【Specific implementation mode】
Be described in detail the utility model below in conjunction with attached drawing and specific embodiment, illustrative examples therein with
And explanation is only used for explaining the utility model, but be not intended to limit the scope of the present invention.
It please refers to Fig.1 and Fig. 2, the gear speed sensor of the utility model is used for the speed of induction gear 200.It is described
Gear speed sensor is installed on motor and includes shell 100 and electronic component (not shown).The shell 100 includes cavity
10 and partition board 20, the cavity 10 is divided into first part 12 and second part 14 by the partition board 20, and the gear 200 is installed
In the first part 12, and the gear 200 is axially and radially all with having gap, the electronics member between shell 100
Device is installed on the second part 14, and the shell 100 is equipped with mounting surface 30, and the gear speed sensor further includes sealing
It encloses (not shown), the sealing ring is installed on mounting surface 30 with sealed electric-motor, in 14 encapsulating of second part to seal the electronics
Component, to improve the waterproofing grade of the gear speed sensor.
In the present embodiment, the gear speed sensor is installed on back end cover for motor, and sealing ring is located at gear speed
Between sensor and back end cover for motor, for preventing water from entering motor.
Because of sealant pouring and sealing electronic component, and sealing ring seals motor, to greatly improve this gear speed
The waterproof effect of sensor, improves waterproofing grade.
In the present embodiment, gear speed sensor water-proof grade is IP68.
Because partition board 20 separates gear 200 and electronic component, that is, by the element for needing waterproof and waterproof is not needed
Element separate, to only needing to do part waterproof, without to entire shell waterproof, reducing waterproof cost, also improving
Waterproof effect.
Meanwhile because the gear 200 is axially and radially all with having gap, i.e. the utility model solution between shell 100
Determined it is existing in the art, the problem of 200 shell 100 easy to wear of gear.
Referring to FIG. 5, gap between 100 bottom of the gear 200 and shell be more than 200 vibration of the gear away from
From to prevent gear 200 from wearing shell 100.That is, gear 200, in normal transmission range, gear 200 all will not
Shell 100 is worn, the service life of gear speed sensor is improved.
In the present embodiment, after installation, the gap between 100 bottom of gear 200 and shell is 5.5~8.5mm, long-range
In vibration distance --- 0~1.2mm of gear 200.
It please refers to Fig.1 to Fig. 5, the shell 100 is equipped with multiple lugs 40, each lug 40 is equipped with mounting hole 42, uses
In fixed gear speed sensor.
In the present embodiment, lug 40 is 2~4, and gear speed sensor is installed on motor rear end by screw
Lid, simplifies the structure that gear speed sensor is installed on motor, reduces cost.
Further, the shell 100 is equipped with hollow strengthening portion 50, and the strengthening portion 50 is from the bottom of shell 100 to peace
Dress face 30 is protruded, for preventing shell 100 from deforming.
Because 10 inside of cavity is dissymmetrical structure, it is easily deformed during production.Under normal circumstances, shell 100
It is easy to become ellipse from circle, because there is the presence of strengthening portion 50, balances the structure of the cavity 10 in shell 100, prevent
Shell 100 becomes ellipse from circle, and the gear being installed in cavity 10 200 has been further prevented to wear shell 100.
Further, the volume of the first part 12 is more than the volume of second part 14, and the strengthening portion 50 is located at first
Part 12.
Further, electronic component includes test the speed component and cable, component and the cable fixation company of testing the speed
It connects and is installed on second part 14.
Further, electronic component further includes pcb board, magnet steel and chip, and the shell 100 is equipped with positioning region 60, described
Positioning region 60 is located at second part 14, for positioning pcb board, magnet steel and chip.
Because second part 14 is by sealant pouring and sealing, i.e. electronic component in this case is outer to be installed on by sealant pouring and sealing
Electronic component in shell 100 is not easy, into water, to improve waterproof effect.
Further, the shell 100 is additionally provided with a pair of of pilot pin, and the pilot pin is located at the both sides of the positioning region 60,
The pcb board, magnet steel and chip are installed on pilot pin.
Further, partition board 20 be arc-shaped, with prevent gear 200 abrasion test the speed component, cable, pcb board, magnet steel and
Chip.
Because the component that tests the speed, cable, pcb board, magnet steel and the chip and gear 200 of gear speed sensor are by partition board 20
Isolation, to which during gear 200 operates, the component that tests the speed, cable, pcb board, magnet steel and chip etc. will not be may wear to
Other elements, to protect the other elements of gear speed sensor.
Referring to FIG. 3, the shell 100 is equipped with outlet hole 70, the outlet hole 70 is located at second part 14 and passes through chamber
Body 10 extends to the outside of shell 100, and the cable is stretched out by outlet hole 70 outside cavity 10, to prevent the cable from rolling over
It is disconnected.
And because second part 14 is by sealant pouring and sealing, water is not easy to enter second part 14 by outlet hole 70, into one
Step improves the waterproof ability of gear speed sensor.
Because cable is pierced by by outlet hole 70 from cavity 10, to prevent fractureing for cable, reduce cable
The maintenance and repair of line, improve the service life of gear speed sensor.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
