Cold stamping one-time forming bearing housing

Abstract

The invention discloses a cold stamping one-time forming bearing chamber bearing seat and a production method thereof, which comprises a bearing seat upper seat 1, a base 2, a bearing chamber 4, a sealing cover 3, fixing bolts, etc., and the edge 13 of the sealing cover is high on both sides and low in the middle. structure, so that the sealing cover 3 is tightly buckled and pressed in the original bearing chamber 4, and it is not easy to fall off. The bearing chamber 4 is tightly installed in the bearing seat cavity 11 surrounded by the bearing seat upper seat 1 and the base 2, and the bearing is installed in the center of the bearing chamber 4 and the sealing cover 3; the bearing seat upper seat 1 and the base 2 are provided with bolt holes; It can be fixed with the corresponding mechanical bolt holes. Because the bearing seat is produced by cold stamping technology, the bearing seat has a large pressure bearing capacity. It not only has the precision and firmness of the cast bearing seat, but also has a simple process and high toughness, which is not easy to break. It also plays a dust-proof role and prolongs the service life of the bearing. .

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a cold stamping one-time forming bearing chamber bearing seat. Background technique [0002] Bearing seats are widely used in the mechanical field. At present, most of them are casting bearing seats. The production process of casting bearing seats is very complicated. Cost. Cast bearing housings are brittle and easy to break, bulky and inflexible to use. Coalized iron is generally used for casting, and the dust, harmful gas and noise generated during the production process have caused environmental pollution and human health hazards. The existing stamping bearing seat only simplifies the production process; reduces the cost, but loses the most basic firmness and precision of the bearing seat, reduces the service life of the bearing and the bearing seat, and can only be used in slow speed, high precision The utilization rate is low in small basic machines with low ...

Problems solved by technology

[0002] Bearing seats are widely used in the mechanical field. At present, most of them are casting bearing seats. The production process of casting bearing seats is very complicated. Cost. The cast bearing seat is brittle and easy to break, bulky and inflexible to use

Coalized iron is generally used for casting, and the dust, harmful gas and noise generated during the production process have caused environmental pollution and human health hazards.

The existing stamping bearing seat only simplifies the production process; reduces the cost, but loses the most basic firmness and precision of the bearing seat, reduces the service life of the bearing and the bearing seat, and can only be used in slow speed, high precision Low utilization rate in small basic machines with low load and light load

Moreover, the combination of the traditional bearing seat and the sealing ring needs to be fixed with bolts after drilling and tapping, which is very troublesome.
