CN201747655U - Novel bearing seat for anti-kickback device - Google Patents

Abstract

The utility model relates to a novel bearing seat for an anti-kickback device, which comprises a bearing seat. The utility model is characterized in that a skeleton oil seal slot is arranged at the bottom of the bearing seat; an opening of the skeleton oil seal slot is arranged at the bottom of the bearing seat; a steel plate is arranged on the bottom of the bearing seat; and a shaft hole on the steel plate is coaxial with the skeleton oil seal slot. The utility model has the advantage of that a skeleton oil seal can be assembled and disassembled from the lower side, and parts above the skeleton oil seal do not need to be completely disassembled, so the utility model provides convenience for maintenance.

Description

A kind of novel bearing seat that is used for anti-reverse mechanism

Technical field

The utility model relates to a kind of bearing block structure that is used for anti-reverse mechanism, particularly a kind of improvement that is used for the bearing block structure of anti-reverse mechanism.

Background technique

Vertical sewage pump is easy to form counter-rotating when starting, so the counter-rotating will prevent starting mode of pump with anti-reverse mechanism the time.Bearing support is a component part of anti-reverse mechanism.Bearing is contained in the bearing support, pushes down the outer ring of bearing with the counnter attack rotating disk, pushes down the inner ring of bearing with axle sleeve.Bearing support below is equipped with outside framework oil seal and is used for sealed bearing, prevents that the lubricating grease in the bearing support from leaking.Because bearing support and outside framework oil seal are fixed, and axle rotates, so can rub between outside framework oil seal and the axle, will damage after outside framework oil seal surpasses working life, at this moment needs the outside framework oil seal that more renews.The (see figure 1) outside framework oil seal is contained in 10 li of the outside framework oil seal grooves of bearing support inside in original structure, the outside framework oil seal of dismantling at first will all be dismantled the bearing more than the outside framework oil seal and other part, change very trouble, and may cause bearing wear, even the damage of some part.

Summary of the invention

The purpose of this utility model is existing the problems referred to above in inside that the outside framework oil seal of the bearing support of anti-reverse mechanism in the solution prior art is contained in bearing support, and a kind of novel improved bearing support is provided.A kind of novel bearing seat that is used for anti-reverse mechanism of the utility model design, comprise bearing support, it is characterized in that: offer the outside framework oil seal groove in the bottom of bearing support, the outside framework oil seal channel opening is positioned at the bottom surface of bearing support, on the bearing support bottom surface steel plate is installed, the axis hole on the steel plate is coaxial with the outside framework oil seal groove.The utility model has the advantages that and need not the part more than the outside framework oil seal is all dismantled from fit beneath and dismounting outside framework oil seal, provide convenience to maintenance.

Description of drawings

Below in conjunction with accompanying drawing and example the utility model is elaborated.

Accompanying drawing 1 is the prior art constructions schematic representation;

Accompanying drawing 2 is a structural representation of the present utility model.

Embodiment

Comprise bearing support 1 among the figure, it is characterized in that: offer outside framework oil seal groove 2 in the bottom of bearing support 1, the outside framework oil seal channel opening is positioned at the bottom surface of bearing support, and steel plate 3 is installed on the bearing support bottom surface, and the axis hole 4 on the steel plate is coaxial with the outside framework oil seal groove.

Outside framework oil seal channel opening on the bearing support down like this can be from fit beneath and dismounting outside framework oil seal.When changing outside framework oil seal, do not need the above part of outside framework oil seal all to dismantle, provide convenience to maintenance.Simultaneously, because this pump is a vertical-type axial-flow pump, outside framework oil seal be subjected to gravity effect and working time of a specified duration (but also not reaching working life) can wear and tear, in order to prevent that outside framework oil seal comes off in the pump operation process, below outside framework oil seal, adorn a block plate (casting thickness of support frame oil sealing is suitable in steel plate thickness and the original structure).Like this, when changing outside framework oil seal, only this steel plate need be dismantled gets final product.

Claims (1)

1. novel bearing seat that is used for anti-reverse mechanism, comprise bearing support, it is characterized in that: offer the outside framework oil seal groove in the bottom of bearing support, the outside framework oil seal channel opening is positioned at the bottom surface of bearing support, on the bearing support bottom surface steel plate is installed, the axis hole on the steel plate is coaxial with the outside framework oil seal groove.
