Abstract
The utility model discloses a bearing pedestal for a roller bearing of a conveyer, comprising a bearing pedestal body, a bearing located in the bearing pedestal body, a sealing member and a check ring, wherein the sealing member is located above the bearing; the check ring is located above the sealing member; the check ring is connected with the bearing pedestal body; and the upper surface of the check ring and the upper surface of the bearing pedestal body are in a same plane. The bearing pedestal has the advantages of being small in part quantity and low in production cost; the bearing pedestal body, the bearing and the sealing member are assembled into a whole by using the check ring via one-time precision stamping, thereby ensuring convenient mounting, improving the production efficiency and the assembling quality and greatly lightening the overall weight of a roller; and the joint between the check ring and the bearing pedestal body is completed enclosed, thereby ensuring that dust, water and other impurities can not enter the inner cavity of the bearing pedestal and prolonging the service life.
Description
Technical field
The utility model relates to a kind of accessory of belt conveyer carrying roller, particularly discloses a kind of conveyer carrying roller bearing bearing seat.
Background technology
Carrying roller is the important component part of belt conveyer convey materials, and the quality of carrying roller directly influences normal operation, service life and the energy consumption of belt conveyer complete machine.Bearing seat is the major part that is used to support parts such as carrying roller internal bearings, and it is widely used in open-air dust is big, corrosive property the is high environment, and all carry places as mine, building stones factory, cement mill and coke-oven plant, washery, fertilizer plant, harbour etc.Therefore bearing seat also is one of vitals that constitutes belt idler.The height of its precision also will directly have influence on the carrying roller quality, have influence on the safe and stable operation of conveyer then.
How Idler bearing pedestal body in the belt conveyer is manufactured in the mode of foundry goods in the tradition.At first this bearing seat is owing to be subjected to the restriction of production tooling and technology level; make the blank quality instability of bearing seat; foundry defects such as inner some pore of foundry goods, sand holes, crackle expose not thoroughly after the prtreatment, have processing often and thoroughly do not cause and reprocess.Repair welding still has the existence of above-mentioned defective behind the fine limit work, in case will influence the accuracy of form and position of the intact endoporus of fine limit work.Especially the defect processing of endoporus easily produces distortion after will producing bigger influence and bearing seat fine limit work to the precision of endoporus.
Secondly foundry goods bearing seat processing technology complexity and deadweight are big, reject rate is high, install extremely inconvenient; And working under wet environment very easily is corroded, and shorten service life.All be difficult to satisfy the requirement of economic development at aspects such as output, quality, performance and economic benefits.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art, provide a kind of easy for installation, quality good, long service life, conveyer carrying roller bearing bearing seat that productive costs is low.
The utility model is achieved in that a kind of conveyer carrying roller bearing bearing seat, comprise bearing seat, be positioned at the bearing of bearing seat, it is characterized in that: also comprise sealing member, back-up ring, described sealing member is positioned at the top of bearing, described back-up ring is positioned at the sealing member top, described back-up ring links to each other with bearing seat, and the upper surface of the upper surface of back-up ring and bearing seat is in same plane.
Described back-up ring links to each other with bearing seat by nested mode, and the inwall that is specially bearing seat is provided with groove, and the outside circle of described back-up ring is provided with boss, and described boss embeds in the groove.
Described sealing member is the labyrinth seal circle.
The beneficial effects of the utility model are: the utility model number of parts is few, reduces production costs; Adopt precision stamping of back-up ring that bearing seat, bearing and sealing member are assembled into an integral body, make the carrying roller product by 9 original covers, be modified into 3 covers, not only be convenient to install and also improved production efficiency and assembly quality, and alleviated the overall weight of carrying roller greatly; Back-up ring and bearing seat joining place complete closed guarantee that dust, water and other impurity can not enter the bearing seat inner chamber, and increase service life.
