Description
Technical field
The utility model relates to a kind of mechanical transmission component technical field, particularly relates to a kind of double nut rotating feed mechanism.
Background technique
Nut rotating feed mechanism is widely used in the transmission device of carrying Long travel.Existing nut rotating feed mechanism generally adopts single nut rotating feed mechanism, and single nut rotating feed mechanism comprises nut and is set in the screw mandrel on nut, and as shown in Figure 1, its technological core is that nut is fixed, and is rotated reach feeding by screw mandrel.But there is following subject matter in single nut rotating feed mechanism: one is that the rotary screw that works long hours easily causes wire rod thread to wear and tear, simultaneously between nut thread and rolling ball bearing because wearing and tearing also easily produce gap, cause mechanical transmission positioning precision poor; Two is that single nut rotating feed mechanism can only the precompressed of fixing property, cannot the precompressed of adjusting property, and owing to using the lathe of this mechanism to be all Long travel and high load, causing after long-time use cannot Adjustment precision, and maintenance difficult.
Summary of the invention
The utility model adopt that nut is fixed, screw mandrel swivel feeding easily causes wire rod thread to wear and tear for single nut rotating feed mechanism in prior art and between nut thread and rolling ball bearing because of wearing and tearing also easily produce gap, single nut rotating feed mechanism can only fixing property precompressed and cannot the shortcoming of adjusting property precompressed, provides a kind of screw mandrel to fix and nut rotates, has the double nut rotating feed mechanism of scalability precompressed.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Double nut rotating feed mechanism, the screw mandrel comprising the bearing be set on nut seat, be set in the nut on bearing and be located at by external thread sleeve on nut, nut comprises the first nut and the second nut, first nut or the second nut sleeve are located on bearing, be arranged with the precompressed adjustment ring for the first nut and the second nut swivel feeding between first nut and the second nut, screw mandrel is through the first nut, precompressed adjustment ring and the second nut.
Screw mandrel is fixed, nut swivel feeding, comes adjusting play by precompressed adjustment ring.
As preferably, the first nut sleeve is located on bearing, and the first nut is driven by belt pulley, and belt pulley comprises the follower that is connected with the first nut and the driving wheel by belt drive follower, and driving wheel is connected with speed reducer, and speed reducer is driven by motor.
As preferably, nut outer end is arranged with sleeve.
The utility model is owing to have employed above technological scheme, there is significant technique effect: adopt screw mandrel to fix and nut rotates, by arranging precompressed adjustment ring between double nut, precision precompressed adjustment when Long travel, high load swivel feeding can be met, and scalability precompressed can ensure the simple-to-maintain after long time running, continue to keep mechanical precision stability, the modular design of integrated type nut and sleeve, substantially increases manufacturing efficiency and considerably reduces cost of production.
