Abstract
The utility model discloses a roller crossed guide rail pair synchronizing with a retainer. The roller crossed guide rail pair synchronizing with the retainer comprises crossed guide rails and the retainer, wherein saw teeth are arranged on the contact surface portion of the crossed guide rails and the retainer, and a gear meshed with the saw teeth is arranged in the retainer. The retainer synchronizes with the crossed guide rails at any time and cannot be damaged, and therefore service life of the crossed guide rail pair is prolonged.
Description
Technical field
It is secondary that the utility model relates to a kind of cross-roller guide that can be reciprocating, and specifically a kind of cross-roller guide of retainer absolute synchronization is secondary.
Technical background
The cross-roller guide pair is comprised of two guide rails with V-type rolling channel, roller cage, cylindrical roller etc., and the cylindrical roller of cross arrangement is through reciprocating on the V-type rolling channel face of precision grinding mutually.Fig. 1 is the structural representation of existing cross-roller guide pair.Among Fig. 1, the 11st, cross slideway, the 12nd, retainer, the 13rd, postive stop baffle.The retainer 12 of cross-roller guide pair is being subjected to unidirectional effect of inertia or when vertically installing and using, because inertial force or action of gravitation, roller on the retainer and cross slideway 11 are prone to the slippage operation, asynchronous (paces are inharmonious) that causes retainer 12 and cross slideway 11, thereby may cause retainer to cross the stroke phenomenon, cause the postive stop baffle 13 of cross slideway to be interfered with retainer 12, easily affect the normal stressed operation of its cross slideway pair, even damage retainer.
Summary of the invention
It is secondary that the problem that exists in order to overcome prior art, the purpose of this utility model provide the synchronous cross-roller guide of a kind of retainer, and retainer is all synchronous with cross slideway at any time in this roller guide pair.
The purpose of this utility model is achieved through the following technical solutions:
The cross-roller guide pair that a kind of retainer is synchronous comprises cross slideway and retainer, and it is characterized in that: the surface of contact position with retainer on cross slideway is provided with sawtooth, is provided with the gear that is meshed with sawtooth in retainer.
In the utility model, gear can be one, is arranged on the intermediate portion of retainer.Gear also can for a plurality of, evenly be arranged in the retainer.
The utility model is by installing gear at the secondary retainer of cross-roller guide, and is provided with corresponding sawtooth at cross slideway, retainer and cross slideway assemble backgear can with cross slideway on engagement.Running principle according to the cross-roller guide pair, when not having slippage between roller and the cross slideway, roller operation on the retainer and 1/2 of the always cross slideway relative motion displacement of operation displacement of cross slideway, this is identical with engagement running principle on gear and the cross slideway, therefore move when the operation of retainer is with gear and interference phenomenon can not occur, the two can use jointly.And be that in the advantage of retainer increase gear the relative motion between gear and the cross slideway is the engagement operation, relative slippage can not appear, and gear is installed together with retainer, thereby can realize retainer and cross slideway absolute synchronization at any time.
Compared with prior art, the asynchronous problem that the utility model can thoroughly solve retainer and guide rail appearance realizes retainer and cross slideway absolute synchronization at any time; And retainer can not damage, and prolonged the working life of cross slideway pair.
Description of drawings
Fig. 1 is the structural representation of existing cross-roller guide pair.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is that the utility model middle gear is installed in the structural representation on the retainer.
Fig. 4 establishes serrate structural representation at cross slideway in the utility model.
Embodiment
The cross-roller guide pair that a kind of retainer described in the utility model is synchronous, Fig. 2 is structural representation of the present utility model.This cross-roller guide pair comprises cross slideway 1 and retainer 2, and the surface of contact position with retainer 2 on cross slideway 1 is provided with sawtooth 3, is provided with the gear 4 that is meshed with sawtooth 3 in retainer 2.
Fig. 3 is that the utility model middle gear is installed in the structural representation on the retainer.Fig. 4 establishes serrate structural representation at cross slideway in the utility model.By at the secondary retainer of cross-roller guide gear being installed, and be provided with corresponding sawtooth at cross slideway, retainer and cross slideway assemble backgear can with cross slideway on engagement.When not having slippage between roller and the cross slideway, retainer and gear move simultaneously, interference phenomenon can not occur, and the two can use jointly.And be that in the advantage of retainer increase gear the relative motion between gear and the cross slideway is the engagement operation, relative slippage can not appear, and gear is installed together with retainer, thereby can realize retainer and cross slideway absolute synchronization at any time.
