Abstract
The utility model discloses a walking thrust wheel applied to a road surface milling machine of a needle bearing. The walking thrust wheel comprises a wheel axle fixed on a trolley frame through a support base, wherein the support base is fixed on the wheel axle through tightening screws, the needle bearing is sleeved outside the wheel axle, a wheel body is sleeved outside the needle bearing, a bearing end cover for axially loading the needle bearing is arranged on the wheel body through a thread, and a framework oil seal for sealing lubricating grease is arranged in the bearing end cover. According to the walking thrust wheel applied to the road surface milling machine of the needle bearing, the problems of large heating, easy leakage of the lubricating grease and the like of the original thrust wheel are successfully solved, and the working life is prolonged by more than 3 times. Meanwhile, by using the thrust wheel disclosed by the utility model, even if the needle bearing is worn and scrapped, the worn and scrapped needle bearing can be continuously repaired for use after a new bearing is replaced, but the original thrust wheel using a copper sleeve can be only integrally scrapped once being worn and leaking the lubricating grease. By applying the walking thrust wheel, the maintenance frequency can be effectively reduced, and the use cost of the milling machine is greatly lowered.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of pavement milling machine walking thrust wheel of using needle bearing.
Background technology
Pavement milling machine is one of main machine of maintenance of surface operation; The disease such as rut, carbuncle bag, be full of cracks that is used for flexible pavement is carried out maintenance work; Milling rotor through being installed in the milling rotor case carries out milling to decreasing the road surface; And the old material of milling cleared up and reclaim, so that lay new road surface.The running gear of large-scale milling machine generally all adopts the crawler belt mode, and crawler unit is made up of crawler belt, driving wheel, thrust wheel, holder sprocket wheel, guide wheel and track takeup etc.Crawler belt surrounds outside above-mentioned four kinds of wheels, by the tensioning apparatus tensioning, directly contacts with ground.Above-mentioned four kinds of wheels and tensioning apparatus and crawler belt all collect and are contained on the wheel carrier (being bogie frame), thereby form a chassis, and each milling machine has four chassis.Several thrust wheels that are installed on the bogie frame roll on the crawler belt rail level, play a part to transmit vertical load and give crawler belt.Complete vehicle weight is passed to the below crawler belt through bogie frame, thrust wheel, and the below crawler belt is pressed on the ground.The bearing of milling machine thrust wheel employing is sliding bearing (copper sheathing) traditionally; Because the copper sheathing frictional heating is big; In case wearing and tearing cause synthetic lubricant fluid (this type of oil price is very expensive) to leak, thrust wheel will be scrapped in rapid wearing, and its working life was generally 600～800 hours; And can't repair utilization after the wearing and tearing, make thrust wheel become bigger one of consuming cost in the milling machine consumable accessory.
Summary of the invention
The purpose of the utility model provides a kind of pavement milling machine walking thrust wheel of using needle bearing, and it is shorter to have solved existing thrust wheel working life, and is limited in order to prevent thrust wheel heating milling machine free travel distance, the problem that replacement cost is high.
The technical scheme that the utility model adopted is; A kind of pavement milling machine walking thrust wheel of using needle bearing comprises through supporting seat being fixed on the wheel shaft on the bogie frame that supporting seat is fixed on the wheel shaft by holding screw; The wheel shaft outside is with needle bearing; The needle bearing outside is with wheel body, through screw thread the bearing (ball) cover that is used for the axial location needle bearing is installed on the wheel body, and the outside framework oil seal that is used for packing grease is installed in the bearing (ball) cover.
The beneficial effect of the utility model is, through the application of needle bearing thrust wheel, can significantly improve working life to 2500～3000 hour of thrust wheel, increased the permission free travel distance of milling machine, significantly reduces the use cost of equipment.
Description of drawings
Fig. 1 is the structural representation that the utility model is used the pavement milling machine thrust wheel of needle bearing;
Fig. 2 is the vertical view that the utility model is used the pavement milling machine thrust wheel of needle bearing.
Among the figure, 1. holding screw, 2. bearing (ball) cover, 3. wheel body, 4. outside framework oil seal, 5. needle bearing, 6. wheel shaft, 7. supporting seat.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The utility model is used the structure of the pavement milling machine thrust wheel of needle bearing, like Fig. 1 and shown in Figure 2, comprising: holding screw 1, bearing (ball) cover 2, wheel body 3, outside framework oil seal 4, needle bearing 5, wheel shaft 6, supporting seat 7.
The utility model is used the operating principle of the pavement milling machine thrust wheel of needle bearing: wheel shaft 6 is fixed on the bogie frame by supporting seat 7, can not rotate when keeping wheel shaft 6 work.Tare passes to wheel shaft 6 through bogie frame, and wheel shaft 6 is given needle bearing 5 weight transfer again, and needle bearing 5 continues to give wheel body 3 with weight transfer, and wheel body 3 rolls on the crawler belt rail level, and gravity passes to ground through crawler belt the most at last.Supporting seat 7 is fixed on the wheel shaft 6 by holding screw 1, thereby makes 6 one-tenth on supporting seat 7 and wheel shaft as a whole.Bearing (ball) cover 2 is installed on the wheel body 3 through screw thread, is used for the axial location of needle bearing 5.Outside framework oil seal 4 is installed in 2 li of bearing (ball) covers, is used for packing grease.
The utility model is used the pavement milling machine thrust wheel of needle bearing, replaces copper sheathing through using needle bearing, and big, the lubrication oil of heating is prone to problems such as leakage when successfully having solved original thrust wheel work, and working life has improved more than 3 times.Even and the thrust wheel that the uses the utility model bearing continued reparation utilization that under the situation that the needle bearing wearing and tearing are scrapped, can also more renew, and used the leakage of oil of in a single day wearing and tearing of the thrust wheel of copper sheathing integral body to scrap originally.The application of the utility model can effectively reduce the maintenance frequency, reduces the use cost of milling machine significantly.
Claims (1)
1. pavement milling machine walking thrust wheel of using needle bearing; It is characterized in that comprise through supporting seat (7) being fixed on the wheel shaft (6) on the bogie frame, supporting seat (7) is fixed on the wheel shaft (6) by holding screw (1); Wheel shaft (6) outside is with needle bearing (5); Needle bearing (5) outside is with wheel body (3), and wheel body (3) is gone up and through screw thread the bearing (ball) cover (2) that is used for axial location needle bearing (5) is installed, and the outside framework oil seal (4) that is used for packing grease is installed in the bearing (ball) cover (2).
