Blower housing, especially for a side channel blower

A side channel blower for a fuel-operated vehicle heater, the side channel blower comprising:

• a blower motor;
• a rotor shaft;
• a delivery wheel;
• and
• a housing arrangement comprising a first housing part with a motor mounting space, the blower motor being arranged in the motor mounting space, and with a rotor shaft mounting, wherein the rotor shaft, rotatable about a shaft axis of rotation, of the blower motor is rotatably mountable at the first housing part rotor shaft mounting;
• a housing cover for sealing the motor mounting space, wherein the housing cover has a cover meshing opening;
• and
• a second housing part with a cover meshing projection, which cover meshing projection is connected in a meshing manner in the cover meshing opening, wherein the cover meshing opening is sealed with the cover meshing projection positioned in a meshing manner in the cover meshing opening, wherein the delivery wheel is carried at an end area of the rotor shaft traversing a bottom area of the first housing part.

A method for the assembly of a side channel blower, the method comprising the steps of:

• providing a blower motor, a rotor shaft, a delivery wheel a first housing part with a motor mounting space and with a rotor shaft mounting, a housing cover for sealing the motor mounting space, wherein the housing cover has a cover meshing opening and a second housing part with a cover meshing projection;
• providing a preassembly assembly unit comprising the first housing part with the blower motor mounted in the motor mounting space and the rotor shaft mounted at the rotor shaft mounting and the housing cover;
• mounting the delivery wheel at the end area of the rotor shaft traversing the bottom area of the first housing part and thereby supporting the other end area of the rotor shaft through the cover meshing opening;
• and
• inserting the second housing part with its cover meshing projection into the cover meshing opening.
