Abstract
The utility model discloses a speed reducer. The speed reducer comprises a reduction gearbox body, an input shaft, a middle transmission shaft and an output shaft, wherein the gear A of the input shaft is engaged with the gear B of the middle transmission shaft; the gear C of the middle transmission shaft is engaged with the gear D of the output shaft; the input shaft, the middle transmission shaft and the output shaft are vertically arranged in parallel; the two ends of each of the input shaft, the middle transmission shaft and the output shaft are supported on the reduction gearbox body by a bearing revolving support; the input end of the input shaft extends out of the reduction gearbox body from the bottom of the reduction gearbox body. The speed reducer is characterized by adopting forced oil-jetting lubrication, wherein oil-jetting points are arranged on the engaged part of the gear A and the gear B, the engaged part of the gear C and the gear D, the upper support bearing part of the input shaft, the upper support bearing part of the middle transmission shaft and the upper support bearing part of the output shaft respectively. The speed reducer is mainly applied to industries of wire drawing, electric power and the like, and has the advantages of being high in transmission efficiency, and small in working temperature rise and effectively preventing oil leakage.
Description
Technical field
The utility model relates to a kind of improvement invention of speed reducer.
Background technique
In wire drawing, the industries such as electric power, the flange that many times is applied to parallel axes series is upwards installed the speed reducer of pattern, the main feature of above-mentioned speed reducer is: input shaft, intermediate propeller shaft is parallel vertical setting with output shaft, the mounting flange that the top construction opening of output shaft makes progress, it adopts flooding system lubrication, because input shaft, the upper bearing (metal) of intermediate propeller shaft and output shaft is bearing in the top of deceleration box, for guaranteeing to lubricate, to fill it up with lubricant oil in the deceleration box of speed reducer during work, churning loss was large when this just caused speed reducer work, transmission efficiency is low, the temperature rise of should not dispelling the heat, the adverse consequencess such as easy leakage of oil.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model aims to provide that a kind of transmission efficiency is high, the speed reducer of little, the oil-leakage-prevention of work temperature rise.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
A kind of speed reducer, comprise deceleration box, input shaft, intermediate propeller shaft and output shaft, the gear B engagement that the gear A that input shaft is provided with and intermediate propeller shaft are provided with, the gear D engagement that the gear C that intermediate propeller shaft is provided with and output shaft are provided with, input shaft, intermediate propeller shaft and output shaft vertically be arranged in parallel, input shaft, the bearing pivoting support is passed through on deceleration box in the two ends of intermediate propeller shaft and output shaft, the input end of input shaft is from the protruding deceleration box in the bottom of deceleration box, it is characterized in that: described speed reducer adopts forces oil jet lubrication, gear A and gear B engagement position, gear C and gear D engagement position, the upper support bearing portion of input shaft, the upper support bearing portion of intermediate propeller shaft and the upper support bearing portion of output shaft are respectively equipped with the oil spout point.
Speed reducer of the present utility model, change traditional flooding system lubrication for forcing oil jet lubrication, churning loss when speed reducer is worked like this is just very little, transmission efficiency improves greatly, and lubricant oil is beneficial to heat radiation, effectively reduces the work temperature rise of speed reducer, simultaneously, do not have a large amount of lubricant oil to pile up in the deceleration box, can effectively prevent leakage of oil.
The overhanging deceleration box of described input shaft input end position is provided with two seals, and two seals arranges in the both sides of the lower support bearing of input shaft, and the lower support bearing of input shaft adopts grease lubrication.Because whole speed reducer only has the input end of input shaft from the protruding deceleration box in the bottom of deceleration box, so after adopting two seals, can effectively cut off leaking outside of lubricant oil, the utility model oil-leakage-prevention is effective.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by specific embodiment the utility model is described in detail and illustrates:
As shown in the figure, speed reducer of the present utility model, comprise deceleration box 1, input shaft 2, intermediate propeller shaft 3 and output shaft 4, the gear B engagement that the gear A that input shaft 2 is provided with and intermediate propeller shaft 3 are provided with, the gear D engagement that the gear C that intermediate propeller shaft 3 is provided with and output shaft 4 are provided with, input shaft 2, intermediate propeller shaft 3 and output shaft 4 vertically be arranged in parallel, input shaft, the bearing pivoting support is passed through on deceleration box 1 in the two ends of intermediate propeller shaft and output shaft, the input end of input shaft 2 is from the protruding deceleration box in the bottom of deceleration box 1, the bottom side of deceleration box 1 is provided with oil outlet 5, described speed reducer adopts forces oil jet lubrication, gear A and gear B engagement position are provided with oil spout point 11, gear C and gear D engagement position are provided with oil spout point 15, the upper support bearing portion of input shaft 2 is provided with oil spout point 12, the upper support bearing portion of intermediate propeller shaft 3 is provided with oil spout point 13, the upper support bearing portion of output shaft 4 is provided with oil spout point 14, the lubricant oil of each oil spout point is installed in the outer oil dispenser fuel feeding of deceleration box by oil pump by one, the overhanging deceleration box of described input shaft 2 input ends position is provided with two seals, sealing 6 and sealing 8, two seals arranges in the both sides of the lower support bearing 7 of input shaft, and the lower support bearing 7 of input shaft adopts grease lubrication.
Speed reducer of the present utility model, owing to having adopted the pressure oil jet lubrication, so the churning loss during speed reducer work is just very little, transmission efficiency improves greatly, and lubricant oil is beneficial to heat radiation, effectively reduce the work temperature rise of speed reducer, simultaneously, there is not a large amount of lubricant oil to pile up in the deceleration box, more because the input end of input shaft is provided with two seals, so can effectively cut off leaking outside of lubricant oil, oil-leakage-prevention is effective.
