Abstract
The utility model relates to a moment of torsion angle sensor's installation assembly technical field, specific saying is a gear fixed knot constructs for moment of torsion angle sensor, and the gear installing zone is fixed on plastic housing, is equipped with the buckle respectively around the gear installing zone, and the buckle is also fixed on plastic housing, V type opening has been seted up to the bottom of gear installing zone for gear installing zone bottom forms a V type shell fragment of connection in the gear installing zone bottom surface, the most advanced of V type shell fragment and the coincidence of the central point of gear installing zone are fixed with the boss in the most advanced top of V type shell fragment, the utility model discloses a fixed mode of buckle and bottom shell fragment has cancelled the plastic end cover to and complicated elastic construction in the plastic end cover, effectively reduce the cost, simplified the assembly process simultaneously.
Description
Technical Field
The utility model relates to a moment of torsion angle sensor's installation assembly technical field, specific saying is a gear fixed knot constructs for moment of torsion angle sensor.
Background
The magnet driven gear of the existing angle sensor is placed in the mounting hole of the plastic shell, the plastic cover is mounted at the top, an elastic structure is arranged in the plastic cover to compress the top of the magnet driven gear for fixing, and particularly, the elastic structure is complex in shape and high in production cost, and the cost of the plastic cover is also high, so that the overall cost of the torque angle sensor is high.
For this reason, it is necessary to design a gear fixing structure for a torque angle sensor that is low in cost and easy to install.
Disclosure of Invention
The utility model discloses a prior art's a difficult problem has been broken through, a gear fixed knot who is used for moment of torsion angle sensor that low-cost easily installs constructs has been designed.
In order to achieve the above object, the utility model provides a gear fixed knot constructs for moment of torsion angle sensor, including plastic housing, gear installing zone, buckle, its characterized in that: the gear installing area is fixed on the plastic shell, buckles are arranged on the periphery of the gear installing area respectively and are also fixed on the plastic shell, a V-shaped opening is formed in the bottom of the gear installing area, a V-shaped elastic sheet connected to the bottom surface of the gear installing area is formed at the bottom of the gear installing area, the tip of the V-shaped elastic sheet coincides with the central point of the gear installing area, and a boss is fixed above the tip of the V-shaped elastic sheet.
The number of the buckles is 3, and the distribution positions are rotationally symmetrical about the center point of the gear installation area.
The gear mounting area and the plastic shell are of an integrated structure.
Compared with the prior art, the utility model, adopt the fixed mode of buckle and bottom shell fragment, cancelled the plastics end cover to and complicated elastic construction in the plastics end cover, effectively the cost is reduced has simplified the assembly process simultaneously.
Drawings
Fig. 1 is a schematic view of a fixed structure of a gear in the prior art.
Fig. 2 is a schematic structural diagram of the present invention.
Fig. 3 is a partial cross-sectional view of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 2, the utility model discloses a gear fixed knot constructs for moment of torsion angle sensor, including plastic housing 7, gear installing zone 1, buckle 2, gear installing zone 1 is fixed on plastic housing 7, is equipped with buckle 2 around the gear installing zone 1 respectively, and buckle 2 also fixes on plastic housing 7, V type opening 3 has been seted up to the bottom of gear installing zone 1 for 1 bottom of gear installing zone forms a V type shell fragment 4 of connecting in 1 bottom surface of gear installing zone, the coincidence of the most advanced and the central point of gear installing zone 1 of V type shell fragment 4 is fixed with boss 5 in the most advanced top of V type shell fragment 4.
The utility model discloses well buckle 2's quantity is 3, and the distribution position is then about 1 central point rotational symmetry in gear installation district for 6 axial spacing fastenings of magnet driven gear prevent that magnet driven gear 6 from taking place to rock the scheduling problem.
The utility model discloses well gear installation district 1 and plastic casing 7 formula structure as an organic whole for the gear installation district is fixed inseparable, lets gear installation district 1 also be plastic material simultaneously, thereby makes V type shell fragment 4 can compensate because the gear deflection that plastic sheet manufacturing tolerance arouses, the jamming risk that probably produces when eliminating gear revolve.
In specific implementation, after the magnet driven gear 6 is pressed into the gear mounting area 1, the three buckles 2 buckle the top of the gear 6, the boss 5 on the V-shaped elastic sheet 4 is extruded by the bottom of the gear 6, and the boss 5 and the buckles 2 jointly axially fix the gear 6; the V-shaped elastic sheet 4 can compensate the gear deflection caused by the manufacturing tolerance of the plastic sheet, and the clamping risk which is possibly generated when the gear rotates is eliminated.
