Abstract
The utility model relates to a double-nut gasket pre-tightened ball lead screw pair, which is provided with a threaded lead screw, wherein a first nut and a second nut are sleeved on the lead screw; an adjusting gasket is mounted between the first nut and the second nut; the adjusting gasket is sleeved on the lead screw; and an outer ring of the first nut and an outer ring of the second nut are connected through a connecting strip. As the first nut and the second nut are drawn nearer through the adjusting gasket, the first and the second nuts can operate stably with the lead screw, and the service life of the ball lead screw pair is prolonged.
Description
Technical field
The utility model relates to the ball screw pair technical field, especially relates to a kind of double nut pad pretension ball screw pair.
Background technique
Conventional double nut ball screw pair is after long-term the use, and ball is that steel ball is easy to wear, causes between nut and the nut, is connected between nut and the leading screw and the space occurs, the lead screw pair fluctuation of service.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of double nut pad pretension ball screw pair is provided, adopt the pretension means between nut and the nut, even worn steel ball also can stable for a long time use.
The utility model solves the technological scheme that its technical problem adopted: a kind of double nut pad pretension ball screw pair; Has threaded leading screw; Described leading screw is with first nut, second nut; Between described first nut and second nut adjustment pad is installed, the adjustment pad is enclosed within on the leading screw, and the described first nut outer ring is connected by connection strap with the second nut outer ring.
The beneficial effect of the utility model is: after between the utility model first nut and second nut adjustment pad being installed; In long-term using process, even the steel ball between first nut or second nut and the leading screw has a little wearing and tearing, between first nut and second nut space appears; Can the adjustment pad; The further distance of first nut and second nut, making still can be stable between the nut of winning, second nut and the leading screw, prolongs the working life of ball screw pair.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Wherein: 1. leading screw, 2. first nut, 3. second nut, 4. adjustment pad.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1; A kind of double nut pad pretension ball screw pair; Have threaded leading screw 1, leading screw 1 is with adjustment pad 4 is installed between first nut 2, second nut, 3, the first nuts 2 and second nut 3; Adjustment pad 4 is enclosed within on the leading screw 1, and first nut, 2 outer rings are connected by connection strap with second nut, 3 outer rings.
After between first nut 2 and second nut 3 adjustment pad 4 being installed; In long-term using process, even the steel ball between first nut or second nut and the leading screw has a little wearing and tearing, between first nut 2 and second nut 3 space appears; Can adjust pad 4; The further distance of first nut 2 and second nut 3 makes that win still can be stable between nut 2, second nut 3 and the leading screw 1, prolongs the working life of ball screw pair.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
