Description
Technical field
The utility model relates to HL loop chain type, NE plate link chain type hoist, especially relates to a kind of caterpillar elevater bottom tension wheel.
Background technology
The revolving structure (comprising bearing) of chain type (comprising HL loop chain type and NE plate chain type) gig bottom tension wheel is all on external adjustment plate outside housing, the tensioning of chain is maintained by external force, ensure that gig chain can stable operation and can not clash into housing with this, meet accident.But in the course of the work, because sprocket shaft rotates, sealing herein is very easily damaged, when gathering dust bad at lifting powder especially, often outwards dusting in this place, causes bearing damage, adds frequency of maintenance and maintenance cost, reduce work efficiency.
Summary of the invention
The purpose of this utility model is the caterpillar elevater bottom tension wheel providing a kind of good sealing effect, work efficiency high.
For achieving the above object, the utility model can take following technical proposals:
Caterpillar elevater bottom described in the utility model tension wheel, comprise the sprocket shaft with turning gear and the sprocket wheel that is arranged on described sprocket shaft, described turning gear is arranged in the middle part of described sprocket shaft, and described sprocket wheel is arranged on the outside of described turning gear by butt flange;
Described turning gear comprises the sealed chamber that symmetry is sleeved on a pair swing bearing on sprocket shaft and is coated on outside described swing bearing, and the two ends of described sealed chamber are respectively arranged with end cover, are provided with poted assemblies between described end cover and sprocket shaft; In described sealed chamber, be injected with lubricating oil and be filled with pressure gas.
Described poted assemblies is the T-shaped sealing shroud be sleeved on described sprocket shaft, the T-shaped sealing shroud rear portion of described end cover is provided with O-ring seals, the inner side of described O-ring seals is provided with briquetting, between described T-shaped sealing shroud front portion and described briquetting, is provided with pressure spring.
Central axis along described sprocket shaft offers gaging hole, and described gaging hole is connected with described sealed chamber inside by longitudinal holes, and described gaging hole is provided with compression indicator.
On the drain oil offered bottom described sealed chamber, sealing is provided with oily stifled.
The utility model has the advantage of compact conformation, reasonable in design, sealing and dustproof effect is stronger, keeps in repair easier.In the middle part of sprocket shaft turning gear external for tradition being moved to casing internal, easily well seal up the housing of gig feed end; Sprocket wheel is arranged on the outside of turning gear by butt flange, different sprocket wheels can be installed to adapt to different gigs by flange, and more can change the part of wearing and tearing by fast speed; In sealed chamber, inject lubricating oil lubricate bearing, cooling performance is better; Be filled with pressure gas in sealed chamber, enhance dust-proof effect, the sealing effectiveness of poted assemblies can also be reacted by compression indicator intuitively; The combined action of pressure spring and briquetting can make O-ring seals tightly be attached on end cover, and sealing effectiveness is better, keeps in repair also convenient simultaneously.
Tension wheel of the present utility model only needs current check, maintaining certain pressure just can the work of continous-stable, check during by changing oil that oil can judge the wear pattern of bearing, without the need to dissembling inspection, very convenient, if coordinate the lower sprocket of wear-resistant material, can continuous working more than 5 years without change part.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, caterpillar elevater bottom described in the utility model tension wheel, comprise the sprocket shaft 1 with turning gear and the sprocket wheel 2 that is arranged on sprocket shaft 1, for improving its dust-proof effect, be convenient to maintenance, this turning gear is arranged in the middle part of sprocket shaft 1, and sprocket wheel 2 is arranged on the outside of turning gear by butt flange 3, and the gig that can adapt to different model uses (being convenient for changing sprocket wheel 2);
This turning gear comprises the sealed chamber 5 that symmetry is sleeved on a pair swing bearing 4 on sprocket shaft 1 and is coated on outside swing bearing, and the two ends of sealed chamber are respectively arranged with end cover 6, are provided with poted assemblies between end cover 6 and sprocket shaft 1; In sealed chamber 5, be injected with lubricating oil and be filled with pressure gas.
The utility model sealing means used is mechanical seal mode: sealing assembly comprises the T-shaped sealing shroud 7 be sleeved on sprocket shaft, the T-shaped sealing shroud rear portion of end cover 6 is provided with O-ring seals 8, the inner side of O-ring seals 8 is provided with briquetting 9, between T-shaped sealing shroud front portion and briquetting, is provided with pressure spring 10.During work, pressure spring 10 promote briquetting 9 by O-ring seals 8 tightly be attached on end cover 6, can keep the sealing that axle head is stable, dust-proof effect is better.
Central axis along sprocket shaft 1 offers gaging hole 11, and gaging hole 11 is connected with sealed chamber 5 inside by longitudinal holes 12, and gaging hole is provided with compression indicator 13.Like this, the sealing situation of sealed chamber inside can be reacted intuitively without the need to dismounting, convenient.
On the drain oil offered bottom sealed chamber 5, sealing is provided with oil stifled 14, can be changed the lubricating oil in sealed chamber 5 by drain oil in time, checks that oil can judge the wear pattern of bearing when changing oil, very convenient.
