Abstract
The utility model relates to an eccentric gear type wheel, gear body including cylindrical second grade echelonment, gear body integrated into one piece, gear body axial middle part is equipped with the shaft hole, be equipped with the teeth of a cogwheel on the outer circumference of one end that the external diameter is little, radially be equipped with several screw through -hole on the outer circumference of one end that the external diameter is big, the screw thread through -hole has 3 or 4, and the symmetry sets up. The utility model discloses an eccentric gear type wheel simple structure connects stably, the transmission good reliability, and the transmission is stable, and long service life.
Description
Technical field
This utility model relates to a kind of actuating device, particularly to a kind of centering type gear, belongs to plant equipment manufacture and adds
Work technical field.
Background technology
Gear is the mechanical organ having tooth can engage transmitting movement and power continuously on wheel rim, plays biography in plant equipment
Action is used.Gear by with other dentation machine components (such as another gear, tooth bar, worm screw) transmission, can realize change rotating speed with
The functions such as moment of torsion, the change direction of motion and change forms of motion.Owing to transmission efficiency is high, gear ratio is accurate, power bracket is big
Advantage, gear mechanism extensively applies in industrial products, and its design and manufacture level directly influence the quality of industrial products.Tooth
The wheel gear teeth mutually clasp gear and another pinion rotation can be driven to transmit power.By two gears separately, it is also possible to application chain
Bar, crawler belt, belt drive the gear on both sides to transmit power.It is therefore necessary to ensure reliability of gears is good, stable transmission, make
Use the life-span long, it is therefore necessary to improve the structure of centering type gear to reach required performance requirement.
Utility model content
This utility model purpose is to propose a kind of stable transmission and service life to overcome the deficiencies in the prior art
Long centering type gear.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of centering type gear, including cylindrical two
The stair-stepping gear of level；Described gear is one-body molded；Described gear axially middle part is provided with axis hole；Described external diameter
It is toothed around on little one end excircle；It is radially provided with several tapped through hole on one end excircle that described external diameter is big；Described take turns
Tooth module is 0.75, and the number of teeth is 24, and pressure angle is 20 °, and helical angle is 15 °.
Preferably, the two ends of described axis hole are provided with 45 and spend and cross chamfering.
Preferably, described tapped through hole has 3 or 4, and is symmetrical arranged.
Preferably, described gear surface hardening, hardness is HRC47 ~ 52.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
Centering type gear structure of the present utility model is simple, and reliable transmission is good, stable transmission, and service life is long.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1, gear；2, axis hole；3, the gear teeth；4, tapped through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of centering type gear of the present utility model, as shown in Figure 1, including cylindrical two grades of stair-stepping gear
1；Described gear 1 uses integral molding techniques；Described gear 1 axially middle part is provided with axis hole 2；Described external diameter little one
It is toothed around 3 on end excircle；Several tapped through hole 4 it is radially provided with on one end excircle that described external diameter is big；The described gear teeth 3 mould
Number is 0.75, and the number of teeth is 24, and pressure angle is 20 °, and helical angle is 15 °.
Further instruction, the two ends of described axis hole are provided with 45 and spend and cross chamfering.
Further instruction, described tapped through hole has 3 or 4, and is symmetrical arranged so that gear is with other accessories even
When connecing more stable.
Further instruction, described gear surface hardening, hardness is HRC47 ~ 52, wear-resistant, effectively extends use
Life-span.
Centering type gear structure of the present utility model is simple, installs stable, and reliable transmission is good, stable transmission, and uses
Life-span is long.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limit
System.All employing equivalents or equivalence are replaced and the technical scheme that formed, all fall within this utility model rights protection scope it
In.
