Description

A kind of retarder

Technical field

The utility model relates to a kind of speed reducer, specifically a kind of a kind of retarder that adopts worm gear, worm screw to come speed change.

Background technique

Relevant by retrieval patent documentation does not retrieve identical retarder with the utility model structure at present as yet.The kind of existing retarder is more, differs from one another.Worm gear, worm reducer are because reduction speed ratio is big, and factors such as compact structure are widely used in the bigger occasion of reduction speed ratio by people.Because worm gear, worm screw rotating speed of worm gear in moderating process is lower, the worm screw rotating speed is bigger, thereby retarder is generated heat easily, produce wearing and tearing, need clear up after when using one section, remove the abrasive particle that produces retarder.Though existing double worm and gear retarder has certain progress on compact structure, but also because the problem of its structure, heating value is increased, the two worm gears of two-stage, worm reducer combine in addition, the wearing and tearing of worm gear, its granulometric impurity has aggravated the wearing and tearing of retarder, thereby has influenced the life-span of retarder, so be necessary existing worm gear, worm reducer are improved, to better meet actual needs.

Summary of the invention

The purpose of this utility model is that a kind of improvement on existing two worm gears, worm reducer will be provided, and has radiating block, and it is little to wear and tear, and rational in infrastructure, can be applicable to the retarder of outdoor operation.

Technical characteristics of the present utility model is: be designed to be made up of worm shaft I, worm gear I, sealing cover, housing, worm shaft II, worm gear II, worm-wheel shaft, oiling device, oil ga(u)ge, fuel outlet valve on the basis of considering cleaning convenience, good sealing effect, rapid heat dissipation; In the inner chamber of housing, be provided with worm shaft I, worm gear I, worm shaft I is meshed with worm gear I, worm gear I is arranged on the worm shaft II, described worm shaft II is meshed with worm gear II, worm shaft II, worm gear II are arranged in the inner chamber of housing, and worm gear II is connected with worm-wheel shaft, and are bearing on the housing by worm-wheel shaft, on housing, also be provided with sealing cover, on housing, also be provided with oiling device; Described oil ga(u)ge is provided with on the side of housing, is provided with fuel outlet valve in the lower end of housing.

Described worm shaft I is provided with and spatters food tray I, and described its input end of worm shaft I can be interior connection, the outer structural type that connects.

Described sealing cover is provided with gripping mechanism.

Described housing is provided with radiating fin I on the position outer wall that worm shaft I is installed, be provided with radiating fin II on the outer wall of worm gear II.

Described worm shaft II is provided with and spatters food tray II.

Described worm-wheel shaft can for output shaft in be connected, the outer structural type that connects.

During assembling, worm shaft I is meshed with worm gear I, and worm shaft I is carried out end face seal by seal ring.The sealing cover that is provided with on worm shaft II, housing its objective is in order to prevent that rainwater from entering retarder setting.The worm and wheel II of worm shaft II is meshed.Worm shaft I, worm shaft II go up to be provided with and to spatter food tray and its objective is for the oil back of splashing worm screw, worm gear heat radiation, cleaning impurity are provided with.The radiating fin I that is provided with on housing, radiating fin II its objective is that the heat in order to produce in the casing that leaves in time is provided with.The lubricant oil that adds in the housing also shows by oil ga(u)ge, and the lubricant oil of having used in housing by fuel outlet valve after operation a period of time is put and removed, and refills lubricant oil by oiling device and reuse.

The utility model has the advantages that: owing to spatter food tray and match being provided with on the worm shaft, thereby reached the purpose of timely heat radiation, cleaning impurity, reduced the wearing and tearing of worm gear, worm screw, reduced temperature with radiating fin on the housing; Owing to be provided with sealing cover, thereby avoided rainwater to infiltrate in the housing, reduce damage, thereby make the utility model can apply to outside work to parts; Because housing is provided with radiating fin, thereby heat is in time distributed; Owing to connect in worm-wheel shaft is designed to or the outer structural type that connects, thereby the using scope of retarder is wide; Since compact structure, good heat dissipation effect, and long service life is so there is very big practical and popularizing value.
