The surface roughness of 0.05mm, the external mating surface of eccentric bushing 5 and the matching hole mating surface of babinet 4 is not less than Ra3.2.
The speed regulating method of the coalcutter transmission system speed adjusting gear of the embodiment of the present invention is introduced in detail below.
Fig. 3 is the flow chart of coalcutter transmission system speed adjusting gear speed regulating method shown in FIG. 1.As shown in figure 3, above-mentioned reality
The speed regulating method for applying the coalcutter transmission system speed adjusting gear of example includes the following steps：
Eccentric bushing 5 is overturn 180 ° by step S11, changes fixed position relative of the eccentric bushing 5 on babinet 4；
Step S12 replaces supports end cap 6, make in supports end cap 6 for install the mounting shaft hole of intermediate gear shaft 2 with partially
The mounting hole of heart set 5 keeps face；
Step S13 adjusts the tooth of the first driving gearshaft 1 and the second driving gearshaft 3 according to the eccentricity of eccentric bushing 5
Tooth number replaces the first driving gearshaft 1 and the second driving gearshaft 3, keeps the first driving gearshaft 1,2 and of intermediate gear shaft
Second driving gearshaft 3 is intermeshed.
Wherein, the incrementss or decrement of the number of gear teeth of the first driving gearshaft 1 and the second driving gearshaft 3 are equal to inclined
The heart covers the ratio of 5 eccentricity and module.Specifically, when the number of teeth of the first driving gearshaft increases, the second transmission gear
The number of teeth of axis is reduced；When the number of teeth of the first driving gearshaft is reduced, the number of teeth of the second driving gearshaft increases.
As described above, the coalcutter transmission system speed adjusting gear of the present invention in intermediate gear shaft 2 by adding setting-up eccentricity
5 are covered, while setting the eccentricity of eccentric bushing 5 to the integral multiple of module, such as sets the eccentricity of eccentric bushing 5 to
Im, wherein i are integer, and m is module.When transmission system speed adjusting gear needs speed governing, eccentric bushing 5 is overturn 180 °, this
When, fixed position relative of the eccentric bushing 5 on babinet 4 changes, i.e., the intermediate gear shaft 2 being connect with eccentric bushing 5 is on babinet 4
Relative position changes, and knots modification is equal to the eccentricity im of eccentric bushing 5；It is passed at this point, replacing the first driving gearshaft 1, second
Movable gear shaft 3 makes the number of gear teeth of the first driving gearshaft 1 decrease or increase i, the number of gear teeth of the second driving gearshaft 3 increases
Add deduct few i, and then the first driving gearshaft 1, intermediate gear shaft 2 and the second driving gearshaft 3 is enable to be intermeshed；Together
When, supports end cap 6 is replaced, supports end cap 6 and the first driving gearshaft 1, intermediate gear shaft 2, the second driving gearshaft 3 is made to coordinate
Connection.Since the number of gear teeth of the first driving gearshaft 1 and the second driving gearshaft 3 changes, and then makes transmission system
It exports rotating speed to change, realizes speed-regulating function.
As depicted in figs. 1 and 2, before and after speed adjusting gear speed governing, fixed position relative of the eccentric bushing 5 on babinet 4 is different,
The position of mounting hole of eccentric bushing 5 changes, and knots modification is determined by the eccentricity of eccentric bushing 5.Specifically, eccentric bushing 5 is inclined
Heart amount can require to be configured according to the transmission system speed governing needed for real work.
Similarly, when transmission system is the spinning transmission of three axis or more, eccentric bushing 5 can be set as according to actual conditions
More than one, to realize the speed governing requirement of the spinning transmission system of three axis or more.
Further, the first driving gearshaft 1, intermediate gear shaft 2 and the second driving gearshaft 3 can be profile modified gear or
X-zero gear, it is preferable that in order to facilitate the processing and manufacturing and installation of gear shaft, the first driving gearshaft 1, intermediate gear shaft 2
It is X-zero gear with the second driving gearshaft 3.
The coalcutter transmission system speed adjusting gear and method of the present invention can be in the feelings for not changing machine driven system babinet
Under condition, realize that the rotating speed of three axis or multi-axle drive mechanism is adjustable, ensure that the versatility of equipment middle case class part, interchangeability and
Economy.
Coalcutter transmission system speed adjusting gear provided by the invention and method by covering 5 in 2 setting-up eccentricity of intermediate gear shaft,
And set the eccentricity of eccentric bushing 5 to the integral multiple of the module of governor gear, when transmission system needs speed governing, only need
Eccentric bushing 5 is overturn 180 °, while correspondingly replacing the first driving gearshaft 1, the second driving gearshaft 3 and supports end cap 6,
The speed-regulating function that can realize transmission system to meet applying working condition requirement, while can ensure to be used for setting-up eccentricity on babinet 4
Cooperation pore size and the position for covering the 5, first driving gearshaft 1, the second driving gearshaft 3 and supports end cap 6 are constant, it is ensured that babinet
4 can exchange completely before and after speed governing, have versatility, interchangeability and economy.
