided with an opening baffle ring 12 in this annular groove 11; Thrust ball bearing 6 and cylinder roller bearing 7 to being arranged on the multidiameter 4 have spacing effect, prevent in the middle of practical work process, because of vibrations produce axial relatively moving; Not only influence the operate as normal of device, and reduce the service life of its parts.
Above-mentioned axle sleeve 2 is pegged graft with the seat hole 8 of sleeve block 3 and is cooperated, and above-mentioned ball-screw 1 is connected with axle sleeve 2 keys, wherein, cooperates the taper roll bearing 9 of pegging graft on the above-mentioned optical axis 5, and above-mentioned taper roll bearing 9 cooperates grafting with seat hole 8.
Cooperate the thrust ball bearing 6 and the cylinder roller bearing 7 of pegging graft all to match with above-mentioned axle sleeve 2 with sleeve block 3; And in the middle of the utility model practical work process; When motor driven ball screws 1 is rotated; Axial force that is produced and radial load are carried by above-mentioned thrust ball bearing 6, cylinder roller bearing 7 and taper roll bearing 9 respectively, can play certain regulating action and at optical axis 5 ends of axle sleeve 2 taper roll bearing 9 is set, and can carry bigger radial load and axial force simultaneously.
Above-mentioned sleeve block 3 one end faces are bolted with end cap 10, and this end cap 10 cooperates grafting with above-mentioned ball-screw 1.In the middle of the course of work, end cap 10 can prevent effectively that axle sleeve 2 from producing axial relatively moving under ball-screw 1 drives.
