Description
Technical field
The utility model relates to a kind of industrial machinery technical field, specifically is the tooth-like plane table thermoconductivity meter of a kind of difference.
Background technique
Existing retarder will lean on the bigger gear of many group diameter difference could accomplish the high power deceleration, and the retarder volume is relatively large, because volume is big, parts are many, cost is relatively just high, and inconvenience is arranged in actual use more.
The model utility content
The technical problem that the utility model will solve provides the tooth-like plane table thermoconductivity meter of difference that a kind of volume is little, parts are few, cost is low, cost performance is high, the deceleration multiple is high.
The utility model solves the problems of the technologies described above with following technological scheme: the tooth-like plane table thermoconductivity meter of a kind of difference; By spragging gear; Output gear, power output semiaxis, left lateral star gear, right lateral star gear, planet pin, braking semiaxis, Brake drum, drive wheel, braking device, equilibrate counterweight, gear box casing, bearing support and rack form
Concrete structure and Placement are:
Left lateral star gear and right lateral star gear be installed on the planet pin with spline and the Bearing Installation through two ends in the speed reducer inner walls; Equilibrate counterweight is installed in the lower end of speed reducer inner walls; Spragging gear is installed on the braking semiaxis; Output gear is installed on the power output semiaxis; Braking semiaxis and power output semiaxis respectively through Bearing Installation on speed reducer housing right ends bearing support and be fixed on the frame, brake the semiaxis left end Brake drum and braking device be installed, drive wheel is installed on the reducer shell.
The number of teeth of said spragging gear and output gear differs 1～3 tooth.It is more little to differ the number of teeth, and reduction speed ratio is big more.
Said speed reducer housing is that to export semiaxis with braking semiaxis and power be the cylindrical box in the center of circle.
Said left lateral star gear and right planetary module, diameter are decided according to the concrete design data of spragging gear and output gear: the diameter difference of spragging gear and output gear is more little, its reduction speed ratio is just big more, and is opposite with the installation method effect of routine;
Said drive wheel is gear, belt pulley or chain drum.
Outstanding substantive distinguishing features and the remarkable progress of the utility model is:
1, the deceleration multiple is high.Retarder deceleration multiple reaches 7.5 times, and when generally doing conventional the installation with such gear, about 1.14 times of its deceleration multiple.
2, simple in structure, component are less, make easily, do not need special equipment just can make, and volume is little, thereby cost are low, cost performance is high.
Description of drawings
Fig. 1 is the structural representation of the tooth-like plane table thermoconductivity meter of the utility model difference.
Be labeled as among the figure: spragging gear 1, output gear 2, power output semiaxis 3, left lateral star gear 4, right lateral star gear 5; Planet pin 6, braking semiaxis 7, Brake drum 8, drive wheel 9; Braking device 10, equilibrate counterweight 11, gear box casing 12, bearing support 13 and frame 14.
Embodiment
Below through accompanying drawing and embodiment the technological scheme of the utility model is described further.
As shown in Figure 1; The tooth-like plane table thermoconductivity meter of the described difference of the utility model is assembled by spragging gear 1, output gear 2, power output semiaxis 3, left lateral star gear 4, right lateral star gear 5, planet pin 6, braking semiaxis 7, Brake drum 8, drive wheel 9, braking device 10, equilibrate counterweight 11, speed reducer housing 12, bearing support 13 and frame 14.Concrete structure and Placement are:
When braking device 10 is in braking state; Braking semiaxis 7 and spragging gear 1 stop operating; Drive wheel 9, drive left lateral star gear 4, right lateral star gear 5 coiling moving gears 1 and output gear 2 are done the planet running, under the characteristic effect of tooth difference, make power output semiaxis 3 obtain the output of deceleration power.
When braking device 10 was in non-braking state, because of being loaded with load on the power output semiaxis 3, ratio wheel 9, left lateral star gear 4, spragging gear 1 drove braking semiaxis 7 and Brake drum 8 idle running.
Braking semiaxis 7 is installed on the said frame 14 and goes up the spragging gear of installing 1; Be installed in speed reducer housing 12 in planet pin 6 on left lateral star gear 4, right lateral star gear 5, with the power output semiaxis 3 of braking semiaxis 7 coaxial lines and go up the output gear of installing 2 and form the planetary pinion assemblies, velocity ratio require when not too big left lateral star gear 4 design the numbers of teeth with output gear 2, the modulus diameter is identical; Spragging gear 1 is identical with right lateral star gear 5, can reduce the cost of manufacturing like this.When reduction speed ratio is big if desired, two planetary pinions design a little bit smallerly and two planetary numbers of teeth the same, spragging gear 1 specific output gear more than 2 one teeth or few a tooth, the volume of the little retarder in place so widely.When retarder was worked, when spragging gear 1 during greater than output gear 2, turning to of power output semiaxis 3 was identical with drive wheel, and when spragging gear 1 during less than output gear 2, turning to of power output semiaxis 3 is opposite with drive wheel.When doing conventional the installation with same gear, its deceleration multiple is littler about 75 times than the retarder deceleration multiple that the present invention installs.
