Abstract

The utility model belongs to the field of mechanical transmission and relates to an assembled type gear. The assembled type gear disclosed by the utility model comprises a gear plate, a gear ring arranged at an outer ring of the gear plate and a shaft hole formed in the centre of the gear plate, wherein the gear plate and the gear ring are separated structures; the gear ring comprises a large half gear ring and a small half gear ring; and the large half gear ring and the small half gear ring are separated structures. After the gear disclosed by the utility model is damaged, the gear ring is only replaced, so that the waste of the resources is reduced and the cost is reduced; when the damaged gear ring is disassembled, the small half gear ring is separated from the large half gear ring, and then the large half gear ring is separated from the gear plate, the large half gear ring is radially disassembled and the disassembly is finished; and the gear disclosed by the utility model is convenient to disassemble, so that the maintaining time is reduced.

Description

A kind of assembly type gear

Technical field

The utility model belongs to mechanical transmission fields, relates to a kind of assembly type gear.

Background technique

Gear transmission is most widely used a kind of type of belt drive in mechanical transmission.After being contained in gear in machine and using through long-term work, gear tends to damaged, as spot corrosion, gummed, wearing and tearing, broken teeth etc.Make between driving gear, intermediate gear and driven gear engagement bad, tooth pushing or hypodontia phenomenon can occur, need to shut down and change, because traditional integral gear cost is higher, need whole gear is changed once damaging, cause the wasting of resources, the cost raising.Conventional gears the time need to disassemble axle in dismounting, then with gear shaft to dismounting, inevitably just need a large amount of associated components is disassembled simultaneously, this dismounting and the process that re-assemblies extremely bother, the replacing time is longer, has reduced working efficiency.

The model utility content

The purpose of this utility model is will solve the deficiencies in the prior art part and a kind of assembly type gear is provided.More gear changing only need be changed gear ring, and Cost reduction, and convenient disassembly have shortened engineering time.

A kind of assembly type gear, comprise wheel disc, be located at the wheel disc outer ring gear ring, be located at the wheel disk center axis hole, it is characterized in that: described wheel disc and gear ring are detachable structure; Described gear ring comprises large half-ring gear and little half-ring gear, and large half-ring gear and little half-ring gear are detachable structure.

Wheel disc cylindrical wall described in the utility model is provided with draw-in groove one, and described large half-ring gear inner round wall is provided with projection one, and wheel disc is fixedly connected with projection one by draw-in groove one with large half-ring gear; Described large half-ring gear sidewall is provided with draw-in groove two, and smaller part gear ring sidewall is provided with projection two, and large half-ring gear is fixedly connected with projection two by draw-in groove two with little half-ring gear.

Gear ring described in the utility model cross section is trapezoidal, on one side the gear ring inwall has inwall prolonged section vertically, inside wall height and wheel disc height equate and greater than the width of the gear teeth on gear ring; Respectively have a through hole on the inwall prolonged section of large half-ring gear and on the inwall prolonged section of little half-ring gear, have two apertures corresponding with through hole on gear ring on wheel disc.

Smaller part gear ring length described in the utility model is greater than shaft hole diameter length.

The utility model also includes the screw that matches with aperture with through hole.

Compared to the prior art the utlity model has following characteristics and beneficial effect:

1, gear described in the utility model after damage, only need to replace gear ring, has reduced the waste of resource, has reduced cost.

2, when removing damaged gear ring, the projection two of smaller part gear ring sidewall is shifted out the draw-in groove two of large half-ring gear sidewall, large half-ring gear is separated with the smaller part gear ring, then the projection one on large half-ring gear inner round wall is shifted out draw-in groove one on wheel disc, radially remove again large half-ring gear, namely complete dismounting.Convenient disassembly has reduced engineering time.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details.

Embodiment, see Fig. 1, Fig. 2, shown in Figure 3:

A kind of assembly type gear, comprise wheel disc 1, be located at wheel disc 1 outer ring gear ring 2, be located at the axis hole 3 at wheel disc 1 center.Described wheel disc 1 and gear ring 2 are separable.When the gear teeth are damaged, can only disassemble gear ring 2; Described gear ring 2 comprises large half-ring gear 4 and smaller part gear ring 5, and large half-ring gear 4 and smaller part gear ring 5 are separable.

Wheel disc 1 cylindrical wall is provided with draw-in groove 1, and described large half-ring gear 4 inner round wall are provided with projection 1, and wheel disc 1 is fixedly connected with projection 1 by draw-in groove 1 with large half-ring gear 4; Described large half-ring gear 4 sidewalls are provided with draw-in groove 28, and smaller part gear ring 5 sidewalls are provided with projection 29, and large half-ring gear 4 is fixedly connected with projection 29 by draw-in groove 28 with smaller part gear ring 5.

When removing damaged gear ring 2, the projection 29 of smaller part gear ring 5 sidewalls is shifted out the draw-in groove 28 of large half-ring gear 4 sidewalls, large half-ring gear 4 is separated with smaller part gear ring 5.Greater than axis hole 3 diameter lengths, the gap width of large half-ring gear 4 is greater than the diameter of axle due to smaller part gear ring 5 length, thus the projection 1 on large half-ring gear 4 inner round wall is shifted out draw-in groove 1 on wheel disc 1, more radially remove large half-ring gear 4, namely complete dismounting.Convenient disassembly has reduced engineering time.

Gear ring 2 cross sections are trapezoidal, on one side gear ring 2 inwalls have inwall prolonged section 10 vertically, inside wall height and wheel disc 1 highly equate and greater than the width of the gear teeth on gear ring 2; Respectively have a through hole 11 on the inwall prolonged section of large half-ring gear 4 and on the inwall prolonged section of smaller part gear ring 5, have on wheel disc 1 with gear ring 2 on two corresponding apertures 12 of through hole 11.After the good wheel disc of assembly unit 1 and gear ring 2, then will fix the position of through hole 11 and aperture 12 with the screw 13 that matches, and make gear be unlikely to sidesway occurs in operation process and machinery is broken down.
