The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.
Fixed gear device of the present utility model is mainly for designing with cogged parts carry out tightening of wheel gear locking nut, the present embodiment is elaborated as an example of the steering pump in engine example, generally, steering pump gear is arranged on steering pump gear shaft in advance, general and the gear shaft spline fitted of steering pump gear again integral installation on engine, after steering pump gear is arranged on steering pump gear shaft, wheel gear locking nut has upper moment requirement, when tightening wheel gear locking nut, need fixed gear shaft, to reach the object of upper moment.The fixed gear device that the utility model provides rotates by fixed gear exactly, indirectly realizes fixing to gear shaft, and then tightens wheel gear locking nut.
As shown in Figures 1 and 2, the fixed gear device that the present embodiment provides, by being provided with main panel 11 in fixed mount 1 upper end, main panel 11 1 sides are provided with the gear axle journal breach 111 of stepping down, on main panel 11, be provided with two gear position limiting pieces 12 and fixture block 2, the axle journal of steering pump pushes the gear axle journal breach 111 of stepping down, gear inner face is just connected on main panel 11, two gear position limiting pieces 12 and fixture block 2 shape mated gear 62(are referring to Fig. 4) three-point fix, by the card base (21,21a) on fixture block 2, engage with gear teeth and reach the object of pinning gear rotation simultaneously.
Particularly, in such scheme, main panel 11 is fixed on base 14 by support bar 13, the similar U-shaped structure of base (referring to Fig. 3), and support bar 13 two ends are fixing by nut and base 14 and main panel 11, and base 14 is also bolted on workbench 5.The gear axle journal breach 111 of stepping down is located at main panel near a manually-operated side, convenient manually steering pump pushed to this gear axle journal and step down in breach 111 and gear inner face is connected on main panel 11, two gear position limiting pieces 12 are located at the gear axle journal breach 111 main panel upper surface around of stepping down, concrete setting position guarantees the three-point fix of two gear position limiting pieces 12 and fixture block 2 shape mated gears, in the present embodiment, two gear position limiting pieces 12 are located at gear axle journal step down left side and the top side of breach 111, fixture block 2 is located at the step down right side of breach 111 of gear axle journal, two gear position limiting pieces 12 can become for nylon, specifically be bolted on main panel 11.
For the card base rotation that prevents fixture block 2 is stepped down breach distance too closely and then is interfered pushing of steering pump apart from gear axle journal, fixture block 2 rotates within the specific limits around rotating shaft 23, particularly, near the main panel upper surface place of fixture block 2, be provided with the spacer pin 4 that restriction fixture block rotates, in the present embodiment, the set bolt of main panel 11 also can play the effect that is similar to spacer pin 4, when fixture block 2 arrives certain position along B to rotation (referring to Fig. 5), spacer pin 4 stops it to continue rotation, on the contrary, the set bolt of the close fixture block 2 of main panel 11 also stops fixture block 2 to continue rotation to the opposite direction of B.
As shown in Figure 4, when concrete this device of use, first, by bolt, this device is fixed on to (referring to Fig. 2) on work top.Secondly, gear 62 is contained on the gear shaft 61 of steering pump 6, after wheel gear locking nut 63 pretensions, along gear axle journal breach 111 opening directions of stepping down, push the inner surface of gear 62 is connected on main panel 11, when gear is encountered after fixture block 2, fixture block 2 23 clockwise rotate around the shaft (referring to Fig. 5 B to), under the tension force effect of spring 3, fixture block 2 self-returns, the support zone 22 of the forward card base 21 on fixture block 2 is connected to certain gear teeth forward face (referring to Fig. 5), by moment on torque spanner, rotate clockwise, the oriented trend clockwise rotating of gear 62, promote the trend that fixture block 2 rotates counterclockwise, gear 62 forms and is automatically locked with fixture block 2.
In like manner, in the time of need to unclamping wheel gear locking nut moment, fixture block 2 is toggled it to limited block 4 places clockwise, under the tension force effect of spring 3, fixture block 2 gear that is automatically locked rotates counterclockwise, and meets the condition of the locking nut moment that gets loose counterclockwise.Finally, steering pump is upwards mentioned certain distance, and gear 62 departs from fixture block 2 dislocation, and steering pump can freely take out and lift down from this device.
Gear fixing device of the present utility model is by arranging the fixture block of flexible rotating, there is the gear of being automatically locked, fixture block is under the tension of spring, in certain space, can rotate freely around the shaft, one direction is stepped down to gear, the locked gear of one direction, stir the position of fixture block, can realize clockwise and locked conversion counterclockwise.Meanwhile, this apparatus structure is simple, and manufacturing process is succinct, only needs simple car, brill, cuts with scissors, attacks, welds and can complete processing and manufacturing, cost-saving, and, can realize quick and convenient installation steering pump gear, to raise the efficiency, reduction process consumes, and reduces labour intensity.
Disclosed is above only specific embodiment of the utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
