Abstract
The utility model relates to a worm wheel supporting device used for a vehicle steering column lock. The worm wheel supporting device comprises a casing, and a worm wheel and bearings which are arranged in an inner cavity of the casing, and is characterized in that the bearings are arranged at two axial end of the worm wheel, a dummy club is arranged in the inner cavity of the casing, a bearing mounting groove arranged on the dummy club is matched and connected with one bearing, and the other bearing is matched and connected with a bearing seat arranged on a casing cover. The worm wheel supporting device can be used for effectively improving the torque transfer efficiency, and the rationality of assembly process is achieved.
Description
Technical field
The utility model relates to a kind of worm gear bearing device that steering column for vehicle is locked that is used for.
Background technique
In recent years, have many vehicles to adopt the one-touch key starting system of exempting from both at home and abroad, wherein exempting from the key release is to provide power by motor with the steering column for vehicle lock of locking, through the worm gear worm gear reducer.In order to improve the rationality of moment of torsion transmission efficiency and realization assembly technology, this programme promptly is for realizing that this purpose proposes.
Summary of the invention
The purpose of this utility model is to provide a kind of worm gear bearing device that steering column for vehicle is locked that is used for, and this device effectively improves the moment of torsion transmission efficiency and realizes the rationality of assembly technology.
Of the present utility model being characterised in that: a kind ofly be used for the worm gear bearing device that steering column for vehicle is locked, comprise housing and worm gear, the bearing of being located at the housing inner chamber, it is characterized in that: described worm-wheel shaft is provided with bearing to two ends, described housing inner chamber is provided with a boss, offer the Bearing Installation groove on the described boss and a bearing is connected, another bearing is connected with the bearing support that is opened on the cap.
Advantage of the present utility model: simple and reasonable, be installed on convenient disassembly, time saving and energy saving, maintenance or replacing component are rapid and simple, have also improved the efficient that moment of torsion transmits simultaneously.
Description of drawings
Fig. 1 is component assembly technology figure of the present utility model.
Fig. 2 is a structure cutaway view of the present utility model.
Among the figure: 1 is housing; 2 is worm gear; 3 is bearing; 4 is cap; 11 is boss; 12 is the Bearing Installation groove; 41 is bearing support.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperate appended graphic being described in detail below.
With reference to figure 1 and Fig. 2, a kind ofly be used for the worm gear bearing device that steering column for vehicle is locked, comprise housing 1 and worm gear 2, the bearing 3 of being located at housing 1 inner chamber, it is characterized in that: described worm gear 1 axial two ends are provided with bearing 3, described housing 1 inner chamber is provided with a boss 11, offer Bearing Installation groove 12 on the described boss 11 and a bearing 3 is connected, another bearing 3 is connected with the bearing support 41 that is opened on the cap 4.
The standard pitch diameter of above-mentioned worm gear 2 equates with the external diameter of bearing 3.
Above-mentioned bearing 3 is a deep groove ball bearing.
The utility model is made up of housing, bearing, worm gear, cap.Its assembly technology: earlier bearing is pressed on the axle sleeve that is connected the worm gear two ends, then the assemblying body of bearing and worm gear is inserted in the Bearing Installation groove of housing, lock cap at last, supporting bearing, the rationality that this can improve the moment of torsion transmission efficiency and realize assembly technology by housing and cap.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
