Abstract
The utility model discloses a chain grate gear box which comprises a plant gear arranged in the box, which is connected with a primary/or second cylindrical gear pair; wherein, the box is divided into a main oil chamber with the primary/ or secondary cylindrical gear pair on the same plane and an auxiliary oil chamber with a plant gear mechanism with little tooth difference; the main oil chamber and the auxiliary oil chamber are communicated by a through oil hole; the axis of the plant gear mechanism with little gear difference is lower than the axis of the primary/or secondary cylindrical gear pair. The chain grate gear box is good for supplementing the lubricating oil of the main oil chamber to the auxiliary oil chamber and improves the gear and bearing lubricating effect and service life; in addition, the plant gear mechanism with little tooth difference reduces the installation position, which not only improves the reliability of operation stability, simplifies the structure design of the box and reduces the manufacturing cost.
Description
Technical field
The utility model relates to a kind of improvement structure of traveling-grate stoker gearbox, can provide lubricant oil to its gear and bearing effectively.
Background technique
Small teeth number difference planet gear transmission type traveling-grate stoker gearbox, as chain fire-gate drive unit is the novel product of the applicant's the eighties exploitation, it mainly is to have adopted the small teeth number difference planet gear speed reducer, is equipped with one-level/or traveling-grate stoker gearbox of forming of secondary cylindrical gear pair.This product is approved by the boiler manufacturing, and is used widely so far, and do not have big modification owing to operate steadily.The upper end that but the weak link of this product maximum is designed planetary gears is installed in gearbox is independently in the grease chamber, because of its structural limitations, lubricant oil has loss in its running, makes annual will replenishing its oiling of carrying out 0.5 kilogram in the application process.And in the practical application, often ignored and refueled or refuel untimely, cause this grease chamber's lubricant oil deficiency, cause small teeth number difference planet gear lubricated insufficient, the aggravation of wheel odontotripsis appears, relevant bearing running hot and influence problem such as working life.
Summary of the invention
Situation in view of above-mentioned prior art; the utility model provides a kind of improvement structure of traveling-grate stoker gearbox; it has can overcome the partly lubricated inadequate defective of small teeth number difference planet gear mechanism driving, thereby reaches the purpose of lubricating, take into account the working life of improving gear and bearing of protection planetary gears.
For achieving the above object, technical solution of the present utility model is, a kind of traveling-grate stoker gearbox comprises the small teeth number difference planet gear mechanism that is provided with in the casing, with one-level/or the secondary cylindrical gear pair be connected; Wherein in described casing, be partitioned into and have conplane one-level/or the main grease chamber of secondary cylindrical gear pair and the secondary grease chamber of small teeth number difference planet gear mechanism; And by an oil through two grease chambeies are connected between main grease chamber and the secondary grease chamber; The axis of described small teeth number difference planet gear mechanism is lower than one-level/or the axis of secondary cylindrical gear pair.Therefore, the axis that has designed small teeth number difference planet gear mechanism is positioned at one-level/or the axis of secondary cylindrical gear pair, helps small teeth number difference planet gear mechanism like this and obtains lubricated fully; In addition, also, can replenish the lubricant oil in the secondary grease chamber fully, effectively guarantee the working life of small teeth number difference planet gear mechanism and bearing because two grease chambeies are interconnected at grade.
According to scheme of the present utility model, the axis of related small teeth number difference planet gear mechanism and one-level/or the axis spacing of secondary cylindrical gear pair be the 30-50 millimeter.Help like this keeping at grade, obtain the lubricant oil that replenishes mutually with main grease chamber; Because of having reduced small teeth number difference planet gear mechanism, saved the grease chamber that adds of outside independent configuration simultaneously.
In a word, traveling-grate stoker gearbox of the present utility model, because of with one-level/or the secondary cylindrical gear pair with in small teeth number difference planet gear mechanism is installed in different major and minor grease chamber, same plane, not only can effectively be lubricated, and two grease chambeies are communicated with each other, the lubricant oil that helps main grease chamber replenishes secondary grease chamber, has improved gear and bearing lubrication effect and working life; In addition, mechanism has reduced the mounting point because of small teeth number difference planet gear, has not only improved the reliability that operates steadily, and has also simplified the structural design of casing, has reduced manufacture cost.
Description of drawings
Fig. 1 is a topology view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model will be further described.The accompanying drawing of giving only is to be used for reference and explanation usefulness, is not to be used to limit the utility model scope.
By Fig. 1, shown in, the traveling-grate stoker gearbox, it has a casing 6, is partitioned into the main grease chamber 5 of secondary cylindrical gear pair (among the figure mark) and the secondary grease chamber 2 of small teeth number difference planet gear mechanism 1 by the isolating frame 3 that is provided with on the bottom plane in it; Be replenishing of the lubricant oil that guarantees secondary grease chamber 2, and on isolating frame 3, have oil through 4 because two grease chambeies are at grade, make two grease chambeies each other connected sum replenish mutually, keep good lubricating effect.Based on satisfying above-mentioned design feature, therefore, should be lower than the axis of secondary cylindrical gear pair to the axis of described small teeth number difference planet gear mechanism 1; Spacing between the two axial lines is the 30-50 millimeter.
In the foregoing description, be the driving mechanism of the secondary cylindrical gear pair selected for use, be suitable for the driving mechanism of primary cylinder gear pair equally.
During working state, motor power is delivered to eccentric shaft by large and small belt pulley and goes up the small teeth number difference planet gear mechanism rotation of installing, and by fixed gear ring, output gear deceleration, give intermediate gear shaft with transmission of power, slow down through the secondary cylindrical gear pair again power is exported by output shaft.Structure member in above-mentioned is original technology.And the mounting point that is partitioned into two major and minor grease chambeies that are interconnected and reduction small teeth number difference planet gear mechanism on the same plane in casing is to implement key of the present utility model.
Claims (2)
1, a kind of traveling-grate stoker gearbox comprises the small teeth number difference planet gear machine that is provided with in the casing, with one-level/or the secondary cylindrical gear pair be connected; It is characterized in that in described casing (6), being partitioned into and have conplane one-level/or the main grease chamber (5) of secondary cylindrical gear pair and the secondary grease chamber (2) of small teeth number difference planet gear mechanism (1); And by an oil through (4) two grease chambeies are connected between main grease chamber (5) and secondary grease chamber (2); The axis of described small teeth number difference planet gear mechanism (1) is lower than one-level/or the axis of secondary cylindrical gear pair.
2, traveling-grate stoker gearbox according to claim 1, it is characterized in that the axis of described small teeth number difference planet gear mechanism (1) and one-level/or the axis spacing of secondary cylindrical gear pair be the 30-50 millimeter.
