Abstract
The utility model discloses a gear which comprises a first gear, a second gear, a gear sleeve and a gear shaft. The gear sleeve is sleeved with the first gear and the second gear, and the diameter of the first gear is larger than that of the second gear. The gear shaft is sleeved with the gear sleeve, and the gear sleeve and the gear shaft relatively rotate. The first gear is composed of a left half wheel and a right half wheel, the upper end and the lower end of the left half wheel are respectively provided with a protrusion, the upper end and the lower end of the right half wheel are provided with grooves, the protrusions and the grooves are matched, and the protrusions are embedded in the grooves to enable the left half wheel and the right half wheel to be closely connected. According to the gear, after the first gear is worn, fast dismounting can be achieved through the structure of the protrusions and the grooves, dismounting time is saved, and working efficiency and the device use ratio are improved.
Description
Technical field
The utility model relates to a kind of mechanical parts, relates in particular to a kind of gear.
Background technique
Gear is one of mechanical parts commonly used, and gear is owing to being often used in drive mechanism, and the rate of wear is fast, needs periodic replacement, and the replacing of gear need to be by whole gear disassembling, cumbersome.
The model utility content
The purpose of this utility model: a kind of gear is provided, can helps to reduce dismounting and time of gear changing more, improve Utilization ratio.
To achieve these goals, the technical solution of the utility model is:
A kind of gear, comprise the first gear, the second gear, geared sleeve and gear shaft, described the first geared sleeve is located on described geared sleeve, and described the second geared sleeve is located on described geared sleeve, and the diameter of described the first gear is greater than the diameter of described the second gear; Described geared sleeve is set on described gear shaft, and described geared sleeve and described gear shaft relatively rotate; Described the first gear consists of a left side half wheel and right half wheel, upper end and the lower end of a described left side half wheel are respectively equipped with projection, upper end and the lower end of the described right side half wheel are provided with groove, described projection and groove are suitable, and described projection is embedded in described groove a described left side half wheel closely is connected with right half wheel.
Above-mentioned gear, wherein, described projection and groove are trapezium structure.
Above-mentioned gear, wherein, the external tooth of described the first gear and the second gear is snail face tooth.
Above-mentioned gear, wherein, described the first gear, the second gear, geared sleeve and gear shaft in the axial direction be projected as concentric circle.
Above-mentioned gear, wherein, a described left side half wheel and right half wheel are respectively equipped with spring sheet with the joint of described geared sleeve.
The utility model can utilize the structure quick-detachment of projection and groove after the first gear wear, has saved the take-down time, has improved the utilization ratio of working efficiency and equipment.
The accompanying drawing explanation
Fig. 1 is the plan view of the utility model gear.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Refer to shown in accompanying drawing 1, a kind of gear, comprise the first gear 1, the second gear 2, geared sleeve 3 and gear shaft 4, described the first gear 1 is set on described geared sleeve 3, described the second gear 2 is set on described geared sleeve 3, and the diameter of described the first gear 1 is greater than the diameter of described the second gear 2; Described geared sleeve 3 is set on described gear shaft 4, and described geared sleeve 3 relatively rotates with described gear shaft 4; Described the first gear 1 by a left side partly take turns 11 and the right side partly take turns 12 and form, 11 upper end is partly taken turns on a described left side and lower end is respectively equipped with projection 5, the described right side is partly taken turns 12 upper end and lower end and is provided with groove 6, described protruding 5 is suitable with groove 6, described protruding 5 are embedded in described groove 6 and make a described left side partly take turns 11 partly to take turns 12 with the right side and closely be connected, convenient disassembly.
Described protruding 5 and groove 6 be trapezium structure, can make a left side partly take turns 11 and the right side partly take turns 12 and keep closely connecting in operation process.
The external tooth of described the first gear 1 and the second gear 2 is snail face tooth, can be used in conjunction with less worm screw.
Described the first gear 1, the second gear 2, geared sleeve 3 and gear shaft 4 in the axial direction be projected as concentric circle.
A described left side partly takes turns 11 and right partly take turns 12 and be respectively equipped with spring sheet 7, friction and pressure between available buffer the first gear 1 and geared sleeve 3 with the joint of described geared sleeve 3.
In sum, the utility model can utilize the structure quick-detachment of projection and groove after the first gear wear, has saved the take-down time, has improved the utilization ratio of working efficiency and equipment.
