Abstract
The invention discloses a synchronous roller cross guide rail pair for a retainer. The synchronous roller cross guide rail pair comprises a cross guide rail and a retainer, wherein sawteeth are formed on a contact surface part of the cross guide rail and the retainer; and a gear meshed with the sawteeth is arranged in the retainer. The retainer is synchronous with the cross guide rail at any moment, the retainer is prevented from being damaged, and the service life of the cross guide rail pair is prolonged.
Description
Technical field
It is secondary to the present invention 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
The problem that exists in order to overcome prior art, it is secondary to the purpose of this invention is to 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 objective of the invention is to be 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.
Among the present invention, 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 present invention 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 present invention can thoroughly solve the asynchronous problem of 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 invention.
Fig. 3 is that middle gear of the present invention is installed in the structural representation on the retainer.
Fig. 4 establishes serrate structural representation at cross slideway among the present invention.
Embodiment
The cross-roller guide pair that a kind of retainer of the present invention is synchronous, Fig. 2 is structural representation of the present invention.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 middle gear of the present invention is installed in the structural representation on the retainer.Fig. 4 establishes serrate structural representation at cross slideway among the present invention.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.
