Abstract

PURPOSE:To prevent a stator for a compressor from turning over or warpage by providing a recess around a bolt hole formed at a frame and clamping with a bolt so that a contacting part except a seat formed on the stator is intruded into the recess. CONSTITUTION:A rotor 9 is rotatably supported to a frame 1 as a component of a compressor body, and a stator core 7 of a stator 5 disposed outside is clamped at the peripheral edge by a bolt 6 to a supporting leg 4 of the frame 1. A recess 11 is formed to surround a bolt hole 10 of the frame at this time, a seat 12 is formed at the part except the part corresponding to the recess 11 on the contacting surface of the core 7 so that, when clamped by the bolt 6, the contacting part 7a except the seat 12 is intruded into the recess 11. Accordingly, sufficiently clamping strength can be obtained, thereby preventing the stator 4 from turning over or deflecting to facilitate an air gap.

めることにより該枠体に固定されている。1) Prior art In general, the method of fixing the stator of a compressor is as shown in Fig. 1, in which the stator (7) is fitted with bolts (6) inserted through holes (17+) drilled around its periphery. It is fixed to the frame by screwing into a bolt hole (10) drilled in the support leg (4) of (1).

に適宜な表面あらさに管理されるものである。Further, the contact surface (4a) of the support leg (4) is connected to the stator (7).
) The surface roughness is controlled to an appropriate level in order to exert sufficient frictional force to guarantee the tightening strength of the parts.

is provided to improve flatness when the stator is attached to the frame (1), prevent the stator from falling over, warp, etc., and facilitate the creation of an air gap between the stator and the rotor (9). I'm looking forward to it.

動不良等を招くものであった。The frame (1) is actually manufactured in mass production, and it is difficult to uniformly control the surface roughness of the contact surface (4'a), so unevenness in the surface roughness is avoided. In addition, the seat push portion αB provided on a part of the stator (7) is designed to improve the surface roughness of the contact surface (4a) of the support leg (4) in order to strengthen the degree of constriction of the stator core. Even if it is roughened, it is difficult to dig into the seat push part (18), so that sufficient fixing strength of the stator (7) to the frame body (1) cannot be obtained, and due to impact etc. during transportation of the compressor, etc. The stator (7) caused a horizontal air gap failure, a compressor startup failure, etc.
