Interior one end is equipped with taper roll bearing 8.Taper roll bearing 8 and deep groove ball bearing 9 are in be fixedly connected with casing 1.Low
During fast gear shaft 6.6 operates, 6.6 two ends of low-speed gear axle can produce larger radial load, therefore circular cone is selected at two ends
Roller bearing 8.And the axial separation that the taper roll bearing 8 at two ends is produced when in use is cancelled out each other, so as to avoid axial direction
Separate and impact is produced on low-speed gear axle 6.6.And the radial load produced by the middle part of low-speed gear axle 6.6 is less, therefore using deep
Ditch ball bearing 9.Deep groove ball bearing 9 is applied to the even extremely high-revolving operation of high rotating speed, and extremely durable, often ties up without the need for Jing
Shield.
In actual production process, in order that transmission is more smoothed out, can be in low-speed gear axle 6.6, input shaft 5 and output shaft
Deca lubricating oil on 7.Undertake in order to production is reduced on the premise of preventing lubricating oil from spilling from casing 1 as far as possible, input shaft 5 leads to
Crossing single sealing of oil sealing 10 and wearing and be connected on 1 side of casing, output shaft 7 is worn by the sealing of double oil seal 11 and casing 1 is connected on back to input shaft 5 one
Side.At the output shaft 7 after one of oil sealing initial failure, another oil sealing also ensures that the interior of the casing 1 of reducing motor 2
Lubricating oil will not be leaked into outside casing 1, so as to improve the sealing of the casing 1, reduce the possibility of 2 oil leak of reducing motor
Property.
Double oil seal 11 includes the first oil sealing 11.1 and the second oil sealing 11.2, and the first oil sealing 11.1 is to output shaft 7 back to input
Distance of the distance of 5 one end end face of axle more than the second oil sealing 11.2 to output shaft 7 back to 5 one end end face of input shaft, the first oil sealing
11.1 is that, without secondary lip oil sealing, the second oil sealing 11.2 is single pair lip oil sealing.The secondary lip of the second oil sealing 11.2 can blocks dust enter cartonning
In body 1, so as to extend the service life of the first oil sealing 11.1.In order to reduce the heat that the second oil sealing 11.2 rubs and produces, the
The thickness of two oil sealings 11.2 is 1/3-the 3/4 of 11.1 thickness of the first oil sealing.In order that the first oil sealing 11.1 has preferably radiating
Property, it is set in distance between the first oil sealing 11.1 and the second oil sealing 11.2.The heat that the friction of first oil sealing, 11.1 lip is produced can
By rejecting heat between the gap between the first oil sealing 11.1 and the second oil sealing 11.2 and the second oil sealing 11.2 and output shaft 7
Outside casing 1, so as to extend the service life of the first oil sealing 11.1.
Installation between first oil sealing 11.1 and the second oil sealing 11.2 for convenience, the external diameter of the second oil sealing 11.2 is more than the
The external diameter of one oil sealing 11.1, the first oil sealing 11.1 and the second oil sealing 11.2 are Split oil seal.When first oil sealing 11.1 is installed
Flat board can be put in the hole for installing the second oil sealing 11.2, then tap flat board, complete the installation of the first oil sealing 11.1.Now
The end face of one oil sealing 11.1 is generally aligned in the same plane with the end face in the hole for installing the second oil sealing 11.2, then installs the second oil sealing 11.2,
Now the first oil sealing 11.1 will not produce impact to the installation of the second oil sealing 11.2, make the second oil sealing 11.2 easier for installation.
Low-speed gear axle 6.6 is installed for convenience, installing hole 12 is provided with 1 body of casing, on installing hole 12, oil is embedded with
Capping 13.
Abat-vent 14 is equipped with upper end cover 1.2 also.In the outdoor of summer or in the case of continuously running, in casing 1
Temperature can become very high, and the gas inside casing 1 can expand, by abat-vent 14 come the inside and outside air of balance box 1
Pressure, so as to not damage the dynamic oil sealing of reducing motor 2, it is ensured that the sealing of the first oil sealing 11.1 and the second oil sealing 11.2 is made
With.
