1, gear, shaft and bearing combination
The two are used for deep groove ball bearing. This combination is used to bear radial load, axial load and small case. When the axial load is larger, should adopt the combination structure of angular contact ball bearing, tapered roller bearing and deep groove ball bearing and thrust bearing. The bearing is oil diluted spin splash using gear, lubrication. Lubricating oil box seat of oil pool, inner gear is splashing rotating off splashing into the box cover, along the inner wall to flow to the box surface groove, through the oil guiding grooves into the bearing. When the speed of immersion gear circumferential V is less than or equal to 2m/s, should use grease lubrication bearing, to avoid possible thin oil wash away grease splashing oil retaining ring, can be used to separate. In order to prevent the loss of lubricant and outside the dust enters in the box, a sealing element is arranged between the bearing end cover and the extended shaft.
Form 3, reducer
1) in order to guarantee the normal work of the reducer, besides the structure design for gear, shaft, bearing combination and box to give enough attention, consideration should also be given to the reasonable selection of reducer lubrication oil tank oiling, oil discharge, check the oil level, processing and assembling and disassembling overhaul box cover and the box seat precise positioning, lifting and other auxiliary parts and components and design. 1) inspection hole mesh condition inspection of transmission parts, and lubricating oil injection into the box, should be set up in the proper position of the box inspection hole. Inspection hole cover on top of the box can be directly observed by gear meshing position. Usually, the inspection hole with cover fixed on the box cover screw.
2) ventilation reducer when in work, the temperature in the box increased, the expansion of gases, pressure increases, in order to make the box expansion air can free discharge, in order to maintain the balance of internal pressure and external pressure does not cause the tank, lubricating oil along the sub box surface or the shaft extension seals and other gap leakage, usually installed at the top of the box breather.
3) bearing cover for the axial position fixing shaft parts and bear the axial load, closed at both ends of the bearing seat hole for bearing cover. Bearing cover flange type and embedded two. Fixed on the box body by six angle bolt extending shaft, bearing cover at is a through hole, which is provided with a sealing device. Advantages of flange type bearing cover is disassembled, convenient adjustment of the bearing and bearing cover, but embedded compared, the number of parts is more, larger size, appearance is irregular.
4) the positioning pin to ensure every removable box cover, still keep the bearing seat hole fabrication processing precision, should be in finishing bearing hole of the front, in the box cover and the box is provided with the positioning connecting flange seat pin. Placed in the box body connecting flange on two longitudinal sides, symmetrical box should be symmetrically arranged, so as to avoid the wrong equipment.
5) oil level indicator check reducer oil pool of oil surface height in the instrument, often keep the oil tanks with the right amount of oil, generally in the box convenient for observation, the oil surface is stable site, installing the oil level indicator.
6) oil drain plug the oil, dirty oil discharge and cleaning agents, should be at the bottom of the box seat, at the lowest position of the oil pool open set oil hole, usually with plug will set oil hole is blocked, oil drain plug and body joint surface should be added between the leak with washer.
