Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments are only not used in restriction scope of the present utility model for the utility model is described.
As depicted in figs. 1 and 2, blower fan retarder of the present utility model and prior art are basic identical, equally also comprise impeller shaft 1, input shaft 2, output shaft 3, upper box 4, support 5 and shoe cream room 6, on upper box 4 and support 5, be equipped with oil guide slot 9, impeller shaft 1 afterbody is connected with cooling oil pump 11, when impeller shaft 1 work, drive cooling oil pump 11 work, on cooling oil pump 11, be provided with Oil Guide supervisor 7, can be when cooling oil pump 11 work, lubricant oil is pumped, Oil Guide supervisor 7 is connected with an interface of a tee union 8 through (support) is rear, the first Oil Guide arm 71 and the second Oil Guide arm 72 on two other interface of tee union 8, have been connected respectively, the first Oil Guide arm 71 is communicated with the oil guide slot of blower fan retarder upper box 4, the second Oil Guide arm 72 is communicated with the oil guide slot of blower fan retarder support 5, the lubricant oil that cooling oil pump 11 is pumped is delivered to the position needing.Meanwhile, the root of input shaft 2 is embedded with the disc 21 that external diameter is 14.8cm, the surrounding of disc 21 have three radiuses be 2cm circular arc type get rid of oily increment groove 211, can increase and get rid of oil mass 50%.
The working principle of this blower fan retarder is as follows: before using, add a certain amount of lubricant oil in shoe cream room 6, when retarder carries out work, impeller shaft 1 rotates, drive cooling oil pump 11 work, lubricant oil is pumped, by Oil Guide, be responsible for 7 and be delivered to the first Oil Guide arm 71 and the second Oil Guide arm 72, then in the oil guide slot 9 flowing on support 5 and upper box 4 by the first Oil Guide arm 71 and the second Oil Guide arm 72, for corresponding site provides lubricated; Simultaneously, disc 21 carries out High Rotation Speed (1500r/min) with input shaft 2, can in large quantities the lubricant oil of blower fan retarder inside be thrown away to the oil guide slot 9 of support 5 and upper box 4 continuously, it is lubricated for input shaft 2 positions being specially input shaft bore both sides and oil guide slot above 9, thereby can guarantee the heat of input shaft 2 to take away and make two bearing lubrication abundant.The lubricant oil of cooling oil pump 11 output can guarantee that input shaft 2 rotating speeds reduce and make getting rid of of disc 21 provide to supplement when oil mass can not meet lubricated needs of bearing, gear to refuel.
