Abstract

The utility model discloses a novel hanger of a screw conveyer. The middle part connected with a transmission shaft (5) is sheathed in an axle hole of an I-shaped hanger (6); a deep groove ball bearing (2) is installed between the transmission shaft and the I-shaped hanger; sealing mechanisms are respectively arranged on the walls at the two ends of the axle hole; a lubricating oil channel (8) passes through the wall of the axle hole; the inner end of the lubricating oil channel (8) is communicated with the axle hole; and the outer end thereof is communicated with a lubricating oil filling device. Each sealing mechanism comprises a circular ring shaped sealing protection plate (2), a fluorubber sealing ring (4) and a wearproof check ring (3). The utility model has novel design and reasonable structure, reduces the equipment abrasion to the utmost extent, prolongs the repair cycle of the equipment and lightens the work intensity of repair, thus achieving the aim of greatly improving the production efficiency, saving energy and reducing consumption, and having good economic benefit.

Description

New screw conveyer is hung

One, technical field:

The utility model relates to a kind of conveyor screw to be hung, and particularly relates to a kind of New screw conveyer and hangs.

Two, background technology:

Conveyor screw is hung, form by I-shape flange and plain bearing brasses, I-shape flange two ends are connected with its corresponding screw shaft flange, in the production use, because plain bearing portion do not have sealing arrangement, a large amount of dust enter bearing and with bearing in butter after form greasy filth, not only aggravated the wearing and tearing of bearing, and, can't be lubricated operation to bearing because greasy filth has stopped up lubrication channel at all.Simultaneously, because spare part is scrappy, in maintenance, safeguard in the installation process that the concentricity between the spiral can't obtain the actv. guarantee, make the fault rate height of spiral, cost of overhaul height, maintenance labor content are big, but these are all finalized the design in design and production phase.So, in order to protect I-shape to hang, avoid breakdown of equipment, be forced to often shut down brasses is changed and cleaned in the production, could guarantee the safe operation of equipment.

Three, utility model content:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of modern design, rational in infrastructure, can reduce equipment attrition to greatest extent and prolong equipment overhaul cycle and alleviate service work intensity, hang thereby reach the New screw conveyer that increases substantially production efficiency and energy saving purposes.

The technical solution of the utility model is:

A kind of New screw conveyer is hung, comprise that worker's type hangs (6) and be connected transmission shaft (5), the middle part of described connection transmission shaft (5) is sleeved on described worker's type and hangs in the axis hole of (6), deep groove ball bearing (2) is installed between the two, be respectively arranged with sealing mechanism on the two ends end wall of described axis hole, and the hole wall that radially runs through described axis hole is provided with grease channel (8), and this grease channel (8) is inner to be communicated with described axis hole, and its outer end is communicated with the oil filling device.

Described sealing mechanism contains annular seal backplate (2), viton seal ring (4) and anti-wear back-up ring (3), wherein, the interior annular distance of described annular seal backplate (2) is sleeved on the described connection transmission shaft (5), its end face is fixed on described worker's type by screw (9) and hangs on the axis hole end wall of (6), described viton seal ring (4) is fixed on the described annular seal backplate (2) by anti-wear back-up ring (3), and the inner ring surface of described viton seal ring (4) contacts with the described transmission shaft (5) that is connected.

The end face of described annular seal backplate (2) is provided with annular groove, and described viton seal ring (4) is arranged in the described annular groove.

The beneficial effects of the utility model are:

1, the utility model is hung the needs of operating mode according to spiral, and reasonably spiral is hung and transformed, thus the wearing and tearing minimum that spiral is hung, it is the most stable to work, and production efficiency is the highest.

2, the utility model is owing to solved design, the defect of fabrication of spiral hanging structure, and frequent shutdown overhauls, safeguards the labour intensity that is brought thereby alleviated in the past greatly.

3, the utility model is that the grease lubrication mode of having finalized the design when manufacturing and designing is optimized and transform the good thin oil lubricant of flowing power as, guarantee that to greatest extent the plain bearing faying face has enough lubricating oils, simultaneously, owing to take thin oil lubricant, thin oil can be rinsed the dust in hanging well, has effectively avoided the lasting wearing and tearing of dust to plain bearing.

4, the utility model is under the support of existing machinery technology, realize that easily it can be according to the different operating modes of equipment, science, rationally, independently lubrication interval and lubricated time length are adjusted, it is applied widely, has good economic benefit after the popularization.

Four, description of drawings:

The structural representation that Fig. 1 hangs for New screw conveyer;

The lateral plan that Fig. 2 hangs for New screw conveyer shown in Figure 1.

Five, the specific embodiment:

Embodiment: referring to Fig. 1 and Fig. 2, among the figure, the middle part of the connection transmission shaft 5 that New screw conveyer is hung is sleeved on described worker's type and hangs in 6 the axis hole, deep groove ball bearing 1 is installed between the two, be respectively arranged with sealing mechanism on the two ends end wall of axis hole, and the hole wall that radially runs through axis hole is provided with grease channel 8, and these grease channel 8 the inners are communicated with axis hole, and its outer end is communicated with (not drawing among the figure) with the oil filling device.

Sealing mechanism contains annular seal backplate 2, viton seal ring 4 and anti-wear back-up ring 3, wherein, annular distance is sleeved on and connects on the transmission shaft 5 in the annular seal backplate 2, its end face is fixed on described worker's type by screw 9 and hangs on 6 the axis hole end wall, viton seal ring 4 is fixed on (10 are the bolt of rear end plate of anti-wear back-up ring 3) on the annular seal backplate 2 by anti-wear back-up ring 3, the inner ring surface of viton seal ring 4 contacts with being connected transmission shaft 5, plays the rotary seal effect.Worker's type is hung 6 base crossbeam 7 and is provided with screw 11. is installed

As required, the end face of annular seal backplate 2 is provided with annular groove, and viton seal ring 4 is arranged in the annular groove.

The utility model changes original slip brasses into deep groove ball bearing 1, to change its friction mode, simultaneously sealing mechanism is set in deep groove ball bearing 1 both ends of the surface, good sealing effect, in addition, make spare part become an integral body to a great extent, can't guarantee the concentricity of spiral in the past when having avoided installing because spare part is scrappy, prolonged the service life and the period of inspection and repair of equipment.
